JPG to PNG Converter: limits and things worth knowing

• Converting to PNG does not recover quality. JPEG compression artefacts are already baked into the pixels, and PNG simply stores them losslessly — it prevents further loss rather than undoing past loss.
• The file will get bigger, often by several times, because PNG cannot compress photographic detail nearly as efficiently as JPEG.
• The result has an alpha channel available but is fully opaque; you still need an editor to actually cut out a background.
• This conversion is worth doing before a series of edits, and not worth doing for storage or delivery.

Is it private and secure?

Your privacy is built in. JPG 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.
