Extract text from Unix compressed files (Z)
To convert Z compressed files to another format, you need Unix compress or other Compressed software.
To convert other file formats to the "Legacy Compressed Archive" file type, you need software like Unix compress or a similar tool.
The .Z file is an outdated compressed archive format created by the legacy Unix compress utility using the Lempel-Ziv-Welch (LZW) algorithm. It was traditionally used on early Unix systems to reduce file size. Sometimes, a .Z extension may also denote zlib streams, disguised RAR archives, or game assets for titles running on Unreal Engine.
You can natively extract .Z files on Linux and macOS using terminal commands like uncompress or gzip -d. On Windows, you will need third-party archivers like 7-Zip or WinRAR.
The .Z format is functionally obsolete and comes with severe limitations. It offers poor compression ratios compared to modern alternatives, lacks password protection, and does not support solid archiving. Crucially, the compress command only compresses a single file at a time; to compress entire folders, it had to be combined with a TAR file, resulting in a clunky .tar.Z archive. Because typical Windows users cannot open .Z files natively, sharing them often causes workflow bottlenecks.
To ensure your files are universally accessible, you should extract and convert them. For general sharing across all platforms, convert to ZIP. For Linux server environments, convert to .TAR.GZ. For the smallest possible file size, switch to 7Z.
Convert.Guru analyzes your Z file, detects the exact format, and lets you read the text inside.
Users also converted LIS, PVR, Z01, 7Z, ZIP, Z02, ZLIB, PDF, TAR, INP, EPUB, BAK and JPG files.
If you want to convert Z file to EST, UTC, IST, ZIP, RAR, 7Z, TAR, GZ, BZ2, XZ, LZMA or CAB, you can use Unix compress or similar software from the "Data Compression and Archiving" category. In the File menu, look for Save As… or Export….
To convert XXE, 7Z, PAK, LHA, DEB, UUE, TAR, LZH, ZIP, PKG, RAR or ARJ files to Z, try Unix compress or another comparable tool in the "Data Compression and 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 Z converter.
