02 · The honest pitch

Why Image Upscaler?

Online upscalers usually upload your photo, watermark the result, or charge per image. This one runs the Swin2SR super-resolution model in your browser via WebAssembly — your photo never leaves your device, the result is yours, and there is no quota. Best suited to images up to about 1024px on the long side; larger inputs are scaled down first to keep it fast.

Frequently asked questions

No. The AI model is downloaded to your browser once, and all inference happens on your device. Your image is never transmitted.
