Convert JPG to AVIF Online

Runs 100% in your browser — your files never leave your device.

AVIF routinely beats both JPEG and WebP on size at equal quality — the best compression of any format browsers display. If your browser can encode AVIF (Chrome and friends), this tool produces it locally; otherwise it tells you plainly rather than failing silently.

How it works

  1. 1

    Drop your JPG file

    Drag a JPEG into the box, or click to browse. Nothing is uploaded.

  2. 2

    Convert to AVIF

    The photo is encoded as AVIF if your browser supports it.

  3. 3

    Download the result

    Save the AVIF with one click, or drop another file to convert.
