FAQ
Q. How much can it enlarge?
Up to 4x. The AI reconstructs detail, so it's far sharper than a simple resize.
Q. Are my images sent to a server?
Upscaling briefly routes through a server for processing, but once the job is done nothing is stored and it's deleted immediately.
Q. Why is it slow the first time?
On the first run it takes time to get the AI model ready. After that, processing is faster.
