AVIF converter
AVIF gives you the smallest files of any format on this site, which is exactly why you sometimes need to leave it: the rest of the software world is still catching up. Use the pairs below to publish AVIF for modern browsers or to unwrap an .avif somebody sent you into something your tools accept.
What is AVIF?
AVIF (AV1 Image File Format) is the newest mainstream image format, published by the Alliance for Open Media in 2019 on top of the royalty-free AV1 codec. It delivers the strongest compression of any widely deployed format, especially at low and medium quality, and adds an alpha channel, HDR and 10/12-bit color. Browser support landed in Chrome 85, Firefox 93 and Safari 16, but much desktop software still cannot open an .avif file.
