Extract text from UHarc compressed archives (UHA)
To convert UHA archives to another format, you need UHARC or other Compressed software.
To convert other file formats to the "Legacy Compressed Archive" file type, you need software like UHARC or a similar tool.
The .UHA file extension represents a UHarc Compressed Archive. Developed by Uwe Herklotz in the early 2000s, this high-compression archive format was utilized primarily in the gaming and software distribution communities to shrink large multimedia files into very small packages. Users typically interacted with these files using the original DOS-based UHARC command-line tool or third-party Windows GUI wrappers like WinUHA.
The main disadvantage of the .UHA format is that it is obsolete and strictly proprietary. Modern built-in OS extraction tools (like Windows Explorer or macOS Archive Utility) and standard archivers (like WinRAR or 7-Zip) do not natively support it. Furthermore, while the compression ratio is high, decompression is extremely slow and resource-intensive because it relies on legacy, single-threaded algorithms. Users must extract these archives and convert the contents into widely supported formats like ZIP or 7Z to ensure long-term accessibility.
Because .UHA relies on a closed, undocumented compression algorithm, standard online converters usually fail to process it. Only specific legacy software can properly read and decompress the binary data. However, just drag and drop your file to identify the format, view it, and convert it when possible on convert.guru. Our tool inspects the file headers, and if our analysis detects supported underlying text or embedded file streams, viewing or extracting may still be possible.
Convert.Guru analyzes your UHA file, detects the exact format, and lets you read the text inside.
Users also converted ZIP, RAR and FZ files.
If you want to convert UHA file to ZIP, RAR, 7Z, TAR, GZ, BZ2, XZ, LZMA, CAB, ACE, ARJ or LHA, you can use UHARC or similar software from the "High-compression file archiving" 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 UHA, try UHARC or another comparable tool in the "High-compression file archiving" 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 UHA converter.
