    How it works

    1. Pick your file. It is read directly from your disk into browser memory.
    2. The decoder and encoder run as WebAssembly on your own CPU.
    3. The result is written back to your downloads folder. No network request is ever made.

    Why convert in the browser

    Nothing is uploaded

    Open your browser’s network inspector while converting. You will see zero outbound requests. Privacy here is structural, not a promise.

    No waiting on uploads

    A 40 MB photo would take a while to upload and come back. Locally it is done as fast as your machine can decode it.

    No accounts, no limits

    There is no server bill to cover, so there is no sign-up, no watermark, and no daily cap.
