Summary: * *JPEG*: tiny file size, lossy compression. Bad at sharp edges/curves. * *GIF*: lossless compression, animatable. Only 256 colours. * *PNG*: lossless compression, no compression artifacts, transparency. Larger file size. * *TIFF*: supports any colour palette and compression as it's a container format, popular among photographers. Very large file size. * *SVG*: scalable without any quality loss. File size depends on how complex the image is, rather than the amount of pixels. * *RAW*: raw, minimally processed data from camera. * *HEIF*: supports animation and is higher quality than JPEG and GIF. * *BMP*: stores each pixel individually. Supports transparency. Very large file size. Note: file sizes aren't always smaller or larger; some formats are optimised for certain types of images. For example, PNG is smallest if you use few different colours. Edit: updated with information from the replies.
To add, TIFFs are much bigger, SVG size is dependent on complexity of shape rather than amount of "stuff" in the image - i.e. an SVG of a simple rectangle with a simple image gradient works extremely well in an SVG, a photo would be terrible, and RAW files are minimally rather than unprocessed.
Correction: "A RAW file doesn't just contain the information to create a picture, it contains the information needed to create the information needed to create one"
Yep. They're versatile. I first loved them when I was designing a header and realized that I could put my png logo over the background color of the header. Everything that was not the png logo itself was transparent. Blew me away and looked so cool!
IKR, just don't forget to turn on compression. I was using wkhtmltoimage and the damn thing doesn't turn on compression by default, and I didn't notice it until my php script ran out of memory one day.
If I may pop in on this, JPEGs can actually be very high quality (95+%) and even truly Lossless (which many people don't know) - however, the file sizes would then be in the same realm as low-compression PNGs or BMPs. If I may explain further, part of the reason why you are seeing sooo many JPEGs online, is because many companies/servers/etc post-compress submitted images as JPGs to save server space. Sadly though, this results in many nice art/logos/etc appearing online as artifact-full-JPEGs, as you say, 'all over the place'.
If you don't know anything about images, then .png should be your default. You can never go wrong with .png unless you're an expert and know what you need. .jpg is generally the best format for photographs, but you can often save the same photos as .png in only slightly more space and it's technically lossless which .jpg is not. .bmp is a generally awful format to use. The only excusable time to use .bmp is when you're making very tiny images such as icons or oldschool-type graphics, and even then there are alternative image formats such as .ico or .pck.
You don't want to go there son - you don't want to go there. There are still people retarded enough to claim that vinyl or cassettes sound better than CD.
My favorite image format is actually PNG for a few reasons: 1. It supports transparency, and that’s a great feature to have for me especially, since I’m a graphics designer for myself. 2. The quality of images PNG provides are actually very good! Unlike JPEGs which have those “JPEG Artifacts”, as I like to call them, when viewed up close, and it looks absolutely terrible! 3. PNGs don’t take up that much space. I mean, JPEGs do take up a lot less space than PNGs, but mostly due to the JPEG Compression Artifacts, but PNGs still don’t take up that much more space than JPEGs anyways, since you’ll be getting a much better quality image with just a general file size increase. And you’ll probably notice that I compared PNGs to JPEGs, and in case you haven’t figured it out yet, I despise JPEGs for the reasons I stated above. Additionally, I’ll use TIFF images exclusively for Desktop Pictures & Wallpapers.
JPEG artifacts only appear on high compression. I upload all my images (photos taken with my DSLR) to flickr as jpg (highest quality setting). I did a comparison between 16-bit TIFF (no compression at all, 150 MB file size) and a highest-quality jpg (15 MB file size). It's impossible to tell the difference. I really tried, going into 100% view. Looks exactly the same. At a fraction of the size.EDIT: I was wrong. I had another look. If you zoom deep into the pictures, the jpeg that the nikon raw converter exports has some strange "pixel regions" and has less resolution that the tif. However, I highly doubt one zooms into the image like that. The problem with tif is, you cannot upload it to flickr, and that makes sense - one single file is 100 MB...
@@marcozg77 That's because jpeg is designed for pictures. You would not look professional if you tried to use jpegs for graphic design on websites, it looks awful no matter how low the compression is, and also doesn't support transparency. the better format nowadays is webp as it's both as compressable as jpeg (lossy) and as high quality as png (lossless) while also being the same size as a jpeg. You can also have animated pictures in full quality with it, although webm is better for this when it comes to filesize. Only downside at the moment is iOS and safari doesn't support webp, but it will be more common in the future when more applications support it. Once safari and ios browsers support webp we can expect all major companies to adopt it, but for now it's either serving jpeg for safari/ios users and webp for the rest, or just waiting to adopt it until everyone can use webp.
GIF's use indexed colours or palette, meaning a GIF can only have up to 256 colours but you can chose what colours to have in the palette from 24-bit RGB color space. Animated GIF's can have different pallete for each frame. Also GIFs can have one color defined as a transparency. but making it a pixely edged transparency. PNG's can have a fourth layer of color witch is aplha (or RGBA), giving more smoother transparency edges. PNG's can be smaller than JPEG's if the image has lot of same color surfaces. Company logos, witch are in two colors can be much smaller filesize and better in quality when saved in PNG and larger and with artifacts if in JPEG's. Canon new cameras have a RAW format with Double Pixel data (DP) witch gives new option to make small focus adjustments after the photo is taken.
Yeah that sounds right. Since that's cleared up I'll jo to the zoo to look a the jorillas. Then I'll jo walk my jolden retriever to the park and play my juitar.
Video format, codec, container video please! For example, mkv (container) x264 (video codec), h.264 (video format)... and of course the audio and subtitles side
x264 isn't a codec. It's an open source compression library, just like x265. h.264 IS a codec, along with h.265, VC-1, MPEG2, MPEG4, DNxHR, ProRes, etc.
*YES!* More please. Typically it's difficult to find a quick, fun fact YoutTube video which teaches the view of digital file formats and how they came to be -- very odd given that we all use computers and mobile devices to view content on RUclips. There are so many different file types that I think this channel could again -- as has always -- exceeded my expectations. I look forward to more of these types of videos in the future! Thanks.
PNG - Best general purpose format. Lossless compression, so good image quality for photos, text, graphics etc. JPEG - Bullshit. Should only be used when nothing matters. Doesn't work at all for text or graphics due to lossy compression. SVG - Good for graphics. Scaleable, so no limited resolutions. Doesn't work for photos. GIF - Outdated. Completely replaced by PNG. Shouldn't be used anymore due to limited resolution and colors. BMP - Old, but very simple. PNG is superior for general use, but BMP is marvelous for integration into custom programs. TIFF - Can contain lots of different formats. Don't use it unless you know what you are doing. If you do know it is great for keeping image quality, specifically higher than 8bit per color channel (R,G,B). Supports different color spaces, thus very useful for professional printing (CMYK). RAW - Best for editing. Not useful for any other purpose.
Most of my photos are saved in JPEG and so are most photos on the web. They save a lot more space on my hard disk, and I can barely tell the image quality difference from PNG. I use PNG for project files that must retain 100% quality though many saves.
Yes! More videos like this, please. I'm a self-taught/still learning web dev and graphic designer and clear and concise information about all of the things you could cover is really lacking on the internet. It's there, but it's from tons of different sources, often times they're long articles that take while to read, blah blah blah. You should definitely do an audio formats video and probably not even stop there.
@baconmedia93 JPEG photos taken in cameras normally store metadata too, like the location where the photo was taken, the hour and date, the camera used, etc. If someone has a bit of a brain they can know your location by seeing this metadata from a phtoo you send
@alroightmaite No, you didn't understand the joke because it was not funny. Saving your location only adds a few bytes of extra space, virtually nothing.
I want to start this by saying that this is a really good summary of the differences in graphics formats, really well done, Techquickie! Uh..oh.. here it comes.. akshyally... GIF is not limited to 256 colors. In GIF internal terminology a "full image" is called "logical screen" and it consists of number of "images", which each have maximum of 256 colors. One can compose a logical screen from 16x16 pixel images so that any number for available 24 bit RGB888 colors can be used in the final image.. errr.. logical screen.. Most GIF loaders that resolve into 24/32 bit final output are able to read such GIF files. It's just ultra-rare to find such file since most encoders don't really care about creating such files. :) I know, dumb trivia.. please don't flame, I really like this video!
John did a great job in this video, don't get the negative comments about that. On a completely different note, he reminds a lot of Michael Swaim (from After Hours) in this video for some reason - maybe it's the facial hair (not used to seeing him with it).
TIFF isn't necessarily an image format on itself; it's a container format, more meant to be some sort of album or bookcase to store images in. Yes, multiple. TIFF supports multiple images stored in a single file. Each image gets its own little data header that tells the program reading it what image format is used, what size it is and where to find the next header in the file. This also means that for single images TIFF will always be a larger file than its original format, but it offers great flexibility as each image can be in a different format and size.
yeah. I have no idea what 4:2:2 means... and what sRGB is exaclty :( Or... how to set up my computer to work in 10bit with my 10bit TV... is it even possible? (someone said that 10bit cannot even go through on hdmi in some color spaces...)
To display anything in 10bit you HAVE to use profesional graphic cards (such as RadeonPro or Nvidia Quadro) and a monitor that actually can display so many colors + use new version of displayport.
What Im hearing is JPEG for absolute compression, GIF for graphical design. PNG for everything, but higher file sizes than JPEG. TIFF for graphical design in multiple colour spaces. SVG for flexibility in scaling an image - most likely use case being graphical design. Raw for photography where quality and flexibility of editing are most important.
Oh it's there. other people have noticed it as well. very very small. some people suspect the sensor has been damaged from an over exposure at some point. someone said that they have seen that before due to a laser light (but it was a purple dot). who knows. I'm sure LTT is looking into it.
@linus i am sorry to even dream of getting a second or two of your attention... but.. seriously... this was really useful to a lot of people. personally, i knew most of it or at least the bits that i needed/wanted to. but... this, this is useful to a lot of people and will be re-watched once in a while by the same people, that needed info on specific issues. this sort of material can and will be a milk cow, considering the effort put in, beating the ltt main channel. because, this is info people will be coming back to to revise. personally, been fiddling with raw files for years... so this sort of info is not anything new to me and i think i might drop an angle on some statements.. but... without drifting off - this was a GOOD bit. think this through: 4 years, an under 7 minutes video with no hardware involved, except a dude editing it. (yes, editing costs too, but nowhere near to what you spend on bigger vids). SOME of your vids are already used in college/uni education as examples... why not monopolizing it, while at it? simples.. vgahdmidP style videos are useful... but they are scarce and hard to find. make a channel literally meant to explain all the basics. get them console peasants to actually understand, what are they arguing about, the next time they try defending a console. educate the peasants!
Def enjoyed this video and made it much easier to understand. I've always had a fascination towards all file extensions be it very specific ones, branded / company owned ones, and even obsolete ones, An idea?: start a mini series that go over ALL the file extensions that have ever existed in vids with the same style and manner you did here, there pros, cons, how they came about, there demise, room for improvements, and future potential replacers, that would be a really cool lil mini series you guys can start. I think
Finally someone that says "GIF" as it should be said. Even the creator was an idiot about it. Nice video, but you should make a "long story short" section with the most important things at the end.
I think I would disagree that gif is the right choice for online graphics and logos. I’ll always go with a PNG. Gifs DO support transparency, but not partial transparency (meaning if you need your image to go over a dynamic or gradient background, the edges may look to abrupt with a gif). A good rule of thumb: - JPEG for photos - PNG for graphics - GIF for light animations - SVG for scalable graphics (although some browsers and software do no support SVG) - BMP is dead
I know LTT is in Canada but what is this guy's accent? It sounds kind of Mid-Atlantic, like he's from Baltimore, Philly or D.C. Is he one of a 'fellow American' that successfully emigrated north?
RainbowLox I'm not aware. But there are two other formats that have animation capabilities from the png company, so... But still weren't important enough to mentioned. Because they couldn't took over gif.
It pisses me off they didn't mention PNGs are animatable just like GIFs, at lower file sizes for the same quality, making GIF completely useless. It is only used because of popularity.
Tell me if I got this wrong: .BMP - decent quality, huge file size .JPEG - loss compression, smaller file size, bad for sharp colored images, great for photography & favored by most clients .GIF - Animated images, smaller color scale, sharper edges for pics with high color difference .PNG - Transparency support, lossless compression, bigger file size, good quality .TIFF - Favored by photographers, has wider color scale .SVG - Resizing image maintains its quality for some odd reason .RAW - Has bare information to create image. When encoding it, you have many more configurations than usual and is also favored by photographers.
One thing that should be noted - BMP or PPM are not a format, they are basically uncompressed image data, or raw data, saved as is. What makes it a format is actually header that defines how big the image is (the dimensions), and also defines color space format alongside with bit depth. BMP is a full binary format that has header defined by a specific memory structure and it is also widely supported by various image processing apps (viewers, editors, etc.), while PPM is also a binary format, but it's soft binary, it can also be represented by textual data. The header is in plain text format (ASCII), and based on the informations in the header, the file could be binary or plain text. Like BMP, it includes bit depth, color space, and also image dimensions. It's by far most interesting raw data image format, because it gives an option to literally write an entire image in plain text, and still work. It even supports comments inside the image and it more or less represents a source code file instead which is then translated by a processor into binary image data in memory.
@Tournel Henry You can always download a camera app (I recommend Open Camera) that will let you choose a different save format (unless your phone manufacturer locks their phone down). The JPG saving is not determined by hardware but by software.
@Tournel Henry maybe your specs were too low (like not enough RAM to load the whole image at once or too slow memory to save it) as for png not being geotagged, some apps can even save it to a second file (like xml)
i came here expecting to see 3 different people with same clothes that look like linus when they did comparisions to JPEG , GIF ,PNG . sadly i was dissapointed
Generalize that as "source format > PNG > All". Even then I would say (for still imageS) source format > FLIF > A: PNG or B: JPG depending on content. Hopefully in the future FLIF will find greater adoption.
This video came up in my recommended videos (even though I've already seen it), and I clicked on it purely because I was wondering what happened to him.
PNG is an image file container format that also has some newer (than the first giff and jpg standards) compression algorithms as part of the standard. There is nothing stopping you from using JPG etc compression inside the container. It was built to allow easy interchange and more modern features than JPG and GIF. Saying that "PNG is larger than JPG" is a bit of a misnomer. Some one should go and read the PNG standard which explains all of this stuff.

So which one is good??
png for sure
png compression is lossless or lossy. depends on settings you choose. most png files are encoded in lossy format
"A RAW files isn't an actual picture, but it just contains the information to create one."
I'm pretty sure that's true of all digital image formats.
So you too did watch the squish the cat over the shoulder video. HAHA
@Li Feng Yes. The difference is they store all the information, whereas lossy formats only store a percentage of the information.
You are all JPEG images

John did a great job in this video, don't get the negative comments about that. On a completely different note, he reminds a lot of Michael Swaim (from After Hours) in this video for some reason - maybe it's the facial hair (not used to seeing him with it).
PNG Masterace !!!
Yeah! JPEG peasants
You plebs, I only look at raw images.
Adam FromFin I don't think you understood what raw image is
Kaustubh Chaudhary
Yeah boi!
PNG all the way!
PNG sucks because it doesn't support CMYK colors, JPG let's you print in CMYK.

WTF!!! I searched the whole comments section!! No one noticed Linus's face there?! He looks better this way tho.
Nice
First comment talks about Linus
Great Video. Can you guys do "Audio Formats" next? Thank you!
1:15 when the bass drops
I was hoping someone else noticed that!
?рорггг
Woah that's d e e p. I mean smooth lol
TIFF isn't necessarily an image format on itself; it's a container format, more meant to be some sort of album or bookcase to store images in. Yes, multiple. TIFF supports multiple images stored in a single file. Each image gets its own little data header that tells the program reading it what image format is used, what size it is and where to find the next header in the file. This also means that for single images TIFF will always be a larger file than its original format, but it offers great flexibility as each image can be in a different format and size.
Colour spaces explained!!
yeah.
I have no idea what 4:2:2 means... and what sRGB is exaclty :(
Or... how to set up my computer to work in 10bit with my 10bit TV... is it even possible?
(someone said that 10bit cannot even go through on hdmi in some color spaces...)
To display anything in 10bit you HAVE to use profesional graphic cards (such as RadeonPro or Nvidia Quadro) and a monitor that actually can display so many colors + use new version of displayport.
Yeah!
4:2:2? Search Wikipedia for "chroma subsampling" and you're done. Vast majority of what consumers get is 4:2:0 and is, when done properly, quite good.
This was soooooo understandable.
What Im hearing is JPEG for absolute compression,
GIF for graphical design.
PNG for everything, but higher file sizes than JPEG.
TIFF for graphical design in multiple colour spaces.
SVG for flexibility in scaling an image - most likely use case being graphical design.
Raw for photography where quality and flexibility of editing are most important.
BLUE DOT!!!! what is it? Is it on purpose or an issue with the RED cameras?
Ryan Mercier I don't see a blue dot
Oh it's there. other people have noticed it as well. very very small. some people suspect the sensor has been damaged from an over exposure at some point. someone said that they have seen that before due to a laser light (but it was a purple dot). who knows. I'm sure LTT is looking into it.
wouldn't call it small it's huge...
I shouldn't have looked. Now all I see is the blue dot!!!
where is it? i dont see any blue dots --"
watching from 5" phone
That dead blue pixel on his jacket is beginning to bother me...
Now that you mentioned it, me too. ':D
Watch bait? xD
Yup :P
Jack Le Is it visible at 480p? It's as high I can watch with on my mobile.
Lexyvil yeah but you have to squint your eyes really hard -.-
@linus i am sorry to even dream of getting a second or two of your attention... but.. seriously... this was really useful to a lot of people. personally, i knew most of it or at least the bits that i needed/wanted to. but... this, this is useful to a lot of people and will be re-watched once in a while by the same people, that needed info on specific issues. this sort of material can and will be a milk cow, considering the effort put in, beating the ltt main channel. because, this is info people will be coming back to to revise.
personally, been fiddling with raw files for years... so this sort of info is not anything new to me and i think i might drop an angle on some statements.. but... without drifting off - this was a GOOD bit. think this through: 4 years, an under 7 minutes video with no hardware involved, except a dude editing it. (yes, editing costs too, but nowhere near to what you spend on bigger vids).
SOME of your vids are already used in college/uni education as examples... why not monopolizing it, while at it?
simples.. vgahdmidP style videos are useful... but they are scarce and hard to find. make a channel literally meant to explain all the basics. get them console peasants to actually understand, what are they arguing about, the next time they try defending a console. educate the peasants!
Was this the guy that got fired?
according to linked in he still works there
Seen this video pop up but haven't seen him in any other recent videos and thought the same.
0:08 is actually a pretty touching story.
Ye
Def enjoyed this video and made it much easier to understand. I've always had a fascination towards all file extensions be it very specific ones, branded / company owned ones, and even obsolete ones,
An idea?: start a mini series that go over ALL the file extensions that have ever existed in vids with the same style and manner you did here, there pros, cons, how they came about, there demise, room for improvements, and future potential replacers, that would be a really cool lil mini series you guys can start. I think
WHAT DID YOU DO TO TO LUKE?!
I thought for a second they hired someone new.
It's the ginger beard :)
But nope its just Asian luke
One of the best informational videos out there on this topic.
This just popped up in my recommendations. Where is this guy? lol haven't seen him in a while.
YEAH!! Does he still work for Linus? Inquiring minds need to know!
linus with make-up what a change. 1st?
I still use BMP for certain kinds of editing like making glitch art, as it allows pretty awesome techniques you can't use in compressed formats.
It's GIF, not GIF.
boi
🎁 jift
agreed
I always thought it was GIF
It's Gif, with a silent G.
Linus got tanned? I almost didn't recognize him
Finally someone that says "GIF" as it should be said. Even the creator was an idiot about it. Nice video, but you should make a "long story short" section with the most important things at the end.
I usually save my photos as TIFFs so I can re-edit the photo without saving it as PSD.
Lossy compression is for plebs, png master race
Jabberwockxeno .DDS anyday because dxt compression masterrace....
Roman society reference
BPG is already dead because of high encoding time. FLIF is the best solution coming up. It throws WebP under the bus as well.
PNG is only 8-bit, though. DNG ftw!
Tiff MASTER RACE!
I think I would disagree that gif is the right choice for online graphics and logos. I’ll always go with a PNG.
Gifs DO support transparency, but not partial transparency (meaning if you need your image to go over a dynamic or gradient background, the edges may look to abrupt with a gif).
A good rule of thumb:
- JPEG for photos
- PNG for graphics
- GIF for light animations
- SVG for scalable graphics (although some browsers and software do no support SVG)
- BMP is dead
It's not that I dislike Linus or Luke, I really don't. I just really like John!
Keep it up John.
4moreYears!
aka American Linus
I know LTT is in Canada but what is this guy's accent? It sounds kind of Mid-Atlantic, like he's from Baltimore, Philly or D.C. Is he one of a 'fellow American' that successfully emigrated north?
Gifs also supports transparency as far as I’m aware.
RainbowLox I'm not aware. But there are two other formats that have animation capabilities from the png company, so... But still weren't important enough to mentioned. Because they couldn't took over gif.
Yes they do
RainbowLox yeah but you gotta sacrifice 1 of 256 colors
Transparency yes, partial transparency (alpha channel) no. It’s awful.
The way you explain makes it seem so easy! It really helped me! Thank you!
It pisses me off they didn't mention PNGs are animatable just like GIFs, at lower file sizes for the same quality, making GIF completely useless. It is only used because of popularity.
Mpeg , MP4 , AVI , WAV ,MP3 , MIDI and many others files here we come.....
Midi isn't audio ;-)
Mpeg, mp4 and avi arent audio files either? Op didnt even say they are :D
never said it is . shot in the foot troll?
ys. I would like more episodes. I always wonderd which format is better and this video solved it. thanks
More file formats!!!
Now i know, this is where I always struggle is, when saving a photo
Tell me if I got this wrong:
.BMP - decent quality, huge file size
.JPEG - loss compression, smaller file size, bad for sharp colored images, great for photography & favored by most clients
.GIF - Animated images, smaller color scale, sharper edges for pics with high color difference
.PNG - Transparency support, lossless compression, bigger file size, good quality
.TIFF - Favored by photographers, has wider color scale
.SVG - Resizing image maintains its quality for some odd reason
.RAW - Has bare information to create image. When encoding it, you have many more configurations than usual and is also favored by photographers.
" *T U N N E L B E A R V P N !* "
😂😂😂
Audio please, like if you want it too
Easy, there's MP3, FLAC, and WRONG
MP3 is a thing of the past. We AAC now.
WAV IS BETTER THAN FLAC
Flac Or Gtfo. Flac uses checksums.
I heard him fine ;)
This was crazy helpful. I'll be looking for the audio and video versions next
Linus looks weird today
That is because it is not Linus talking in this Video
Wait really?@@stephensnell5707
5:19, i would like to know more about file types.
One thing that should be noted - BMP or PPM are not a format, they are basically uncompressed image data, or raw data, saved as is. What makes it a format is actually header that defines how big the image is (the dimensions), and also defines color space format alongside with bit depth. BMP is a full binary format that has header defined by a specific memory structure and it is also widely supported by various image processing apps (viewers, editors, etc.), while PPM is also a binary format, but it's soft binary, it can also be represented by textual data. The header is in plain text format (ASCII), and based on the informations in the header, the file could be binary or plain text. Like BMP, it includes bit depth, color space, and also image dimensions. It's by far most interesting raw data image format, because it gives an option to literally write an entire image in plain text, and still work. It even supports comments inside the image and it more or less represents a source code file instead which is then translated by a processor into binary image data in memory.
1:13 that bass drop, dang. 🤣
I was taught that PNG stood for "PNG's Not Gif", similar to GNU.
Yes, we want more videos like this !!!
Keep up the good work guys !!
Very helpful. 8.5/10
"Hawtdawg!"
SOMEBODY GIVE THIS MAN A RAISE! Wonderful explanation!!!
why my smartphone camera don't allow another format than JPG??? And why is JPG and not JPEG?? I'm confused
jpg is the prefix of jpeg and you phone software has a problem if it doesn't accept other formats.
you can download a different camera app
Its the same so chillllll.
@Tournel Henry You can always download a camera app (I recommend Open Camera) that will let you choose a different save format (unless your phone manufacturer locks their phone down). The JPG saving is not determined by hardware but by software.
@Tournel Henry maybe your specs were too low (like not enough RAM to load the whole image at once or too slow memory to save it)
as for png not being geotagged, some apps can even save it to a second file (like xml)
needs more JPEG
an Intel Core i7 Quad-core Processor , i need you
an Intel Core i7 Quad-core Processor I have you
I hear Ryzen's been kicking your ass. Quad-core's just don't have the muscle to fight back
Made it clearer for me I until now after watching this video I was unsure about the different file formats and what they had in common
i came here expecting to see 3 different people with same clothes that look like linus when they did comparisions to JPEG , GIF ,PNG . sadly i was dissapointed
4:02 anyone else sees the blue dot on the left of his chest?
I searched this comment for hours. I thought my monitor was broken xD
i love these tech videos
You forgot ICO files
tga etc
ico files are useless outside icons, they can be "hinted" but not really practical in other cases
hashtag bluedot
Where is this bluedot I have heard of? Can't see it in any of the videos.
I thought you were talking about the festival
Definitely do more videos like this, this is crazy helpful.
PNG > All.
PSD > PNG > All else. Wouldn't like to lose my layers, masks and non-RGBA channels every time I save an image.
i-R7 Rock jpeg > all
depends what you're doing... as explained in the video, did you watch it?
Generalize that as "source format > PNG > All". Even then I would say (for still imageS) source format > FLIF > A: PNG or B: JPG depending on content. Hopefully in the future FLIF will find greater adoption.
PNG is great when it's not printed
Tiff has more advantages, but less compatibility when it comes to Web
only me notecind that dead ass pixel just a bid under the middel???
RIP jpeg 2000, could have been good. Great video btw
LOL no word about BMP XDD
That doesn't exist
@@froggyfan one advantage of BMP is its very simple, thus can be used as a stub format for something makes developers life easier
@WalkinOSF ok
LoL yeah BMP deserved a mention.
Video file formats plz.
Clear, precise and straight to the point. I love it!
I know there's nothing he can do about it, but his voice drives me insane.
blue dot on your shirt bruh...
RAW images are amazing, editing them is so much helpful, then converting them to PNG or JPEG help.
Fun fact : This guy got fired
He got fired?!
This video came up in my recommended videos (even though I've already seen it), and I clicked on it purely because I was wondering what happened to him.
seems about as complex as English
(there's theirs) (to too two) (many mini) differences.
there they're their
compress compress
Looking forward to hear about those audio formats!
They say the king of Spain had a lisp...
Hat dawg
PNG is an image file container format that also has some newer (than the first giff and jpg standards) compression algorithms as part of the standard. There is nothing stopping you from using JPG etc compression inside the container. It was built to allow easy interchange and more modern features than JPG and GIF.
Saying that "PNG is larger than JPG" is a bit of a misnomer. Some one should go and read the PNG standard which explains all of this stuff.
He looks so upset all the time
What about MPEG???
TOXIC VOID What about Pepe?
That's a video format silly
Great video with best explanations I have seen in a very concise timeframe. Well done!
GO DUKE!!! Great video.
