AVIF and WebP are both web-native formats, but WebP has been supported in every major browser since 2020 (Safari 14) while AVIF only reached Safari in 16.4. Converting gives you a file that older browsers and more tools accept, at a size still well below JPEG.
Your browser decodes the AVIF and encodes WebP at quality 92. Transparency is preserved; the WebP is usually somewhat larger than the AVIF and about a third smaller than the equivalent JPG.
If every viewer is on a current browser, AVIF is still the smaller file and serving both with a picture element is the standard approach. Convert to WebP when a CMS, a plugin or a design tool refuses AVIF, or when you need one file that works everywhere.
