You crop your image directly in your browser. The tool runs locally, so nothing gets uploaded to a server. Just open your image, adjust it the way you want, and download the edited version instantly.
2. Is it safe to blur images online?
Yes. The tool handles your file inside your browser only, without sending it anywhere. You stay in full control of your image, and no data leaves your device.
