AVIF (AV1 Image File Format) is the newest major image format on the web. Built on the AV1 video codec, it achieves compression efficiency that JPG and WebP cannot match. Switching to AVIF can cut image file sizes by 40–50% compared to JPEG at equivalent quality — a meaningful improvement for image-heavy websites.
AVIF vs WebP: AVIF is typically 20% smaller than WebP at the same quality. Both support transparency. WebP has broader legacy browser support; AVIF is the better choice for audiences on modern browsers (Chrome, Firefox, and Safari all support displaying AVIF).
Works in all browsers: Conversion runs on our server using Sharp, a high-performance Node.js image library. There are no browser-side encoding restrictions — Firefox, Safari, and Chrome all produce identical AVIF output.
Serving AVIF on your website: Use a <picture> element with AVIF as the primary source and a JPG or WebP fallback for browsers that don't yet support AVIF display.
