LWO to TXZ Converter
Processing entirely on your device — large files may take a moment.
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 TXZ exactly like TAR.XZ.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

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 TXZ format
TAR.XZ pairs the tar container with XZ (LZMA2) compression — the highest-ratio member of the tar family and the de-facto release format of modern Linux distributions. The same source tree that lands 5% smaller than TAR.BZ2 and 20% smaller than TAR.GZ is why kernel.org and GNU mirrors standardised on it.
The trade is CPU time: XZ compresses slow (dictionary sizes up to 64 MB) but decompresses fast, which makes it ideal for one-time releases that get downloaded millions of times. When you need speed instead, TAR.GZ or TAR.ZSTD are the neighbouring picks.
+Strengths
- ✓Best compression ratio of the tar family
- ✓Standard release artifact of Linux distros
- ✓Fast decompression despite slow compression
!Limitations
- −Compression is CPU-heavy and single-threaded by default
- −Larger toolchain footprint than gzip on tiny systems
Why convert LWO to TXZ?
Converting makes sense where the strengths of TXZ meet what LWO cannot give you. Best compression ratio of the tar family Meanwhile Version spread (LWO2 vs LWOB) One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this LWO to TXZ 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.
Will my model look the same as a GLB?
Geometry, hierarchy and standard materials convert faithfully. Note that Draco-compressed GLB files and exotic extensions are not supported — export those as plain GLB from your original tool first.
Does the scale or orientation of the model change?
Vertex data is converted as-is. Formats without a unit system (like STL) are interpreted as millimeters by most 3D-printing tools — scale before converting if your model uses different units.
Will my TXZ model keep its colors and textures?
Only if TXZ can store them. Geometry converts faithfully; appearance data survives only when the target format has a place to put it. For full materials, GLB is usually the right target.
