FAQ
Is it really free?
Yes. It uses an open-source AI model that runs in your browser. No signup, no watermark.
Are my photos uploaded?
No. The AI runs on your device. Your photo never leaves your browser.
Why is it slow or failing on big images?
Upscaling is heavy AI work done on your device. Very large images can exhaust browser memory. Images under ~1500px on the long edge work best.
First run is slow, why?
It downloads the AI model once, then caches it for next time.
