> In lossy mode I think there is no difference between AVIF, HEIC or JXL. AVIF is even a little bit ahead.
AVIF is definitely not ahead for the high quality levels you'd use in photography. AVIF is ahead at lower quality levels.
> For lossless mode, JXL's fast modes (-e1 and -e2) are fast. But their compression ratio is terrible.
JXL lossless e1 is still a lot better than the lossless compression people tend to use for photos these days. Like Apple has been using Lossless JPEG, which sucks.
Agreed. At camera quality jpeg xl is far ahead in quality. Apple's last announcement is about camera quality, close to lossless kind of lossy. In this domain jpeg xl does not have real competition. AVIF and HEIC don't even support more than 12 bits of dynamics, and become slow when quality is increased.
