JPG to PNG converter

Turn JPEG files into PNG without uploading them: the browser decodes each JPG and writes a new PNG on your device. PNG is lossless, so later edits and re-saves never add artefacts, and it keeps transparent backgrounds.

Questions

Is converting JPG to PNG free?

Yes. Conversion runs in your browser on every plan, with no account, no watermark and batches of up to 200 files.

Are my JPG files uploaded?

No. The browser decodes each file and encodes the new one on your device. Nothing is sent to a server.

Does converting JPG to PNG lose quality?

No further loss: PNG stores every pixel exactly. It cannot bring back detail an earlier lossy save removed, and the file is often larger than the original.

Can I make the PNG bigger at the same time?

Converting keeps the pixel size. To enlarge, run the upscaler afterwards: 2× is free and also runs on your device.
