Good question actually. Some people ask if AVIF format is better now, since it compress even smaller than WebP. And technically, yes AVIF can be smaller in some cases.

But WebP still wins in terms of Compatibility and Encoding speed. AVIF takes longer to encode and not all tools support it fully yet. For most website owners, WebP remain the safer and more practical choice right now.
