Thank You Gary! While I do know the difference between covering info up and redacting it, I didn’t know Preview could do real redaction! Again, thank you for the education. What would we do without you???
Thanks for the heads up on this great function. Not available on my MacBook Air for some reason. I'm up to date with updates. Not sure why it is not there. I'll investigate.
Yes. ruclips.net/video/_8D0UeiWD84/видео.html But keep in mind that compression only works if there are images in the PDF that are not already well-compressed.
Thanks for this video. I need this feature, and I am glad that it is so conveniently available in preview. However, I will need to find a way to make the redact colour white, without having to draw white box on top all the time. Also, I will need to test this feature on scanned documents, to ensure that pixels are actually being removed, though your test with the image in the file seems to indicate that it will. But just to be sure, I will open the file in Affinity Designer, which is a more extensive PDF editor that allows ungrouping of any layered objects.
Hi. I am having troubles with using Kyocera m2040 printer on mac. It got installed, but sometimes it prints, sometimes doesn’t. It prints pdf but not word files. Again it prints some word files but not pdfs. Sane is the case with Jpeg files. I hope, you help me out. Thanks in advance.
If you place those shapes over text then flatten it … with preview thst would mean “print to pdf” (not save as pdf) then the box layer is now permanent over the text and no other software can remove that shape. I understand flattening a pdf is something most don’t know how to do.
@@macmost I have flattened a pdf with “shapes” over text in preview and opened them on a pc with both acrobat and foxit. You cannot recover the text underneath. Once it’s flattened you cannot “uncover it” in another program. Preview is essentially doing the flattening for you when using the redact tool. It’s a very nice and easy process for the no tech user who would need a few more steps to “print to pdf” and then it asks to overwrite file which many worry about.
@@YouGotPropofol I would not bet on that. A normal user opening it in a normal app may not be able to see under the "shape," but if security is important I wouldn't count on using shapes+flattening to redact.
That's very different, an image file vs a PDF. An image file has pixels that if you "paint" over them, the original pixels are gone. So using an image editor and drawing over pixels with a box or something else erases what was there before. No need to redact.
In some of my PDFs, redacting makes them larger. Much larger. IHNI why. Also happens when I use the Reduce Size in the Quartz Filter. I tried your trick with the ColorSync Utility and that didn't work either.
My guess is that it isn't redacting that is doing it. It is re-saving the file as a new PDF. Your original is probably using some high level of compression for the images. But when you re-save it, a mid-level of compression is being used. So the file gets bigger. That's the same problem you may experience with using "Reduce Size."
@@macmost Interesting. Most, if not all, of them are court documents and I've wondered if that has anything to do with it. Many don't have images, just very long documents. I have plenty of space on my computer, but I like to try your tips and thought I'd ask about it in case someone else is having the same problem. I searched and saw it mentioned here and there without any solution. As always, TY for the great video.
@@IzzyMariel Could be that instead of documents created in a word processor or publishing app, they are simply scanned images of paper. These are then compressed just like photos. If the compression is good to begin with then re-compressing won't improve them and could make the files larger.
Macs just have so much cool functionality right out of the box. Thanks!
Is Gary from America？ I love the voice he speaks and the explanations of his chosen topic. where can l get more Gary? A big fan here🎉🎉😊
@okrtyit8: Yup! he lives in Colorado, never sleeps🤣 or so it seems, has apple juice in his veins and has an encyclopedic memory of all things Apple. 🍎
Thanks Gary, this is very useful. Hope Apple will put in an option to change the redact color.
Sorry I missed your video earlier! Happy Labor Day! Thank you, Gary!👏❤️
Thanks very much, Gary, for this informative video! Very useful tools for redacting in Preview.
Thanks, useful video.
Thanks Gary! This information is totally new for me. I have no words to say for your top notch knowledge. 🌺
I literally need to redact something for the first time today, perfect timing Gary!
Thanks, very useful, I was unaware of this feature!
Very informative thank you
I really enjoy your videos, you explain so well. Thank you for passionate dedication!
I didn't know this! As it happens, I have an immediate need for this tool. Thank you.
this is useful for audit exercise~!
Love you this lecture ❤
Great video. Genius!
Great information
Great info

Gary explains stuff so much more clearly and succinctly than Apple does. 👍😎 Thank you!

Make sure you are working with a PDF document, not some other kind.
I just came across this yesterday, I had always used a box to hide and/or replace something. Is it a new feature?
A few years ago, if I remember right.
Can you find and redact all occurrences of the same word quickly like find & replace ?
No, but see 4:31 for a suggestion.
Is there an option to compress a pdf in iOS or MacOS?
Yes. ruclips.net/video/_8D0UeiWD84/видео.html But keep in mind that compression only works if there are images in the PDF that are not already well-compressed.
Why doesn't Preview have white redaction feature like PDF Expert?

You can't make it white. Drawing a white box on top is your only option. At least in Preview.

I'd contact support for that company.
Pointer control not showing on my iPhone please give me some information about this 😢😖
Pointer control? Not sure what you mean by that.

Not necessarily. You may not be able to get to it in Preview, but the data may still be in the file unless you use the redact tool.

How can you redact something in a photo like a license plate?
That's very different, an image file vs a PDF. An image file has pixels that if you "paint" over them, the original pixels are gone. So using an image editor and drawing over pixels with a box or something else erases what was there before. No need to redact.
My redact tool is greyed out.
Are you working with a PDF, not an image? Is the PDF maybe locked/password protected?

This is going to be superb for evidencing some teaching stuff towards medical qualifications, without actively sharing students personal information.
First viewer. ❤
This is more a hiding of the text, not a redaction.
Did you watch the video? It specifically doesn't hide the text, but redacts. Meaning that the text is removed completely, not just hidden.
