Extract text from Unreal Engine packages (UZ)
To convert UZ packages to another format, you need Unreal Engine or other Game software.
To convert other file formats to the "Compressed Game Package" file type, you need software like Unreal Engine or a similar tool.
A .UZ file is a compressed package archive created by earlier versions of Epic Games Unreal Engine. Game developers and server administrators use this format to compress maps, textures, sounds, and mods. Shrinking these files saves significant bandwidth when players download custom content directly from a multiplayer server.
To decompress and use a .UZ file, players typically rely on the native ucc.exe utility bundled with legacy games like Unreal Tournament. The primary disadvantage of the .UZ format is its heavily proprietary nature. Because it uses a specialized Unreal compression algorithm, standard extraction tools like 7-Zip or WinRAR will throw errors and fail to open it.
Converting a .UZ file means decompressing it back into its original Unreal Engine asset formats. Target formats include UNR (Maps), UTX (Textures), UAX (Audio), or U (System Code). Without extraction, the game engine cannot load the map or mod.
This file format is exceptionally difficult to open or convert online. It is a closed, proprietary format designed exclusively for old game engines, which is why standard online converters fail to process it. Only the original software can properly read or export the data. However, just drag and drop your file on convert.guru to identify the format, inspect the file's hex headers, and show internal content. If our analysis detects a supported underlying or embedded format, viewing or extraction may still be possible.
Convert.Guru analyzes your UZ file, detects the exact format, and lets you read the text inside.
Users also converted U, UAX and T3D files.
If you want to convert UZ file to ZIP, RAR, 7Z, TAR, GZ, BZ2, XZ, LZMA, CAB, ACE, ARJ or LHA, you can use Unreal Engine or similar software from the "Game Asset Compression" category. In the File menu, look for Save As… or Export….
To convert XXE, 7Z, Z, PAK, LHA, DEB, UUE, TAR, LZH, ZIP, PKG or RAR files to UZ, try Unreal Engine or another comparable tool in the "Game Asset Compression" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our UZ converter.
