Is this an AI upscaler?

No. This is a fast browser-based scaler using high-quality image smoothing, not AI reconstruction.

Are images uploaded to a server?

No. Upscaling happens locally in your browser.

Is this online image upscaler safe to use?

Yes. Your images are processed entirely in your browser and are not uploaded to our servers, stored, or shared. This keeps your files private on your device.
