Converting WEBP to AVIF pushes compression even further. AVIF, based on the AV1 codec, usually produces smaller files than WEBP at matching quality, with the same support for transparency and animation. It is worth it when every kilobyte counts, as long as you keep WEBP as the fallback for clients that cannot read AVIF yet.
Typical result: modestly smaller than the WEBP at similar quality.
