How auto-detection works

  1. 1
    Drop any image
    HEIC, WebP, AVIF, GIF, BMP, JPG, PNG, the lot. We read the first few bytes to identify the format.
  2. 2
    Convert on your device
    Your browser does the conversion locally. HEIC uses a tiny WASM decoder. Everything else uses the browser canvas.
  3. 3
    Download. Done.
    Save individual JPGs and PNGs, or grab the whole batch as a ZIP. Nothing is uploaded, nothing logged.

Your images stay on your device the entire time. Nothing is sent or stored anywhere.
