About the AVIF to WebP Converter
AVIF often beats WebP on file size, but WebP has had broader support for longer — older Safari versions (before 16.4), many CMS plugins, email tools and editing apps handle WebP but not AVIF. WebP is the compatible-yet-compact middle ground.
The AVIF is decoded by your browser (Chrome 85+, Firefox 93+, Safari 16.4+), including its alpha channel.
The WebP is written by your browser's WebP encoder: lossy at the quality you choose, or effectively lossless at 100. Safari before version 17 can't encode WebP and falls back to PNG — the result card tells you if that happens.

Things to know
- Double lossy step. Converting a lossy AVIF to lossy WebP compresses twice; keep quality around 85% to avoid visible artefacts.
- HDR is lost. WebP is 8-bit, so HDR AVIFs are tone-mapped.
