Convert JPG to AVIF Online
Need to turn a JPG file into AVIF? JPG (also written JPEG) is the world's most widely supported photo format. It uses lossy compression that throws away detail the eye barely notices, which keeps photographic files small while staying compatible with virtually every device, browser and app. AVIF is a next-generation format based on the AV1 video codec. It delivers the smallest files of any common format at a given quality and supports HDR, transparency and wide colour, making it the cutting edge of web imagery. Converting from JPG to AVIF bridges the two: you keep the picture, but in a format that fits where you are taking it.

What to expect converting JPG to AVIF
AVIF is the smallest of the modern formats, often 40-50% smaller than the source JPG at the same quality.
Another lossy pass slightly alters pixels, but AVIF retains detail and gradients exceptionally well and adds transparency support.
You want maximum compression for fast pages and your audience uses current browsers.
Compatibility with older devices or apps is required, as AVIF support is still the newest.
