How AVIF compares to WebP

AVIF is generally similar in nature to WebP. The main differences are file size, quality characteristics, and transparency support.

Quality recommendations

For AVIF output, start at the balanced preset and adjust to taste. A lower quality setting shrinks the file further; a higher one keeps more detail. Keep the original WebP file for archival edits.

Is conversion private?

WebP is re-encoded to AVIF in a local web worker. Your image stays on your device.

Frequently asked questions

Is AVIF always smaller than WebP?

Usually yes for photos, though AVIF encoding takes longer. For graphics with flat colors the saving can be smaller.

Should I serve AVIF or WebP on my site

Serve AVIF for modern browsers for the smallest files and keep WebP as fallback for older browsers that do not support AVIF.

Will converting WebP to AVIF lose quality

A small loss occurs because AVIF recompresses lossy WebP. Use balanced quality and keep the original WebP as master.

Will converting to AVIF degrade quality?

Every AVIF re-encode discards a little detail. Keep your original file if you might re-edit it later.
