AVIF

AV1 Image File Format

AVIF uses AV1 video compression for still images and beats WebP and JPEG substantially at low bitrates, with HDR and wide-gamut support. Browser support is now broad; support in desktop applications is still patchy.

Extension: .avif
MIME type: image/avif

Opening a .avif file

If you landed here because something handed you a .avif file and nothing on your machine will open it, converting it to a format you already have a reader for is usually faster than installing new software. Every conversion above runs in this browser — the file is not uploaded, so it works on a locked-down work machine and on a file you are not allowed to send anywhere.
