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.
Where .lzh files surface today
The format faded from daily use around the millennium, but whole preservation scenes still speak it fluently:
| The trove | What is inside |
|---|---|
| Amiga software collections | Games and demos — .lha was the platform’s standard |
| Japanese BBS-era archives | Software and doujin works; names may be Shift-JIS |
| PC-98 preservation sites | A whole Japanese computing lineage packed in .lzh |
| Shareware CD-ROMs | Thousands of small archives pressed in the early 90s |
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.
