Frequently Asked Questions

Is my photo uploaded?

No. The AI model downloads to your browser the first time (about 5 MB) and then runs on your own device, so your photo never reaches a server.

Which AI model does it use?

Real-ESRGAN (realesr-general-x4v3), an open-source super-resolution model. It uses your graphics card through WebGPU where the browser supports it, and your processor otherwise.

How large can the result be?

Up to 7680 pixels on the longest side, which is 8K. A larger result is limited to that size and the page tells you.

Why does it take a while?

The picture is enhanced piece by piece on your own device. It is much faster on a computer with WebGPU than on an older phone.
