What does this tool do?

LHA (often seen as .lzh) is an old but still encountered compression/distribution format found in archives. The LHA/LZH ecosystem, developed by Haruyasu Yoshizaki in 1988, is particularly encountered today in old software archives and legacy packages.

What actually happens during conversion?

This tool does not “change” the content of the files; it changes the packaging and compression container:

  • The LHA/LZH archive is opened (the files inside are extracted).  
  • It is re-archived according to the selected target format (ZIP/7Z/RAR or TAR + gzip/bzip2).  Result: The content remains the same; the changing factor is the archive standard, compatibility, and compression characteristics.

Format selection: which one in which situation?

  • ZIP: The most common “opens everywhere” option; the ZIP specification is explicitly documented by PKWARE.  
  • 7Z: Preferred in scenarios focused on high compression; common methods in 7z format are LZMA/LZMA2.  
  • TAR: Collects files in a single stream (packaging); if you don’t want compression, “clean tar” makes sense.  
  • TAR.GZ: TAR package + GZIP compression; the GZIP format is lossless and includes CRC for error detection.  
  • TAR.BZ2: TAR package + bzip2 compression; bzip2 is a single file compressor (hence TAR is needed first).  
  • RAR: Often requested due to “delivery standard/institutional request”; the goal is to ensure RAR compatibility.

Critical risks specific to LHA/LZH (must be in your tool texts)

  • File name encoding: Old LHA archives may display file names as “garbled characters” with different code pages (especially Japanese sources). An option in the tool like “fix file names / normalize to UTF-8” would be very valuable.
  • Encrypted archive: If there is a password, conversion is only possible with the correct password; the tool should give a clear warning.
  • Corrupted archive: In LHA files with CRC/read errors, “recovery may be attempted” but no guarantee can be given; do not keep the user waiting with false hope.

Professional features that should be in this tool

  • Batch conversion + download all outputs at once
  • Preserve folder structure and file timestamps
  • File name normalization (option to fix garbled characters)
  • Output options: compression level (for 7z/tar.*), “store/deflate” (for zip)
  • Conversion report: number of files, total size, compression ratio
  • Security text: automatic deletion of uploaded files, temporary storage duration
