Frequently Asked Questions
What is AVIF and why is it better than WebP for compression?
AVIF (AV1 Image File Format) is a next-generation codec derived from the AV1 video standard. It achieves 40–55% smaller files than JPEG and 15–25% smaller than WebP at equivalent visual quality. AVIF also supports HDR color, wide color gamut, and alpha transparency. Browser support covers Chrome 85+, Firefox 93+, and Safari 16+.
Is AVIF supported in all browsers?
AVIF is supported in Chrome 85+, Edge 121+, Firefox 93+, and Safari 16.4+. For broader compatibility, serve AVIF with a WebP fallback using the HTML <picture> element with <source type="image/avif"> and <source type="image/webp"> before the default <img>.
