JFIF to PNG Converter: limits and things worth knowing

• JFIF is simply JPEG under a different extension, so this is a genuine JPEG-to-PNG conversion with all the same trade-offs: no quality is recovered, and the file grows.
• Existing JPEG artefacts are preserved losslessly rather than removed.
• If you only need the file to open normally, converting to JPG is the smaller and more appropriate choice.

Is it private and secure?

Your privacy is built in. JFIF to PNG Converter does all processing on your own device using client-side code, so your files are never transmitted, stored or seen by anyone — including us.

Network activity: none. Nothing is sent and nothing is fetched. This tool makes no network request at all once the page has loaded — which is why it keeps working if your connection drops.

You do not have to take that on trust — our privacy proof page publishes the Content-Security-Policy that enforces it, lists every third party it permits, and shows how to verify the whole claim yourself.
