HOW TO REPAiR CORRUPT/BROKEN PHOTOS AND iMAGE FiLES
HTML-код
- Опубликовано: 5 мар 2018
- Follow this guide to repair your broken image files by swapping out their corrupt headers with working ones in a HEX editor! This method has been tested by me, and I can confirm that it works with Canon, Nikon and Olympus RAW image formats. Other formats like Sony and etc. should work as well.

Some of you have requested a written guide, so here it is: pastebin.com/Hx5KRKRF
I'll make a part 2 ASAP. Stay tuned!
After I did all the instructions. the image turns into black? what should I do? or did i do something wrong? pls help
@@bossbraiofficial Either image data itself is corrupted or you managed to somehow glue header for thumbnail to main image data.
FILE down please reupp!! thhx

please help me, win10 got corrupt after an update and had to reinstall. pressed the wrong option upon reinstallation which wiped out all my data. most of it i backedup on cloud storage but i have about 6 photo albums that i need to be repaired. the recovery tool EaseUS recovered the files however it's corrupt. i checked in Hex editor and it's all showing 0s in the string. please help me i'm desperate. 12years of memories in those albums :(
hit like if you didn't understand anything
hahaha
Clean the wax outta your ears.
LOL I thought it was me at first. But f me... Didn't understand a word
Piece of cake. Imagine having only 200 images to repair
LOL
Same here brother
i have about 1000 images to recover 🤦
hey dude...big thanks for jpg repair walkthrough...for me it works for some but not others. but the most important thing is you have shown that you can do these things yourself rather than than paying money for crappy software. massive respect to you.
Thanks for seeing what I'm trying to do here.
@@Pluss1 Thanks for your reply....having had time to play around with stuff..two things stick out...the orientaion of the source camera...which means finding the right header...you might have to try a few before you get it correct. I am sure you prob said all this but thought i would pass that on....Peace.
Thank you. It Really Works! In my case, I Already Find the "FF DA" with a first try so I don't search for other "FF DA". The result = failed. But at second try, I try to search another "FF DA" and I can find it below the first one. Then I replace it from that position and it works. Thanks again, I'm bit frustrated because I think I'd lost my photo but you saved me!
Thanks so much for taking the time to explain the procedure. I'm a dunce when it comes to the code that runs our PCs, but I'd wondered if it was just a few bits corrupted that killed the whole image.
Yes. In fact, just one byte out of place or missing can cause entire image corruption. Usually this would be a MSB (most significant byte).
Some formats are more sensitive to byte order manipulation like PNG, Gif and Avif, but JPG is a little more forgiving.
Open a unimportant jpg image in Notepad++ and look at all that code!
Mess around by moving or changing any character you wish and resave the file.
Keep the image open in a browser window on the left, while you work with Notepad++ on the right.
Your image viewer will quickly tell you when it cannot render the file anymore.
Have fun.
I tried exactly the same process as guided in the video but in the end shows up the same corrupt image anyways that was fun
Are you sure it works?. Can I send you some of my corrupted image please please please respond
Precise and generous. My corrupted files were beyond this recovery and the image header was not available. In Hex editor, all it shown as FF.
Okay. Your vid actually inspired me to write a utility that sticks a JPEG header from an intact reference file to a corrupt JPEG.
Nice! That's why I made the video and posted it in the first place. It would be so great having a working app that could identify raw and compressed image headers on both working and broken files and have it batch copy the working one over the bad ones. I can just imagine how useful it would be for professional photographers and hobbyists.
Only for JPEG right now. I guess I could do similar for popular RAW formats. it's here:
www.disktuna.com/jpgrepair-fix-and-repair-corrupt-jpeg-headers-and-invalid-markers/
Of course I can only test against my library of corrupt JPEGs but it shows this method is much more effective than methods used by tools like Stellar JPEG repair. Drawback is that you need a sample file preferably shot with same camera and settings.
Awesome! I'll give it a try and include it in my next video. There are some things I want to add and explain better than I did here. Yeah, tried the full version of Stellar JPEG Repair, Picture Doctor 2 and JPEG Recovery Professional. Basically just a waste of money, didn't work at all. I'll warn people of buying them and refer them to you.
Great, thanks man!! Free version works, only batch mode disabled. But people can really use it. If you sent me an email (joep@disktuna.com) I can sent you the 'full' version.
That all being said ... I think way over 50% percent of JPEGs people sent me can not be repaired. So no tool or service can, simply because there's no image data in the file. But, for a very large number of corrupt JPEGs that can be fixed, the slap a header on the image data method works better than all those tools you mention.
Hey Neuro,
The majority of the corrupt JPEGs people sent me can not be repaired. Simply because in like your case there's some random non-JPEG data in them, or they're filled with zeros or some byte pattern (FF FF FF FF etc.).
So those can not be fixed because they're impossible to fix not because the utility sucks.
That being said, if you have a file that can not be repaired using the utility, you're more than welcome to send me the file so I can check if it can be repaired and if I need to so modify the utility.
Hi
If I understood well, if I don't find "FF DA" only twice, restore is impossible ? 1st try it worked but after with another images I didn't find "FF DA" but "9F DA" and the repair didn't work. Another time I found "FF DA" one time and after I had the same image.
When I try to search for "FF DA" I get "string not found". Any ideas?
FF DA is the SOS marker. It can mean the data you're looking at simply isn't JPEG data, it can however also mean the damage is not limited to header but also actual image data is affected. Some times you can still fix this but it requires more effort: ruclips.net/video/9XwhGObWCtY/видео.html
this doesn't work in my case since most if not all values in my bad image is 0 ..... (*FF DA value is missing)
I don't want to hack nasa.......i just want to view my photo......
Don't we all? LOL
Got there in the end, though my issues were more technical due to the large video file I was working with. Successfully resolved a corrupted Blue Iris file .bvr video file.
Does not seem to work for me. After replacing some headers some files don't even an .jpg extension, and the ones that do still don't open. In Jpg repair all the images' entrophy is 7.98 - 8.00, which according to the site means they might be encrypted? My brother mentioned something about encryption too. Disk Drill is capable of recovering some of those files, but other than that no other software even allowed me to even see previews. So what is the issue here? Corruption or encryption?
Usually with encryption, identifiable strings of printable characters will appear in sequence amongst the non-printable characters which represent the color-code blocks.
Example:
Color code binary:
SYN. FF. ¢. ¶. Â. NAK. BS. Þ. 9.x.²
Encryption strings:
[bM1%r~śPxȳ#gl+U
Encoded Strings:

Kudos from the guy in the Netherlands you mentioned in the video!
Great video! I started like you, couldn't accept no for an answer.
Thanks! I would not have figured this out, and this video would not have existed if I didn't find and read through your website in the first place. Keep up the great work!
BTW. It appears as if in your example are actually extracting JPEGs from CR2 files. I made a free tool that can do this automatically: www.disktuna.com/jpegdigger-extract-jpeg-from-corrupt-raw-files-nef-cr2-etc/
BTW I now link to your vid from that same page if you're okay with that.
No worries! Yes, it wasn't intentional. I screwed up and forgot I was repairing a CR2 file while making the video, so I added a note @ 04:24, because I couldn't bother recording it over again. Nice software though. I'll have to try it out!
how do i contact the guy from netherlands?
www.disktuna.com, my email is joep@disktuna.com
I know this sounds weird, but I need to way to turn a working image, to a broken one, essentially corrupting it
Here's an idea, put it into a removable drive, delete it, paste more files into the drive, use Recuva (or some other un-deleter program) to search the drive, then if the preview loads, paste more files into the drive until the preview does not show the file.
I followed all the steps and while the preview image looks fine when I open the image it's all gray, you got a solution to this?
For some reason when i press f3 my brightness decreases in that case what do i press?
Fn + F3
Hello i do the same steps but but after clicking on search then find and unchecking case sensitive point and okay
String not found dialogue box appear what i do waiting for urs reply
Hello, I tried doing this to a corrupted image but when I search for FFDA I get an error that there is no such value. When I open the picture with the application, the only value I see is FF
i have the same problem, did you solved it?
I'm sorry, but if all you see everywhere in the file is "FF", then you actually are out of luck using this method. Try data recovery service or software.
@@Pluss1 heloo how about all of them are "00"?
So here’s a question for you.
What if the issue is that you have a corrupt photo but you can’t find which specific photo it is (like when transferring photos from iPhone to laptop)? I found on method of doing so, but it only really works well if you have a small number of files. But I have like 4000 or somewhere around there...do I have no choice but to go through them manually one by one or in small chunks? Or is there some faster way out there that I have yet to find?
Please if anyone knows any shortcuts to speed up this process, let me know! Thanks!!
Well, that question is rather philosophical. You might have Schrödinger's corrupt photo, but you won't know for sure if you don't accidentally stumble upon one. You hard drive might start getting corrupt sectors without you knowing. The best thing you can do AFAIK is to have a regular backup schedule and use a software to only copy new files/the differences between source and backup destination. Even then, you can't be sure if what you backed up was corrupt in the first place. There might be software out there that checks integrity of every single file on your computer, but I haven't done any research or taken any measures to prevent it personally. If you are certain that all of the files on your hard drive are healthy, and you do a full backup using your own Unraid server, you can set up that server to do weekly file integrity checks, in case one of your two Unraid HDDs are getting corrupt sectors, and Unraid will notify you. Which method do you use anyway? I haven't really thought of doing this before.
Please help... Once I type in the FF DA in the text string and remove case sensitive, XVI32 says 'String not found' and the string is all zeros. Is there a way to manually enter data or are the files completely at a loss for recovery or conversion? I have over 500 prom photos that are apparently corrupted. :( Your instructions are awesome and I have watched your tutorial many times. I just have nothing to remove or replace the header.
was there ever a reply to this, I have the same issue with wedding photos
If you know the dimensions that most of your wedding photos were shot at e. g 1024x1024px then that can help. Often the dimension data can get lost during corruption.
1.Drop a working image into Notepad++
2. Inspect within Lines 1 to 7.
3. Move along slowly until you can identify the following bytes:
xFF xC2 NUL DC1 BS
The next 4 bytes that COME directly after that will be your dimensions.
The dimensions share 2bytes each, for width and height.
For example, if you dropped in a jpg image with a width of 1024px and a height of 768px
You would see the following byte representation :
ETX NUL EOT NUL
These 4 bytes will be read by jpg image viewers as 1024 pixels by 768 pixels.
So the complete portion of the line will look like:
xFF xC2 NUL DC1 BS ETX NUL EOT NUL BS ETX SOH
Changing either of dimension values in a text editor like Notepad++ will generally not prevent the jpg from opening. But it will be distorted.
This is is because the original total layout of every pixel was saved to the canvas for the correct proportionate display, when the image was taken, or by a software image editor when the file was saved to jpg format.
It is difficult to reproduce the jpg corruption you are experiencing without the actual file, but keep researching and trying the methods mentioned here in the video., and email the tuna guy😁
I wish you all the best 👌
You just opened the same picture - Can you remake with different photos so show it works?
I didn't. Those are two separate pictures taken right after each other. You can see that one of them has a slightly longer shutter speed and is more tilted than the other.
I have deleted the partition ....now I have recovered the images and videos from the data recovery software but 90% of my images and videos are not able to open...showing that it may be corrupt or broken....can you fix these photos and videos for me
Did u solve it?
if all you did was delete a partition (not recreate it), 100% recovery is possible with the right tools.
Same problem

FF DA string not found on corrupted data but it has on good data PLEASE HELP!!
String not found???
If "FF DA" does not exist, the image is most probably damaged beyond repair.
what a sad. in my photos also say string not found.
It really depends on IF there is actually JPEG data in the file. IF it is then there theoretically is a chance part of image can be restored. FF DA is the SOS marker (start of scan). If entropy for the file is good then it may be JPEG data. IF you have a good header (from same camera) then can some times be fixed. See: ruclips.net/video/0Fyp_YzirNI/видео.html
Some of my most important photos were on PenDrive. Since the pen drive is not open, I recover with recovery software. But the pictures that come in have been lost - clicking on Advanced Repair will require a sample image taken on the same device. But I don't have any samples for that device. What should I do now?
Do not do anything with the pen drive you had your photos on! I will cover how to recover files from flash drives and hard drives in my next video. If you don't have time to wait, I recommend that you read about and test the recovery software on www.disktuna.com/.

Sounds like your files are too damaged to repair. If you want to give it another try, you could contact DiskTuna to have them checked for you.
I tried this all I get are 00 maybe its not read the file right since the file does take up space I tried others still nothing :'(
If your file is all 00's, there is no way to fix them. You need to try data recovery software.

@@DiskTuna WAT METHOD?, I FOLLOW THE STEPS BUT I WRITE THE FF AND DONT WORK.
@@julianmoreno672 He's describing a method to 'transplant' a header from a healthy file to a damaged file. The method working or not has little to do with the software (a hex editor) he is using.

Hi there..i got my pictures in a USB from a photographer.. half of them are corrupted..almost 4gb data.. plz tell can i recover them?
The fastest way to get them back would be to ask the photographer. If that isn't possible, I would follow the guide I've put up here.
OK so I was using FF D8 and leaving the second FF D8 so Block select the Block before the second FF D8. Delete etc and save and i get a half image.
This was from a 256gb micro sd card on a samsung s3 photos direct to sd. lot of corrupted imagees. maybe should report to samsung? Maybe the data is being saved .
There also seems to be a large string of ff ff ff ff ff..... I used the replace function to delete them. searching for 4 lots of ff ff ff ff this had no effect to the partially restored image but reduced the hex string. removing 3 lots ff ff ff same i think replacing 2x ff ff then corrupted the image again. backup and try yourself.
only half an image recovered though. 2 seperate attempts 2 different files.
try recovering a photo without replacing the header, beacause it's obvious in your video that you don't need the corrupt file cause you have the unbroken file
any unbroken file from same camera and setting will do. you don't need the exact same unbroken file of course.
Hi, I tried this on CR2 files. Results = thumbnail of non-corrupt file shows up in the AAA.JPG, but when you click to open AAA.JPG, I only have a totally black image. What am I doing wrong? Your comments/help will be appreciated. Thank you.
same here , did u find a solution ?

cant see in the image, first block is FF and second block is? "TA","DA","D8", other?
It's "DA"
@@Pluss1 bro, and if it's not the header of the image? In my case it's the footer, all the time... What will be the difference in the process? Thanks!
Hi, I followed everything you said step by step, but when I clicked on the resulting image it said We can't open this file....I need serious help
what do i do if it sais string not found?
if FF DA isn't found in damaged file then it may not be JPEG at all OR damage extends beyond header (so FF DA was overwritten). It's similar to this: ruclips.net/video/9XwhGObWCtY/видео.html
Thank you so much, in the meantime I thank you for sharing, registration and deserved likes for your channel, I followed the guide also linked by you, step by step, the only progress that I managed to do is create only the thumbnail preview, but the main remains damaged.
In essence, the damaged photos were recovered from an external memory that has broken, photos taken with a Canon EOS 1200D, among the many halves are intact, while the rest are in light gray, brown, are seen in the middle, but none in black, so I think they are repairable, since with RS repair jpg the only thing I can recreate are the previews, from there I played a bit with the HEX editor, but creating different combinations I can not create a black image or a preview file with the size of the original (the preview is always logically small).
I have no other ideas to recover the blessed photos of my marriage, I've been trying software for months and I think only the hex editor can do the miracle so much hoped for the joy of my wife.
I thank you for everything and God bless you!
P.S: excuse my bad English

I Hope You can Answer and Help Me, THx Buddy....
had the same problem as you
me too had the same problem
If "FF DA" does not exist, the image is most probably damaged beyond repair.
so now what ? where is no other way to fix file ? @@Pluss1
If FF DA isn't there then either it's not JPEG data - or- corruption extends into actual image data. Sometimes with the header from a reference file you can still recover part of the photo. It's basically what I do here:
First 150 KB are overwritten, so entire header + part of image data is gone. In case of video by ransomeware but technique to repair it is generic: ruclips.net/video/k7KB7uUoOrU/видео.html
i also want to fix broken images on various websites while on the wayback machine
Thanks for the video
I get a message 'String not Found'. What am I doing wrong?
Thank you
getting the same prompt as well "string not found"
if string ffda is not found in bad file then damage extends beyond header. it's same as message 'no sos marker found' in jpeg-repair. you can still try to repair, see ruclips.net/video/9XwhGObWCtY/видео.html
nice 600rr my guy. hope youre able to recover ur files.. ride safe
Is there a way to automate the process? Specially if you need to fix thousands of images
Have you found any??
does this app needs internet ?
No hex editor with block mark option for mac? i dont have windows :(
Maybe R-Studio??
I'll look into it and try different ones. I've only tried iHEX, and it didn't work for some reason.
After clicking NO option it shows that "String not Found"!!!
if ffda is not found in bad file then damage extends beyond header. replacing header makes no sense then.
It's the situation where jpeg-repair says 'no sos marker found'. See ruclips.net/video/9XwhGObWCtY/видео.html

Bro actually my pics size its showing 0B and file corrupted how to recover that pics
Try using www.disktuna.com/jpgrepair-fix-and-repair-corrupt-jpeg-headers-and-invalid-markers/.
It isn't working for me. It's actually being saved as the picture I'm taking the header from. Can you tell me if I did something wrong or make any recommendations?
Hi! That should not be possible, because the header is completely separated from the image data. Some times the header can be longer and contain more instances of "FF DA", not two, like I mentioned in the video, and you may have to delete the part from the third or the first instance that appears and up to the top of the HEX code. You should also look for a pattern similar or equal to the one seen after the "DA" block in this video @ 3:24. The pattern I am referring to is "00 0C 03 01 00 02". That's a good sign and you should always delete everything from "FF DA" and up when you see a pattern like that right next to it. I will upload another video mentioning and explaining these exceptions very soon. If the picture you are trying to recover was on a damaged hard drive, it could however become mixed up and show up as a different one. If that's the issue, I would contact a data recovery center.
I stand corrected. It actually happened with one of the photos I just tried to repair. I will upload videos with updates if I manage to come up with a solution to this.
i have thesame problem the corrupted file next to "FF DA" during the first 3 search is not "00 0C 03 01 00 02" but the working picture does have "00 0C 03 01 00 02" after "FF DA".
Try searching more, until you find it. If you cannot find it, try copying and pasting after the first instance of "FF DA", save and check. If it still doesn't work, try after the second, third and forth and so on. If it doesn't work pasting after any of the "FF DA"s, then I don't know. The image could be broken beyond repair.
does this work with raw images ??
