Tenpi Waifu2x GUI Save

Waifu2x GUI

This is a GUI app that can upscale anime-styled images, gifs, and videos using waifu2x, Real-ESRGAN, or Real-CUGAN. It aims to be simple to use, but you can access more advanced settings in the top bar.

Note: Upscaling videos and gifs will take a very long time without a high-end graphics card!

Features:

• Upscale and/or denoise images (png, jpg, webp, etc.)
• Upscale and/or denoise animated images (gif, animated webp)
• Upscale and/or denoise videos (mp4, webm, ogv, etc.)
• Upscale and/or denoise PDFs (pdf)
• Apply effects such as speed or reverse (animated images/videos)
• Customize settings (noise, scale, mode, framerate, etc.)
• Upscale multiple images (or multiple frames of an animated image/video) concurrently
• Change the upscaler (waifu2x, Real-ESRGAN, Real-CUGAN, or custom)

Warning: Upscaling too many images in parallel can cause your computer to freeze if it runs out of CPU/memory.

Waifu2x

Waifu2x only supports scale factors in multiples of 2 from 1/2/4 and noise level -1/0/1/2/3 (set to -1 for no denoise).

Real-ESRGAN

Real-ESRGAN only supports scale factors between 2-4, and all other options are ignored. By setting the scale factor to 4x, it will use the slower Anime4x model that gives better results, so it is recommended to upscale images at 4x when using Real-ESRGAN.

Real-CUGAN

Real-CUGAN only supports scale factors 1/2/3/4, and noise level -1/0/1/2/3 and only noise 0 and 3 for scale factors 3/4. This is probably the best performing upscaler out of the defaults.

Custom Models

You can add custom pytorch models to the "models" folder in the location the app is installed, same place ffmpeg folder is located. If the folder doesn't exist, create it. You need to install python in order to run them. If you still have trouble, try installing the dependencies:

pip3 install torch torchvision opencv-python Pillow numpy spandrel --compile --force-reinstall

Installation

To install, download the latest installer from the releases tab. Updates can be installed automatically.

Note: If you install it under C:/Program Files you might need to run it as administrator.

MacOS

On MacOS unsigned applications won't open, run this to remove the quarantine flag.

xattr -d com.apple.quarantine /Applications/Waifu2x\ GUI.app
