LZH to JAR Converter
Processing entirely on your device — large files may take a moment.
Repack a JAR as ZIP to inspect classes and resources with any unzip tool. If your files are still in LZH format, this page is the shortcut: LZH (LHA) is the archive format of the Japanese PC-98 era and Amiga scene — still attached to old downloads and doujin material.
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.
How LZH compares to JAR
| LZH | JAR | |
|---|---|---|
| Compression | LZ (LHA variants) | DEFLATE entries |
| Bundling | Multi-file | Classes + resources |
| Best for | Retro software archives | Java apps and libraries |

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 JAR format
A JAR is a ZIP with Java manners: class files, a MANIFEST.MF, resources and optional signatures. Any tool that opens ZIPs can open it — but converting to a plain ZIP strips the “is this executable?” ambiguity and makes browsing the contents painless.
Useful for auditing dependencies, extracting embedded resources, or checking what a library actually ships before adding it to a build.
+ Strengths
- ✓Standard Java delivery format
- ✓ZIP-based, tools abound
- ✓May carry signatures and manifests
! Limitations
- −Not a installer — just a package
- −Contents are class files, not source
Why convert LZH to JAR?
There is a concrete reason this conversion exists: No native OS support today JAR sidesteps that — Standard Java delivery format If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this LZH to JAR 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 JAR?
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.
Are the files inside my LZH archive modified?
No. Contents are unpacked in memory and repacked into JAR byte-for-byte — the conversion changes the container, never the files inside it.
What about folders and directory structure?
The full directory tree is preserved: folders stay folders, and deep paths arrive exactly as they were packed in the LZH file.
