JPG to PNG - Convert JPG Images to Lossless PNG Free

Upload your JPG file and the tool converts it in your browser. The PNG keeps the original quality with no compression artifacts.

Yes. It is free forever with no signup, no watermarks, and no limits on conversions.

Yes. The tool works in any modern mobile browser, and your files never leave your device.

PNG uses lossless compression, so it keeps every detail. The file is bigger because nothing is thrown away.

No. Conversion runs entirely in your browser, so your files never leave your device.

Yes, JPEG and JPG are the same format with different extension spellings, so both convert in exactly the same way. Your photo becomes a lossless PNG copy that preserves every pixel the JPG currently holds. Nothing is sharpened or restored, because conversion cannot invent detail that is not there.

Every time a JPG is saved again it loses a little more quality, while PNG saves stay completely lossless. Converting to PNG first gives editors like Photoshop alternatives and design apps a stable file to work on. Your edits then remain crisp through repeated saves and exports.

A JPG has no transparency information to carry over, so the PNG simply keeps the same solid pixels. PNG only supports transparency when the source image actually contains see-through areas. To remove a background you need a dedicated background removal step, which is a different process entirely.

PNG stores image data losslessly, which is far less compact than the lossy compression JPG uses for photos. Large photo PNGs of several megabytes are completely normal and do not mean anything went wrong. If you later need a smaller file for sharing, convert back to JPG or compress the PNG.

It helps when you need exact pixels for editing, overlays, screenshots with annotations, or graphics that will be saved many times. It also helps when a design tool or client specifically requires a PNG file. For everyday photo sharing, the original smaller JPG usually remains the more practical choice.
