Description
Cupscale provides a user-friendly interface for AI-powered image upscaling. It uses ESRGAN & Real-ESRGAN models to increase image resolution without losing details. Users can apply multiple models at once using Model Chaining, work with entire folders of images via Batch Upscaling, and even directly process images from the clipboard. It supports common image formats including PNG, JPEG, BMP, WEBP, TGA, and DDS.
The software also offers pre-processing to downscale low-resolution images before upscaling, automatic image tiling to avoid VRAM overflow, and post-processing to resize images after enhancement. Its GPU compatibility ensures faster processing, while CPU fallback allows functionality on systems without dedicated GPUs.
Cupscale’s versatility, ease of use, & open-source nature make it an excellent choice for designers, photographers, & gamers looking for high-quality AI image enhancement for free.
