A few things to know

Does this upload my image or use a free try?

No. The model runs locally in a Web Worker, free and unlimited, without signup, upload, Turnstile or a daily quota. The first-use download size and model license appear before downloading. Models are cached for offline use and can be cleared.

What should I check before saving?

Upscaling may invent fine detail. Choose 2× or 4×; safe output limits depend on device memory.

Can I use Upscale image now?

Upscale image is available now, free and without signup. Processing happens entirely on your device.

Where will Upscale image process my files?

Files are read, processed and rendered in browser Web Workers. Nothing is uploaded. Cancel stops the worker immediately; originals remain unchanged.

Will Upscale image be free?

Yes. Free and unlimited on your device, without signup, uploads, Turnstile or daily quotas. One JPG, PNG or WebP up to 50 MB and 12 megapixels at a time; output guards limit decoded memory. A disclosed local model download is needed on first use.
