Wudcompress is an open-source command-line utility designed for the Nintendo Wii U emulation and homebrew community. Raw Wii U disc dumps (WUD files) are consistently 23.3 GB in size, regardless of how much actual data the game uses. Wudcompress strips out the dummy padding data and compresses the file into a WUX format.
