LWO to OBJ Converter
Processing entirely on your device — large files may take a moment.
LightWave Object and Wavefront OBJ 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. OBJ opens in Blender, Maya, 3ds Max, SketchUp and countless model viewers — the safest interchange format for meshes.
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 OBJ
| LWO | OBJ | |
|---|---|---|
| Structure | IFF FORM chunks (LWO2) | Mesh + UVs (+ groups) |
| Compatibility | LightWave, three.js, Blender (io) | Universal exchange veteran |
| Best for | Broadcast VFX asset migration | Static model exchange |

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 OBJ format
OBJ (Wavefront, 1990s) is the veteran of 3D model exchange: a text file of vertices, UV coordinates and faces, optionally paired with an MTL material file and texture images. It predates every modern pipeline yet still opens everywhere, which keeps it as the default export of modeling tutorials, asset stores and scan software.
It is static by design — no animation, no rigging, no scene hierarchy beyond groups — and MTL's habit of referencing textures by relative path means a lonely .obj file often shows up untextured. For static meshes with appearance, it remains a dependable common ground.
+ Strengths
- ✓Opens in every 3D application, old and new
- ✓Text-readable and easy to generate programmatically
- ✓Carries UVs and materials via MTL
! Limitations
- −No animation, rigging or hierarchy
- −Texture references break when files travel alone
- −Text format is bulky for dense meshes
Why convert LWO to OBJ?
There is a concrete reason this conversion exists: Version spread (LWO2 vs LWOB) OBJ sidesteps that — Opens in every 3D application, old and new If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this LWO to OBJ 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.
What happens to colors and materials?
The OBJ format only stores geometry, so colors, textures and materials from the source file are dropped — the shape converts perfectly, appearance does not. If you need materials, convert to GLB instead.
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 OBJ model keep its colors and textures?
Only if OBJ 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.
