Cannot highlight text in a PDF.

[willm26591030]

Too hard??  I have been using Adobe products for 20 years and never had a single problem highlighting a pdf.  Today I find I can't highlight a PDF and I really need to.  I have spent the entire day, its now 3:30pm, trolling the internet trying to find out how to highlight and Adobe PDF document.  Epic fail Adobe.

Hi willm26591030,

Are you using the desktop app on a Windows/Mac computer or the mobile app on an iPad/iPhone or Android tablet/phone?  (Your forum post appeared in the mobile forum.  But it is not clear which app you actually use.)

It sounds like you have a different problem.  The other users in this forum thread had questions about how to find the commenting tools in the new mobile Reader app - Adobe Acrobat Reader for iOS or Android.

Your problem may be caused by the type of your PDF document.

Here are the most common cases.

(a) Scanned PDF document containing no real text

Try selecting text instead of highlighting text.  If you cannot select text at all (no matter how hard you try), your PDF document is likely a scanned PDF.  You can only add Text Markup annotations (Highlight, Underline, Strikeout) to real text, not to image of text.  You need to run OCR (Optical Character Recognition) software to turn images of text into real text.

(b) Secured/protected PDF document

The security settings or restrictions of the PDF document explicitly disallow commenting.  The author/distributor of the PDF document does not want you to add comments to it.  All of the commenting tools will be disabled in this case.

(c) Encrypted PDF document

When security settings (e.g. password, certificate) or restrictions are added to a PDF document, the document becomes encrypted.  Unlike the desktop version of Adobe Reader, the mobile Adobe Acrobat Reader apps (for iOS, Android, Windows Phone) have the known limitation where changes cannot be saved to encrypted PDF documents.  Therefore, users are not able to make any changes to encrypted PDF documents.  The easiest way to work around the problem is to use the desktop version of Adobe Reader.

Pleas let us know if you would like us to examine your PDF document to identify the particular reason why you cannot highlight text.

I had the issue of not being able to hightlight when I did saved my document as "print to pdf". this is what I did:

• Open the "Start" menu and in the search tab and type: Turn Windows features on or off.
•  uncheck the feature of "Microsoft Print to PDF".
• check the feature of "Microsoft Print to PDF" back on

and that worked for me and I can do highlight now.

good luck.

Thanks James, in my version (Acrobat Pro DC) that option needed to be activated, as well. Must have been the almighty hand of Adobe to make such a change secretly. I'd wish they strated to talk to their users before that decide on USr Interface matters. I've added your method to my Acrobat Cheat Sheet (over a page long now).

Thabks again

Here's my solution: open PDFs in Microsoft Word - a program where highlighting is simple, and works the way it's supposed to. I tried for an hour to make it work in Acrobat, and couldn't get it to. Adobe, Acrobat is janky and the tool process is opaque and near unusable. Look at Word, learn, and fix.

Hi @Paul Vinger, Voice Actor,

Sorry for the experience. 

Anything specific that you would like to share with us to investigate? Like, is the issue related to a speicifc file, do you see any error messages, or a screen recording of the entire event happening for better understanding.

Look forward to hearing from you.

The solution is to print to pdf from the document you are trying to highlight.  The 'print' action changes the format to recognizable text!  Now you can highlight!

In my case, I had to chance the opacity of the highlight, which was set to 0%.

It's just unclear to me why we now have to use a workaround for something that we've been doing for years. When I'm balancing my checkbook, I highlight each item on the statement as I match it to my checkbook. In the past, I've always been able to just select the amount and highlight it. NOW, it takes more steps plus it will only allow me to do it on the first page of the document. It doesn't make sense to update software and actually add more clicks limit what the user can do. Pretty much the opposite of good UX.

Hi @Kathy3870966209ph,

Hope you are doing well. Sorry for the trouble.

What you mention, shouldn't be happening. When you long press to select a text, you should get a dropdown (Android) or side-menubar (iOS) which has the option to highlight, underline or comment. 

Is this not something you see when you try to? Would you mind giving this a try and letting us know if that works?

If it doesn't, please feel free to share a screen recording video of the incident and we can get it checked.

Using a PC, not a phone.

Tested previously saved documents and it worked fine, so I deleted the
document and re-downloaded it. That seemed to solve the problem.

@Kathy3870966209ph That's good news then.

Thanks for keeping me informed.
