FAQ

How does the AI upscaler make images bigger without getting blurry?

It uses a neural super-resolution model that reconstructs detail as it scales, so edges stay sharp instead of turning into soft, pixelated blocks like a normal resize.

Is my image uploaded to a server?

No. The AI model runs entirely in your browser on your own device, so your image never leaves your computer.

How much can I upscale by?

Up to 4x the original width and height. A 500x500 image becomes 2000x2000. Very large images are processed in tiles so your browser doesn't run out of memory.

Why does the first run take a moment?

The AI model downloads and warms up the first time you use the tool. After that it is cached and much faster.
