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.
