Frequently asked questions
Are my images uploaded to a server?
No. Supported image processing runs locally in your browser. Third-party decoder code may be loaded only when a format needs it, but your image itself stays on your device.
Do I need an account?
No. The current ViewerPix tools work without registration.
Does this work on mobile?
Yes. The interface is responsive, although very large images can be limited by the memory available in the browser.
