Upscayl

What it does

Upscayl is a free, open-source desktop app that upscales images locally using your GPU. For sensitive product designs that must never leave the building, it is the zero-leak option.

Models are swappable for different material types — fabric, metal, text. The trade-off is speed and setup compared with cloud services.
