Acrobat and Signatures: "This image file is corrupt"

[alistairg39330077]

Hi all. I'm trying to sign a document on behalf of a colleague. When I upload their signature via "FILL AND SIGN YOURSELF" as a .jpg or .png I get "This image file is corrupt" in a red box. In attempting to do this I've now removed my own signature, and when I re-up that file, I get the same message. So it is clearly not the image files. Tried rebooting the computer (MacBook Pro) and I have also tried moving the files to my desktop... no dice. What is going on here please?!

Same issue here! Running macOS Tahoe 26.0.1.

Where you at, Adobe Support?

Same issue. the solution is uninstall and reinstall adobe acrobat but this it is just temp solution, you will get back same error.

Did that. Same problem. Adobe sucks and their "support" team is too lame to respond.

[german_6217]

are you planning to resolve that issue, Adobe?

Have just hit the same issue. Have updated to macOS 15.7.2 - have uninstalled and reinstalled Adobe. Nothing is working. I need this feature multiple times a day, Adobe Support - where is the fix?

Same issue for me and I am a frequent user of this feature. Tried uploading multiple image types to no avail keeps on flagging as corrupt file which it clearly is not. Adobe please get this sorted it has been over a month now and is a serious impediment for business and personal users

same issue here, struggling with it for 1 month now... on my colleague's mac the feature is still working, he is using macOS Seqouia 15.5 while I am using macOS Tahoe 26.1... so when will Adobe implement the updates for the new macOS versions?

Same problem! Adobe, it is more than 2 months since the issue is brought to your attention and no clear answer from you how to fix it. Shame on you
