Frequently asked questions

Is my picture uploaded?

No. The AI model (about 55 MB) is downloaded once and then runs on your device. Your picture never leaves it.

Why does it take a while?

The AI works on your own computer, part by part. A small picture takes under a minute, a larger one several minutes, and a slower computer takes longer. A graphics card makes it much faster, and the tool uses it when it can. You see the time left while it works, and you can stop at any time.

How big can the picture be?

Up to about 1 megapixel (roughly 1,000 × 1,000 px), and the result can be at most 8,192 px on its longest side. For larger pictures, make them smaller first with the Image Resizer.

Does it add real detail?

The AI makes a sharp, believable guess based on what the picture shows. It cannot recover detail that is not there, so expect a cleaner and larger picture, not a different one.

Does it keep transparency?

Yes. PNG and WebP transparency is kept. A JPG is placed on a white background.
