LWO to TAR.GZ Converter
Processing entirely on your device — large files may take a moment.
LightWave Object and Gzipped TAR Archive 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. TAR.GZ is what open-source projects and Linux servers expect to receive.
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 TAR.GZ 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 LWO to TAR.GZ?
Converting makes sense where the strengths of TAR.GZ meet what LWO cannot give you. Universally understood on Unix-like systems 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 TAR.GZ 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 TAR.GZ model keep its colors and textures?
Only if TAR.GZ 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.
