Hi forum!
I hope I am welcome here!
My favorite tool metadata cleaner got abandoned so I am looking for new tool
I am using Linux Mint for like a year now, but I am still looking for GUI since terminal for me is dark forest.
Hi, PG has some good recommendations for this purpose
Don’t let anyone let you think you’re not welcome here. Everyone is.
But research this forum more, you’ll find answers.

This hasn’t been updated in 5 years. 
If you prefer to use a web interface instead of installing an app, MAT2 (a PG-recommended tool) has a web version.
Upload it to Signal, it’ll strip the metadata.

Does this work for all file types or just photos?
Flatpack app Scramble, I like it.
Haven’t tried with other files than photos but EXIFtools can probably be a quick test to double-check if it works for other ones too. 
It’s important to note that the git says
“This is an online version of mat2. Keep in mind that this is a beta version, don’t rely on it for anything serious, yet.”

Wow. I had suspected but wasn’t sure. Is there official documentation on which file types are supported?
I mostly found:
- this tweet
- this independent testing
- quite some discussions on Github about overall EXIF data here and there
- some discussions here on the forum, confirming it too
TLDR: no official blogpost with all the files + details about the metadata being stripped itself.
You could look into the current codebase on Github if you’d like some proof but overall:
- use Signal for a quick and simple stripping
- use one of the recommended tools by PG for some safer and more thorough stripping for critical files

See
Linux Mint
And another way to use addon for Nemo
But i would replace zenity with:
Exec=sh -c 'mat2 %F && notify-send "Metadata successfully cleaned." "Cleaning Complete" || notify-send "An error occurred during cleaning." "Cleaning Failed"'
To use native informing without installation a new.
