LZH to TGZ Converter
Processing entirely on your device — large files may take a moment.
Convert TGZ exactly like TAR.GZ — unpack, repack or inspect. 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 TGZ
| LZH | TGZ | |
|---|---|---|
| Compression | LZ (LHA variants) | gzip (DEFLATE) |
| Encryption | None | None |
| Bundling | Multi-file | TAR bundle, single stream |
| Best for | Retro software archives | Source releases and backups |

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 TGZ format
TAR.GZ is the classic Unix distribution shape: a TAR bundle squeezed through gzip (DEFLATE-based). Every Linux package of source code, every Apache tarball, every data-science dataset arrives this way. Decompression is a pipeline — untar the gzip stream — and the format is understood everywhere Unix ideas went.
gzip compresses the whole archive as one stream, which keeps ratio decent for text-heavy trees but means reaching file #400 requires decompressing the previous 399. Modern alternatives (zstd) are faster at similar ratios, yet tar.gz remains the safest common denominator.
+ Strengths
- ✓Universally understood on Unix-like systems
- ✓Good ratio for text and source trees
- ✓Preserves Unix permissions via TAR
! Limitations
- −Single stream — no random access
- −Slower than modern zstd
- −Two-step format (tar + gzip)
Why convert LZH to TGZ?
There is a concrete reason this conversion exists: No native OS support today TGZ sidesteps that — Universally understood on Unix-like systems If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this LZH to TGZ 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 TGZ?
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.
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.
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.
