Image conversion

Convert JPG to PNG

Drop a JPG and get a lossless PNG back. The conversion runs entirely in your browser, so the image never leaves your device.

About JPG to PNG

PNG is lossless, so converting from JPG preserves the image exactly as it is, with no further compression artefacts. PNG also supports transparency and is a better fit for screenshots, logos, and graphics with sharp edges or text. Note that a JPG has already been compressed, so converting to PNG does not recover detail that was lost — it usually produces a larger file.

Is it private?

Yes. The converter is WebAssembly and browser APIs running on your own machine. Nothing is uploaded, stored, or seen by us — there is no server to send files to.

Frequently asked questions

Does converting JPG to PNG improve the quality?
No. A JPG has already been compressed, so converting to PNG cannot recover detail that was lost. PNG is lossless, so it preserves the JPG exactly as it is — usually in a larger file.
Are my images uploaded to a server?
No. The conversion runs on your device using WebAssembly and browser APIs. Your image is never sent anywhere, and the tool keeps working even if you go offline after the page loads.
Is it free, and do I need an account?
It is free with no watermarks, no daily caps, and no sign-up. Drop a file, convert it, and download the result.
When should I use PNG instead of JPG?
Use PNG for screenshots, logos, line art, and anything with text, sharp edges, or transparency. JPG is better for photographs, where a smaller file matters more than perfect fidelity.
