JPG to PNG Converter: Free & Private
You need a clean edge, a flat background, or a file that survives repeated saving. Convert it here, in your browser, with nothing uploaded anywhere.
Why convert JPG to PNG?
Converting JPG to PNG does not undo the compression that has already happened, those artefacts are baked into the pixels. What it does give you is a lossless container from this point forward, which is exactly what you want before cropping, annotating, or dropping an image into a design tool that will re-export it several times.
The catch worth knowing about
PNG cannot invent transparency. If your JPG has a white background, the PNG will have a white background too, an opaque white rectangle, not an alpha channel. Removing that background is a separate editing job that no format conversion can do, and the background remover is the tool for it, which runs on your device like everything else here.
One tip before you start
Screenshots, logos, charts and diagrams that arrived as JPG benefit most here, because PNG's compression suits flat colour and text far better than photographic tone. Going the other way, PNG to JPG is what you want when a PNG has grown too large to send.

Screenshots, logos, charts and diagrams that arrived as JPG benefit most here, because PNG's compression suits flat colour and text far better than photographic tone. Going the other way, PNG to JPG is what you want when a PNG has grown too large to send.
Will I lose quality converting JPG to PNG?
No. PNG is lossless, so every pixel survives the conversion exactly. The file gets bigger in exchange, particularly for photographs.
Do my JPG files get uploaded?
No. The conversion runs on your device, in the browser tab you are reading this in. You can prove it: disconnect from the internet and convert anyway.
Is it free, and how many JPG files can I do at once?
Free, with no sign-up, no watermark and no daily limit. Up to 200 files per batch, downloadable individually or as one ZIP.
