What it is

Waifu2x-Extension-GUI is a portable Windows desktop application for enlarging images, animated media, and videos with AI super-resolution. It processes images, animated GIF, APNG, WebP, and video, supports batch jobs, and can enlarge up to 4x. Video frame interpolation is included for creating additional frames. Built-in super-resolution engines include Waifu2x, SRMD, RealSR, Real-ESRGAN, Real-CUGAN, Anime4K, ACNet, and RTX Super Resolution; interpolation options include RIFE, CAIN, DAIN, and IFRNet. The application supports AMD, Nvidia, and Intel GPUs, including multi-GPU processing for its built-in engines. Its portable workflow is to unzip the Windows x64 package and start it, with presets for one-click setting changes. Multithread controls and customizable settings support workflow automation. The project lists English, Simplified Chinese, Traditional Chinese, Japanese, and Spanish. It says no data is uploaded or collected and no server is used, though internet access checks updates and refreshes the donation QR code. Personal use is free; commercial use requires Patreon Premium from $4.99 a month.
