Acrobat on macOS 26.2 (Tahoe) reports ALL PNG/JPEG images as corrupted in Fill & Sign

Hello,

I would like to report a reproducible issue with Adobe Acrobat Reader (last version 2025.001.21184) on macOS 26.2 (Tahoe), using a Mac Mini M4.

 

Problem

When using Fill & Sign → Add Signature → Image, Acrobat reports that the selected PNG image file is corrupted.

 

This happens with:

  • PNG files

  • JPEG files

  • Brand new screenshots created directly on macOS 26.2

  • Images converted with Preview

  • Images converted with ImageMagick

  • Images converted with XnConvert

  • Images with sRGB IEC61966-2.1 profile

  • Images with no embedded color profile

All of them produce the same error: image corrupted.

 

Important observations

  • The exact same files work correctly on another Mac running macOS Sequoia with the same Acrobat Reader version.

  • Typed or drawn signatures inside Acrobat work normally.

  • GPU acceleration was disabled via:

defaults write com.adobe.Acrobat.Pro DCEnableGPUAcceleration -bool false
defaults write com.adobe.Acrobat.Pro EnableHardwareAcceleration -bool false

 

 

This suggests a possible incompatibility between Acrobat’s image import module and macOS 26.2 image decoding APIs.

 

Can anyone on macOS 26.2 confirm this behavior?

 

Thank you.

Alessandro

      Hope you are doing well, sorry for the trouble and thanks for sharing such a detailed observation.

       

      Would you mind sharing a small video recording of the steps you are taking and the issue as it occurs so we can get this checked further by our engineering team?

      Hi Amal,

      sure, in attach a quick video of what happens with any image file (even simple screenshots done on macOS Tahoe). As said, with macOS Sequoia no issues at all.

      In both cases I’m using Adobe Acrobat Reader (last version 2025.001.21184)

       

      Let’s keep in touch if you get any news from your technical team !

       

      Thanks a lot

      Alessandro
