It got me drooling for JPEG XL like I never did for WebP or HEIC.

impressive:

Lossless JPEG Re-compression

An incredibly unique JPEG-XL feature that no other codec can currently offer competition to is lossless JPEG re-compression, or the ability to take a JPEG input and provide an output with a smaller filesize (on average, 20% smaller) that is pixel-for-pixel identical. This is why companies like Meta have endorsed JPEG-XL, as it offers a path forward for the existing JPEGs on the Internet.

Apple really gave JXL the boost it needed. A part of me deep inside hopes that Apple switches to JXL & leapfrogs the whole gain map JPEG thing going on in Android land currently, then Android OEMs can switch to JXL too. HEIC is not & will never be compatible enough, and the royalties ruin it.

Bring it on! JPEG XL is now supported natively in macos sonoma, which is pretty nice. When it comes to lossless compression, it always (in my own cases) produces smaller files than png by a significant margin.
