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.
Image Upscaler keeps the job narrow: sharper, larger images straight from your browser's own compute. It is built for the small but frequent moments when opening a heavyweight editor, installing a package, or uploading sensitive work to a random service is more friction than the task deserves.
