LZH to XZ Converter
Processing entirely on your device — large files may take a moment.
LZH (LHA) is the archive format of the Japanese PC-98 era and Amiga scene — still attached to old downloads and doujin material. Unpack XZ into ZIP/TAR for tools that cannot read LZMA2.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

About the LZH format
LZH (also LHA) is the archive format that ruled Japanese PCs in the 8.3-filename era and the Amiga scene elsewhere. It compresses with a simple LZ scheme, predates ZIP's dominance, and still shows up attached to retro software, doujin archives and old BBS downloads.
No modern OS opens it natively, and LHA tools are niche. Converting LZH to ZIP is the one-step rescue: same files, universal container, no retro software hunt required.
+Strengths
- ✓The retro Japanese/Amiga archive standard
- ✓Simple, well-documented compression
!Limitations
- −No native OS support today
- −Weak compression by modern standards
About the XZ format
XZ wraps the LZMA2 algorithm: the best ratio of the common Unix compressors, which is why distribution packages and source releases pick it when bandwidth matters more than CPU.
Windows Explorer and many cross-platform tools cannot open it — unpacking to ZIP or TAR makes the payload portable.
+Strengths
- ✓Highest common ratio
- ✓Standard for Linux packages
- ✓Integrity checks built in
!Limitations
- −Memory-hungry at high settings
- −Sparse support outside Linux
Why convert LZH to XZ?
Think of it as moving your file to the container that fits the job. No native OS support today XZ works differently: Highest common ratio If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this LZH to XZ converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for LZH to XZ?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Is there a size limit for archive conversion?
There is no upload cap because nothing is uploaded — the practical limit is your device memory. A few hundred megabytes of unpacked content works comfortably on a modern computer.
Are the files inside my LZH archive modified?
No. Contents are unpacked in memory and repacked into XZ byte-for-byte — the conversion changes the container, never the files inside it.
