Enhance Your Images with Effortless Cross-Platform Super-Resolution at Any Scale

MacOS x64 MacOS arm64 Windows x64 Windows arm64 Linux x64 codecov CI-Test CI-Build Release Download GitHub

This is a powerful tool that allows for image super-resolution to arbitrary sizes using multiple models, designed to enhance the resolution and quality of images, making them clearer and more detailed. Presently, it supports several models, such as RealCUGAN, RealESRGAN, and Waifu2x.



use Final2x to perform 4x super-resolution on a 256x256 Hutao RGBA image



Download the latest release from here.


Just Run! Furthermore, you can use package mananger to install and upgrade.


winget install Final2x


sudo spctl --master-disable
# Disable Gatekeeper, then allow applications downloaded from anywhere in System Preferences > Security & Privacy > General
xattr -cr /Applications/

In first time, you need to run the command above in terminal to allow the app to run, and first process may very slow because of Apple's Check.


For General Linux (Suggested, download linux-pip)

Python >= 3.8, then check install in terminal.

pip install Final2x-core
Final2x-core -c # cache models
apt install -y libomp5 xdg-utils

For Deb/Ubuntu
