How to convert LZH to 7Z

  1. Add your .LZH file - drop it in the box above or click to browse.
  2. Convert it to .7Z in a few seconds.
  3. Download your new .7Z file.

What to expect

  • Conversion is fully lossless - every file byte extracted from the .lzh goes into the .7z unchanged.
  • LZH has no encryption support; if you need password protection, set an AES-256 password when creating the .7z.
  • .lzh and .lha are the same format - both extensions work with the same tools.

Frequently asked questions

Is the conversion lossless?
Yes - LZH and 7Z both use lossless compression, so every file inside is bit-for-bit identical after conversion.
Will the `.7z` be smaller than the original `.lzh`?
Usually yes; 7Z's LZMA2 algorithm is more efficient than LZH's -lh5- method, though gains are minimal for already-compressed content such as JPEG images or MP3 audio.
Can I open `.lzh` files on Windows without extra software?
No - Windows has no native LZH support; you need a tool such as 7-Zip or PeaZip.
Does Windows 10 open `.7z` files natively?
No - native .7z support was added in Windows 11 (build 23H2 and later); Windows 10 users need 7-Zip or a similar archiver.
