What is AVIF?
AVIF stores images compressed with the royalty-free AV1 codec from the Alliance for Open Media. It supports lossy and lossless compression, transparency, high bit depth and HDR.
For photographs AVIF often reaches similar quality to JPEG at roughly half the file size, and it handles gradients with less banding than WebP.
When to use AVIF
- Photos and hero images on modern websites
- HDR and wide-color images
- Reducing bandwidth on image-heavy pages
Limitations
- Encoding is slower than JPEG or WebP
- Support in older software and some upload forms is still missing
Compatibility
Supported by current Chrome, Edge, Firefox and Safari (Safari 16.4 and later).
Compared with other formats
- WebP: WebP encodes faster and is supported slightly more widely.
