Convert JPG to PNG Online

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

JPEG photos are great for sharing, but they don't support transparency and lose a little quality every time they're re-saved. Converting to PNG gives you a lossless image you can place over any background — ideal for logos, screenshots, and graphics cut out of photos. This converter runs entirely in your browser, so your files never leave your device.

How it works

  1. 1

    Drop your JPG file

    Drag a JPEG image into the box, or click to browse. Nothing is uploaded — the file stays on your device.

  2. 2

    Convert to PNG

    Click Convert. The image is decoded and re-encoded as a lossless PNG locally in your browser.

  3. 3

    Download the result

    Save the PNG with one click, or drop another file to convert it — no limits, no sign-up.
