I wanna use JXL locally. It’s quite amazing technologically, you can losslessly compress a JPEG to 0.8 or so of the original size.

I compress my photos for long-term storage anyway, so why not do it with JXL.

Thanks for the app recommendation!

(Fossify is a fork of the discontinued SimpleMobileTools.)

Personally, I’ve found Fossify Gallery so far: https://f-droid.org/packages/org.fossify.gallery/ Tried it out, it works well. Any other recommendations would be nice, too.

Signal, for example, does not support JXL as of today. But saving the photo and opening in Fossify Gallery works.

I think a more fair name should be OnlyOffice. Wrapped in CryptPad for privacy and encryption. I’d also note a level of controversy around OnlyOffice, it being (still) developed in Russia, not making “we support Ukraine” / “we condemn the war” statements. There’s a bit more of that not just about the war, too.

And also to be fair, the product itself is visually quite decent, especially if you’re looking for online collaboration.
