Both WebP and AVIF are modern, next-generation image formats designed specifically to replace JPG and PNG on the web. They both support lossy/lossless compression and alpha transparency. However, AVIF offers a significant step up in compression quality.
| Feature | WebP | AVIF |
|---|---|---|
| Codec Base | VP8 Video Codec | AV1 Video Codec |
| Average Compression Saving | 30% compared to JPG/PNG | 50%+ compared to JPG/PNG |
| HDR Support | No (8-bit depth limit) | Yes (10-bit & 12-bit depth) |
| Browser Compatibility | Universal (97%+) | 93%+ (Safari support added recently) |
When to choose AVIF
Choose AVIF for static photos, hero headers, and detailed graphics on modern websites where you want to minimize byte size down to the absolute limit. AVIF delivers noticeably cleaner images than WebP at identical file weights.
When to choose WebP
Choose WebP if you want maximum safety and compatibility across slightly older browsers, or when rendering animated files that need to load faster than standard GIFs.
