HEIC to AVIF, free forever.
The most efficient image format on the web. Half the size of JPG at the same visual quality. Right in your browser — nothing uploads.
⚠ Browser requirement
AVIF encoding in the browser requires Chrome 124+ or Edge 124+ (April 2024). Firefox and Safari can show AVIF images but can't yet encode them. On those browsers, the AVIF button will be disabled — pick WebP instead.

- Smallest files by far — typically 50% smaller than JPG, 20-30% smaller than WebP, at the same visual quality.
- Built on AV1 — the codec Netflix, YouTube, and Vimeo use for video. Royalty-free, open standard.
- Display support is now universal — every modern browser can show AVIF (Chrome 85+, Firefox 93+, Safari 16+, Edge 121+).
- HDR-ready — AVIF supports 10-bit and 12-bit color, so your iPhone HDR photos look the way they're supposed to look.
AVIF vs WebP vs JPG — pick by use case
| Use case | Best pick |
|---|---|
| Sharing on WhatsApp / iMessage / Email | JPG |
| Posting on a website or blog | AVIF (best) |
| Cross-browser web image (no AVIF fallback) | WebP |
| Printing | JPG or PNG |
| Editing in Photoshop / Pixelmator | PNG (lossless) |
Why is AVIF encoding slower than JPG?
AVIF squeezes more out of each byte by doing more computational work per pixel — analyzing neighboring blocks, predicting from motion vectors (yes, image AVIF uses video-codec tricks). On a typical 12 MP iPhone photo, expect 1-2 seconds per file vs ~200ms for JPG. The output is worth it: half the file size for the same visual quality.
Is it really free?
