About this tool
Convert JPG or JPEG files to PNG on your own device. PNG is lossless, so the conversion introduces no further quality loss — though it cannot undo the compression already baked into the original JPG. Useful when you need a format that supports transparency, or when a tool or platform specifically requires PNG.
The honest advice: most of the time you do not need this conversion. If you are trying to make a file smaller, PNG is the wrong direction for photographs — use the image compressor with WebP output instead.
Convert to PNG when something genuinely requires it: a platform that rejects JPG, a print workflow that wants lossless input, or a logo you are about to cut a transparent background into.
