Reference
In our benchmarks, AVIF produced the smallest files at comparable quality. Your results vary by photo.
| Format | Relative file size | Best for |

| WebP | ~25–35% smaller | Web with broad support |
| AVIF | ~50% smaller | Modern web, smallest files |
AVIF (AV1 Image File Format) compresses photographs far more efficiently than JPEG or WebP. At the same visual quality it can cut file size roughly in half, which means faster page loads and less bandwidth.
Use AVIF where browsers support it, and keep WebP or JPEG as a fallback. If your browser cannot encode AVIF yet, the tool tells you clearly instead of failing silently.
