LWO to GLB Converter
Processing entirely on your device — large files may take a moment.
LightWave Object and glTF Binary Model 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. GLB is what three.js, model-viewer, Unity and AR quick-look consume — the best choice for showing models on websites.
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 LWO compares to GLB
| LWO | GLB | |
|---|---|---|
| Structure | IFF FORM chunks (LWO2) | Scene graph + mesh + animation |
| Compatibility | LightWave, three.js, Blender (io) | Web/AR/game engines native |
| Best for | Broadcast VFX asset migration | Web, AR and full 3D scenes |

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 GLB format
GLB is the binary form of glTF 2.0 — the format the Khronos Group designed as “JPEG of 3D”. One self-contained file carries geometry, a full scene hierarchy, PBR materials with textures, skeletal animation and morph targets. It is the native asset format of three.js, Unity, Unreal, Blender and WebXR.
Converting to GLB is usually the upgrade path from OBJ/STL: materials become physically based and embedded, and scenes become portable in a single file. One honest caveat: Draco-compressed GLBs save space but many loaders need explicit decoder setup — plain GLB plays everywhere unconditionally.
+ Strengths
- ✓PBR materials, hierarchy and animation in one file
- ✓The web/AR standard — loads natively in three.js
- ✓Compact binary with texture embedding
! Limitations
- −Mesh-only: no CAD solids or NURBS
- −Older niche tools may not know glTF
Why convert LWO to GLB?
There is a concrete reason this conversion exists: Version spread (LWO2 vs LWOB) GLB sidesteps that — PBR materials, hierarchy and animation in one file If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this LWO to GLB 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.
How large can the LWO file be?
Everything runs on your device, so memory is the only ceiling. Dense meshes with millions of triangles convert fine on a desktop computer, just over a slightly longer coffee break.
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.
