Frequently Asked Questions

Does this image converter work on Windows, Mac, and mobile?

Yes! Universal Image Converter is 100% in-browser. It works seamlessly across Windows, macOS, Linux, iOS (iPhone & iPad), and Android with zero installation or subscription fees.

Are my images uploaded to any remote server?

Never. All image rendering and compression takes place locally in your device's browser memory using modern HTML5 Canvas technology. Your photos are never uploaded or stored anywhere.
