Enhance any low-resolution image with AI

Swin2SR turns a thumbnail into a usable image.

If someone sent you a tiny image attachment or you're working from a low-res social media download, Quick Fix can 2× or 4× it up to a usable resolution with believable detail.

Upscale 2× or 4× with the Swin2SR open-source model

Upscale factor

Input is capped at 4 megapixels on CPU to keep runtime reasonable. Output will be 2× the (possibly downscaled) input.

Email me when it's done

Useful since 4× can take a few minutes on CPU.
