Why convert JPG to PNG?

JPGs are compressed every time they're saved, which means each re-save loses a little quality. PNG uses lossless compression — the file is bigger, but every pixel survives every round trip.

Convert JPG to PNG when you need to layer the image into a design, add transparency later, or stop the compression cycle from chipping away at your photo. Note: the original JPG's lost detail won't come back — PNG just stops it from getting worse.

Are my files uploaded anywhere?

No. Conversion runs in your browser using JavaScript and the Canvas API. Your files never leave your device. You can disconnect from the internet after this page loads and the tool will still work — try it and see.
