Cross-platform has never been easier than ever

JXL encoder is just very unoptimized, so lossy screenshot is currently pretty bad

Yes, with all metadata preserved. The converted JXL even has checksum metadata for verification

It's a lossless conversion while still saving spaces. You can even convert back to get the exact same file bit-perfect

Decoding support is pretty poor though. JXL decoder are much more friendly beyond 16K

AVIF doesn't work that great either. Let's just switch to AV1 video. AVIF animated still really buggy compared to the video itself

This is not jixel though. It was their own encoder

This is awesome. Thanks for sharing

Current encoder regressed a lot on lossy images compared to 0.7 era. There will be works done to fix this in near future

Definitely possible. The reference encoder has a lot of room to improve. Even for lossless there are things to improve too
