Image to AVIF Converter

AVIF, the AV1 Image File Format, is the newest heavyweight in image compression. Released in 2019 by the Alliance for Open Media, it is built on the same AV1 video codec that powers modern streaming, and it consistently produces the smallest files of any mainstream format at a given quality. On top of that efficiency it brings genuinely modern features: 10 and 12-bit colour depth, high dynamic range, wide colour gamut and full alpha transparency, all royalty free.

Converting images to AVIF is about squeezing the absolute most out of every byte. An AVIF can often be half the size of a comparable JPEG while looking cleaner, with fewer banding and blocking artifacts in skies and gradients. That makes it ideal for image-heavy websites, hero banners and galleries where bandwidth and load time really count. Browser support is now broad across Chrome, Edge, Firefox and Safari, though for the occasional legacy environment it is wise to keep a WebP or JPEG fallback alongside your AVIF files.

This bulk AVIF converter encodes JPG, PNG, WebP, HEIC and more into next-generation AVIF directly in your browser, with no signup, no watermark and no files left sitting on a server. Convert one image or many at once and download them individually or as a single ZIP. For a future-proof setup, serve AVIF first, WebP second and JPEG or PNG as the final safety net.
