LWO to BZ2 Converter
Processing entirely on your device — large files may take a moment.
LightWave Object and BZip2 Compressed File exist for different jobs: LWO is LightWave 3D's object format — an IFF-style container with layers, surfaces and VMAPs that broadcast and film VFX shops have used since the 1990s. 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.

About the LWO format
LWO is LightWave's object format — an IFF-style container of layers, point/ polygon lists, surface definitions and VMAP weight/UV maps. NewTek's LightWave rendered Babylon 5 and dozens of TV shows, and broadcast VFX houses still hold decades of LWO assets.
three.js includes an LWOLoader, so objects convert to glTF/OBJ in the browser — layers merge into a scene graph with surfaces translated to PBR-ish materials.
+Strengths
- ✓Layered, surface-rich container
- ✓Broadcast/VFX heritage
- ✓Native three.js loader
!Limitations
- −Version spread (LWO2 vs LWOB)
- −Envelope/animation data not portable
- −Niche outside LightWave studios
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

Frequently asked questions
Is this LWO 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 LWO 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 LWO file.
Are the files inside my LWO 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.
