Waifu2x-Extension-GUI is a desktop application for Windows that uses machine learning (AI) to upscale and improve the quality of images, GIFs, and videos. Upscaling, also called super-resolution, means increasing the size and sharpness of a file beyond what the original pixels contain, using AI to intelligently fill in detail rather than just stretching the image. The app also supports frame interpolation for video, which means it can add extra frames between existing ones to make motion look smoother. The tool bundles multiple AI algorithms and engines in one graphical interface, covering both 2D anime-style content and real-life photos and videos. The built-in algorithms include Waifu2x, Real-ESRGAN, Real-CUGAN, Anime4K, SRMD, RealSR, and RTX Video Super Resolution (for Nvidia RTX GPUs), among others. Frame interpolation engines include RIFE, CAIN, DAIN, and IFRNet. You don't need to know which algorithm to pick, the app includes one-click settings presets. It supports AMD, Nvidia, and Intel GPUs and can use multiple GPUs simultaneously. Usage is designed to be simple: download, unzip, and run. You drop in your files, choose a preset or tweak settings, and the app handles the rest. It processes images, animated GIFs, animated PNGs, WebP files, and videos. The software is free for personal use; a premium version with additional features is available via Patreon. It is written in C++ and runs on 64-bit Windows.
