Waifu2x-Extension-GUI is a free, open-source desktop AI upscaling program widely regarded as one of the best local tools for enhancing anime-style art, general images, GIFs, and videos. Originally created to provide a graphical interface for complex command-line processes, it bundles multiple leading open-source neural network engines to process multimedia files entirely on your local hardware. Key Features and Performance
All-in-One AI Engine Wrapper: It acts as a user-friendly front end integrating Waifu2x, Real-ESRGAN, Anime4K, and SRMD.
Multimedia Support: Upscales standalone images, animated GIFs, APNG, WebP, and full-length videos simultaneously.
