Extract text from compressed archives (LZH)
To convert LZH archives to another format, you need 7-Zip or other Compressed software.
To convert other file formats to the "LHA Compressed Archive" file type, you need software like 7-Zip or a similar tool.
The .LZH file is an LHA compressed archive created by Haruyasu Yoshizaki. It relies on Lempel-Ziv-Huffman compression to bundle and shrink multiple files into a single package. While historically dominant in Japan and early computing platforms like the Amiga, the format is mostly obsolete today. You can read more about its history on Wikipedia. Desktop archivers like 7-Zip or WinRAR are required to open these files.
The massive disadvantage of the .LZH format is its lack of native operating system support. Modern Windows, macOS, and Linux systems cannot open these files out-of-the-box, creating immediate workflow blocks for end users. Furthermore, .LZH lacks modern AES encryption. Because the format is obscure to modern systems, malicious actors frequently disguise harmful RAR or ZIP payloads by renaming them with an .LZH extension to bypass standard email security filters.
To ensure your archived files are actually accessible, you must convert them. For universal compatibility across all operating systems and web browsers, convert to ZIP. For high-ratio archiving, convert to 7Z.
Convert.Guru analyzes your LZH file, detects the exact format, and lets you read the text inside.
Users also converted EXE, PMA, LHZD, ZIP, DTD, PDF, BAK, RAR, BTW, JPG, VBS, BAT and IFO files.
If you want to convert LZH file to ZIP, RAR, 7Z, TAR, GZ, BZ2, XZ, LZMA, CAB, ACE, ARJ or LHA, you can use 7-Zip or similar software from the "Legacy Archive Compression" category. In the File menu, look for Save As… or Export….
To convert XXE, 7Z, Z, PAK, LHA, DEB, UUE, TAR, ZIP, PKG, RAR or ARJ files to LZH, try 7-Zip or another comparable tool in the "Legacy Archive 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 LZH converter.
