Waifu2x-Extension-GUI review
A capable free Windows upscaler for images, animations, and videos.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Waifu2x-Extension-GUI is a portable Windows x64 desktop application for enlarging images, animated GIFs, APNGs, WebP files, and videos. It is suited to users who want one free personal-use tool for varied media types, including animated content and video. The application also offers customizable processing settings and video frame interpolation, making it more suitable for mixed media workflows than an image-only utility.
Its strongest area is processing depth. The software includes multiple neural-network super-resolution algorithms, including Waifu2x, Real-ESRGAN, Real-CUGAN, SRMD, RealSR, Anime4K, and RTX Video Super Resolution. Denoising adds another control for image processing, while batch processing helps handle multiple files. Multi-threading and multi-GPU workflows are available for users with compatible hardware. Animated GIF, APNG, and WebP processing further broaden its desktop use beyond still images.
The published licensing terms make the free version available for personal use, while commercial use requires a separate premium license. The application is limited to Windows x64, and its maximum scale is 4×, so it is a better fit for Windows users with moderate enlargement needs than for people seeking broader platform coverage or larger scaling options. Choose it for free personal media upscaling, animation processing, interpolation, and configurable local workflows; choose another tool if macOS or another operating system is required.
