What is this?
Waifu2x-Extension-GUI is a Windows desktop app that upscales (super-resolution) images, GIFs, and videos, and can also interpolate video frames, using a collection of AI engines like Waifu2x, Real-ESRGAN, Real-CUGAN, RIFE and DAIN.
Is this a GUI app or a command-line tool?
It's a standalone graphical Windows application with built-in settings presets, not a CLI tool.
How do I get it running?
Download the latest portable Windows x64 build, unzip it, and start the app directly — no separate installer is needed.
Do I need a specific GPU brand to use it?
No, it supports AMD, Nvidia, and Intel GPUs out of the box; the author tested it on an AMD RX 550, Nvidia RTX 3060/4060, and Intel UHD 620.
Is it free to use?
It's free for personal use only; commercial use requires buying a Premium version on Patreon.
Does it run on Mac or Linux too?
No, only Windows x64 builds are distributed; there's no mention of a macOS or Linux version.
What upscaling engines does it bundle?
It packages multiple engines including Waifu2x, Real-ESRGAN, Real-CUGAN, RTX Video Super Resolution, SRMD, RealSR, and Anime4K, so you can pick the one that best fits anime or real-life photos/videos.
Can it fix choppy video playback, not just upscale resolution?
Yes, it includes frame interpolation engines like RIFE, IFRNet, CAIN and DAIN that generate extra frames after upscaling to smooth out motion.
Does it only work on anime images despite the waifu2x name?
No, it also handles everyday real-life photos and videos alongside 2D anime content.
Does it take advantage of multiple GPUs or threads?
Yes, every built-in engine supports multi-GPU processing and the thread count is freely adjustable, with some settings auto-tuned based on your hardware.
