AVIF is the new heavyweight champion of image compression: roughly 50% smaller than JPG at equal quality, with HDR and wide-color support. Convert your JPGs here in the browser: supported in current Chrome, Edge, and Firefox; Safari 16+.
Going straight from JPG to AVIF is the biggest single size cut available to an ordinary photo, because AVIF's codec is generations ahead of JPG's. On top of the roughly halved file size, AVIF can carry wider colour and higher bit depth than JPG ever could, so it is a genuine upgrade for a modern web audience rather than just a smaller copy.

When to reach for AVIF
This is the format for large, important, frequently-served images, hero banners and rich product photography, where halving every byte translates into real load-time and bandwidth wins. If you control the environment and it supports AVIF, converting these is one of the highest-impact optimisations you can make.
The costs are encode time and reach: AVIF takes noticeably longer to encode than WebP, a real few seconds on big batches, and although all current browsers decode it, some older webviews and CMS pipelines still stumble. For a broad or uncertain audience WebP remains the pragmatic default, so treat AVIF as the choice for maximum compression when you know the destination can handle it.
Frequently asked questions
What is AVIF exactly?
AV1 Image File Format, an image encoding based on the AV1 video codec. It achieves the best compression of any mainstream image format today: about half the size of JPG and 20% under WebP at comparable quality.
Which browsers support AVIF?
Chrome 85+, Edge, Firefox 93+, Opera, and Safari 16+ (macOS Ventura and iOS 16 era). That covers effectively all traffic in 2026, but AVIF support is absent in older Safari and some embedded webviews. Check your audience.
Why not always use AVIF then?
Encoding is slower than WebP (seconds vs near-instant on big batches), and a few ecosystems (notably older iOS devices and some CMS pipelines) still stumble on it. WebP remains the pragmatic default; AVIF shines for large hero images where bytes matter most.
