Frequently asked questions
How much can I upscale?
2× or 4×. The AI reconstructs detail as it enlarges, so results look sharper than a plain resize.
Is it free and private?
Yes — no account, no credits, no watermark, and your image is never uploaded. The model runs in your browser.
Why is it slow on big images?
Upscaling is compute-heavy and runs on your device. Large photos take longer and use more memory; smaller images are quick.
What's the first-run delay?
The AI model (tens of MB) downloads once, then is cached for instant use next time.
