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.
