This JPG to PNG converter runs locally, using your own browser. Your files are never uploaded to a server, so they stay on your device from start to finish.
- Are my JPG files uploaded to a server?
- No. The JPG to PNG conversion runs locally in your browser using your own device's CPU. Your files are never uploaded, never transmitted over the network and never stored on a server.
- Is there a file size limit for JPG to PNG?
- There is no imposed limit, because nothing is uploaded. The practical ceiling is your device's available memory, so very large files may be slower on older hardware.

- Yes. Once the page has loaded, converting JPG to PNG keeps working without a network connection, since the conversion happens entirely on your device.
- Do I need to sign up or install anything?
- No. There is no sign-up, no account and no software to install. Pick a JPG file and convert it to PNG straight away.
- Is converting JPG to PNG free?
- Yes, it is free to use, with no watermarks and no daily quota.
