FBX to OBJ Converter with Local 3D Preview and MTL
Open an Autodesk FBX model directly in your browser, inspect its real mesh, and export Wavefront OBJ geometry with UVs, normals and an optional MTL package. Nothing is uploaded.
FBX parsing, 3D preview and OBJ export happen locally. Your model is never uploaded.
No FBX model loaded
Load a mesh to inspect geometry before creating Wavefront OBJ output.
How to convert FBX to OBJ
Choose an FBX model, inspect the parsed mesh, decide whether to package materials, then export OBJ locally.
Choose an FBX model
Select or drop one ASCII or binary .fbx file up to 100 MB and 2 million vertices.
Inspect the real mesh
Rotate and zoom the locally parsed scene, then review mesh, triangle, vertex, material and animation counts.
Download OBJ output
Export one .obj file or a ZIP containing OBJ, MTL and readable embedded diffuse textures.
FBX to Wavefront OBJ output
OBJ is a static mesh format, so geometry transfers well while FBX rigging and animation do not have an OBJ equivalent.
| Control | Setting | Effect |
|---|---|---|
| Geometry | Meshes, vertices and faces | Applies FBX object transforms and exports static OBJ coordinates |
| Surface data | UVs and normals | Preserves texture coordinates and shading normals when present |
| Materials | Optional MTL package | Exports basic colors and any readable embedded diffuse texture images |
| Animation | Reported, not exported | OBJ has no skeleton, skinning, bone or animation format |
| Processing | Local browser | FBX parsing, WebGL preview and OBJ generation require no upload |
FBX vs OBJ: what is preserved
The converter exposes format differences before download so production assets can be checked in the target application.
| Characteristic | Source | Output |
|---|---|---|
| Geometry | Hierarchical transformed meshes | Static transformed mesh objects |
| Materials | Rich DCC and PBR properties | Basic MTL colors and texture references |
| Textures | Embedded or external | Readable embedded images can be packaged; external files require relinking |
| Animation | Skeletons, skinning and clips | Not supported by Wavefront OBJ |
| Compatibility | Strong DCC and game-engine support | Very broad 3D editor, CAD viewer and printing support |
Private Three.js FBX parsing and OBJ export
The same local scene used for the interactive preview is exported, providing direct evidence that the FBX mesh was parsed.
Real FBX scene parsing
Binary and ASCII FBX data are decoded into meshes rather than renamed or passed through a server endpoint.
Interactive mesh verification
A stable WebGL viewport lets you rotate the loaded model and catch missing or malformed geometry before export.
Useful OBJ package
The ZIP option adds an MTL sidecar and any diffuse texture image that the browser can read from the FBX material.
Production-safe limitations
External texture paths, proprietary shaders, bones and animations cannot be represented fully and are called out explicitly.

Use GLB when animation or self-contained textures matter, or another direction for different source models.
FBX to OBJ converter FAQ
How do I convert FBX to OBJ?
Choose an .fbx file above, inspect the loaded model, select OBJ-only or the OBJ/MTL ZIP package, then choose Convert FBX to OBJ and download the result.
Does FBX to OBJ preserve textures and materials?
Basic material colors and readable embedded diffuse textures can be included in the MTL ZIP. External texture files referenced by path are not inside the uploaded FBX and must be relinked manually.
Can OBJ preserve FBX animations and bones?
No. Wavefront OBJ is a static mesh format and has no standard skeleton, skinning or animation data. Use FBX to GLB when animation must remain.
Does the converter preserve UVs and normals?
Yes when those attributes are present in the parsed FBX mesh. Object transforms are applied to exported positions and normals.
Why can the OBJ look different after conversion?
FBX may contain proprietary shaders, layered materials, unit conventions and external textures that OBJ cannot express. Check scale and relink external maps in the target application.
Is the FBX model uploaded?
No. FBX parsing, statistics, 3D preview, OBJ/MTL creation and ZIP packaging all happen locally in this browser.
Convert FBX mesh to OBJ locally
Inspect the geometry, export a useful OBJ package, and keep the model private.
