What is it?

Final2x is a desktop application that enlarges images and restores detail using super-resolution models. It runs on Windows, macOS, and Linux, and ships with built-in models while also allowing users to load their own custom models.

The app is built with Electron, Vue 3, and TypeScript, with a Python command-line backend (Final2x-core) that is built on the cccv image restoration library and uses PyTorch. On Linux, the backend is installed separately via pip alongside Python and PyTorch, and system libraries such as libomp are required.

The project is aimed at people who need to upscale photos or artwork without working directly with machine learning code. Developers can also use the core package from the command line.
