@Jain I say with near certainty there will be an AV2F, a VIC (VVC-derived image format), and maybe even a WebP v2 in the next 5 years. None will be nearly as promising as JPEG-XL is at this very moment. AVIF is a good image format, but has crippling limitations that JXL will simply never have and that AVIF successors will not desire to fix. The "best" image format isn't just the one with the best lossy compression.
