Extract LHA/LZH archives.
Open LHA and LZH archives — retro formats, done locally.
Drop LHA/LZH archives here
or browse your files
Paste with ⌘V · or drop files anywhere on the page
Files never leave your device. Everything runs in your browser, nothing touches a server — tools you've used even work offline.
LHA (.lzh) ruled Japanese software distribution and the Amiga scene long before ZIP won globally — and retro archives, abandonware collections and old game mods still carry it. Drop one here and its files extract in your browser, no vintage tooling required.
How it works
- Drop files anywhere on the page, click to browse, or paste with ⌘V.
- Pick a quality or preset — or set an exact target size and let the tool find it.
- Compress, compare before/after, and download — individually or as a ZIP.
Rescuing old archives
Retro collections mix formats freely — LHA next to ARJ next to early ZIP. Everything opens on the same archive tab, and once extracted, repacking into a modern 7Z keeps the bytes and drops the archaeology.
Frequently asked questions
LHA or LZH — which is it?
The same format: LHA is the archiver, .lzh its usual extension (with .lha common on Amiga). Both extensions open identically here.
Do Japanese file names decode correctly?
Usually — but archives from 90s Japanese systems often store names in Shift-JIS, which no modern tool can always guess right. File CONTENT extracts perfectly either way; a garbled name is cosmetic and can be fixed after download.
What made LHA special back then?
It was free with source code when PKZIP was shareware — so Japanese vendors, id Software (DOOM shipped in LHA!) and the Amiga community standardized on it. A nice reminder that formats win on licensing as much as on ratio.
Is it private?
Yes. The archive is opened and unpacked on your own device — its contents are never uploaded, and a password, if one is needed, is used locally and never transmitted. The server does nothing but deliver this page. Want proof? Run one file through, switch your connection off, and run another — it still works.
