    About JPG → AVIF

    JPG and AVIF are both common image formats. JPG originated as a photo format; AVIF is the newest format and offers the best compression-vs-quality ratio of any widely-supported format today.

    This tool decodes JPG input using the browser's image decoder, redraws it onto a 2D Canvas, then re-encodes via canvas.toBlob() in the target format. No server roundtrip, no upload, no watermark.
