About this converter

AVIF is the most efficient image format available in 2026. It typically produces files 30-50% smaller than JPEG at the same perceived quality, thanks to the AV1 video codec it is built on. This converter loads your JPG, draws it to a Canvas element, and encodes it as AVIF using your browser's built-in encoder via canvas.toBlob('image/avif'). No libraries needed, no server involved. Your image stays on your device the entire time.
