LZH to BZ2 Converter
Processing entirely on your device — large files may take a moment.
LHA/LZH Archive and BZip2 Compressed File exist for different jobs: LZH (LHA) is the archive format of the Japanese PC-98 era and Amiga scene — still attached to old downloads and doujin material. Convert BZ2 to ZIP or TAR when modern tools need a friendlier container.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.
How LZH compares to BZ2
| LZH | BZ2 | |

| Compression | LZ (LHA variants) | BWT + Huffman |
| Bundling | Multi-file | Single file |
| Best for | Retro software archives | Large text dumps |

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 BZ2 format
BZ2 applies the Burrows–Wheeler transform: slower than gzip but noticeably smaller, which is why Wikipedia database dumps and old source tarballs still arrive as .bz2.
Few GUI tools ship a bz2 reader these days, so converting the contents into a ZIP or TAR is the practical way to hand the payload to someone else.
+Strengths
- ✓Better ratio than gzip
- ✓Common in dumps and archives
- ✓Mature, stable format
!Limitations
- −Slow to compress and decompress
- −Declining tool support
Why convert LZH to BZ2?
Think of it as moving your file to the container that fits the job. No native OS support today BZ2 works differently: Better ratio than gzip 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 BZ2 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 BZ2?
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.
Are the files inside my LZH archive modified?
No. Contents are unpacked in memory and repacked into BZ2 byte-for-byte — the conversion changes the container, never the files inside it.
