One of WudCompress’s strongest features is that it is . The original WUD image can be perfectly reconstructed from the WUX file. This is different from tools like WiiScrubber , which modify the data. Therefore, you can safely store your game collection as WUX files without any risk of data degradation, and decompress them whenever needed.
: While WudCompress was created by the lead developer of Cemu (Exzap), some community members now recommend JWUDTool for more advanced decompression or newer compression standards.
For Arch Linux users, the tool is also available in the Arch User Repository (AUR): wudcompress . Installing from the AUR is often the easiest route:
To ensure the compression works smoothly, organize your files: WudCompress.exe application in the same folder as your game files.
This creates a single compressed .wud file.
Once finished, a new .wux file will be created in the same folder.
A year later, wudcompress had no corporate backing, no flashy website—just a dedicated repo, an archive of release notes, and an occasionally updated README. People packaged it for their systems, wrapped it into tiny containers for backups, and used it wherever space felt scarce. Jaya kept a copy in a drawer of her mind: a simple command, a careful build, the satisfying clack of the keyboard when a backup finished smaller than it began.
In this guide, we will walk you through exactly what wudcompress is, why you need it, and how to install it step-by-step.
