What's up with added EXIF data by gThumb ?

  • Make a screen shot of your desktop
  • Check with a viewer and see no EXIF data
  • Load it in gThumb to use its crop feature, crop and save
  • Check again with a viewer and see that gThumb added EXIF data including the gThumb version

In the mean time I've started to use other software to crop screen shots but I am still puzzled why gThumb always adds EXIF data ?

My favorite general image viewer is nomacs.

Go to Preferences>Extensions. there is an extension for EXIF support. turn it off and then try again and see if the same thing happens

There's also a plugin that scrubs metadata. But you have to use it manually from the tool menu.

I just used gThumb recently to try to post something I had inverted, but posting it to sopuli/lemmy scrubbs the exif data and it was posted as if I didn't do anything.

So, gThumb uses exif data to modify pictures which is likely what is added.

*What alternative are you using?

Yes, uploading to Mastodon and Lemmy will likely automatically wipe EXIF data by those sites.

For image cropping I've switched to Gwenview which I'm pleased with.
