How AVIF compares to JPG

AVIF is generally similar in nature to JPG. 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 JPG file for archival edits.

Is conversion private?

AVIF encoding happens in a browser web worker with a codec loaded locally. Your photo is never uploaded.

Batch convert JPG to AVIF

Frequently asked questions

Is AVIF better than WebP?

AVIF generally compresses photos further than WebP at the same quality, though encoding is slower. For web use AVIF is the smallest choice.

Can all browsers display AVIF?

All modern browsers support AVIF. Older browsers and some email clients may need a JPG or WebP fallback.

Will converting JPG to AVIF look worse

Not at balanced quality. AVIF preserves detail well at smaller size. Keep the original JPG for editing and serve AVIF for delivery. See WebP vs AVIF for comparison.

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.
