AVIF has pixel-based lossless. AVIF's pixel-based lossless seems not very exciting at first look since it performs worse than WebP lossless. https://www.reddit.com/r/jpegxl/comments/fjddrr/lossless_ima...

AVIF does not support recompression of JPEG files like Lepton, Brunsli, PackJPG, 7zip media layer (using Brunsli), and JPEG XL. AVIF works very well in the high density low-bit-rate compression. The flip side there is loss of detail.
