Where does the image upscaling process happen?

All upscaling runs locally in your browser on your device. Images are not uploaded to a server, stored, or shared, so the process stays private.

How much can I upscale an image?

This tool supports 2x–5x and 125%–500% presets, plus a custom scale up to 10x (1000%). Very large outputs may be limited by your browser canvas size.

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.
