How to convert LZH to ZIP

Conversion is always two steps - extract from LZH, then recompress to ZIP - no single tool does this in one click.
LZH and ZIP use comparable compression algorithms, so the resulting .zip will be a similar size to the original .lzh.
File names in old Japanese LZH archives may use Shift-JIS encoding and can appear garbled; 7-Zip and PeaZip handle this better than most tools.

Is .lzh the same as .lha?

Yes - .lzh and .lha are two extensions for the same LHA format. 7-Zip and PeaZip handle both identically.

Will the ZIP file be larger than the LZH?

Usually similar in size. LZH (-lh5-) and ZIP (Deflate) offer comparable compression, so the difference is typically negligible.

Can macOS open LZH files without extra software?

No - macOS does not support LZH natively. Install The Unarchiver (free, App Store) to extract, then use Finder to compress the output to ZIP.

Do I need the original LHA program to open old archives?

No - modern tools like 7-Zip, PeaZip, and lhasa read LZH/LHA archives without the original DOS-era LHA executable.
