FBX → OBJ · local conversion
Move model geometry from an FBX asset into a widely supported text OBJ file without uploading it.
FBX → OBJ
This converter exports geometry only. FBX materials, textures, animation, rigs, cameras and lights are not included in the OBJ download, and no companion MTL file is generated.
FBX can describe animation, skeletons, cameras, lights, materials and complex scene relationships. OBJ is a simpler text format centered on vertex positions, texture coordinates, normals and faces.
Drop a binary or ASCII .fbx file, select Convert to OBJ and save the result. Import the OBJ into your target 3D application and check axis orientation and units before continuing the workflow.
Drag a .fbx file into the converter above, or click to browse. The file stays on your machine — the browser reads it directly and nothing is uploaded to a server. Files up to 50 MB are supported.
Conversion runs inside a Web Worker so the page stays responsive. The converter reads a scene graph with meshes, rigs, cameras and animation, then flattens every visible mesh into OBJ output. Larger models take longer to parse; meshes with several hundred thousand triangles usually finish in a few seconds.
When conversion finishes, the download starts locally. The output keeps the original filename with a .obj extension. There is no account step, no queue and no watermark.
Open the result in Blender, MeshLab, ZBrush, Cinema 4D and most CAD viewers. Confirm dimensions and orientation before applying print or render settings. Because FBX carries unit metadata and OBJ does not, the scale check matters here.
| FBX | OBJ | |
|---|---|---|
| Full name | Filmbox | Wavefront OBJ |
| File structure | proprietary Autodesk binary or ASCII file | plain-text file listing vertices and faces |
| Geometry model | a scene graph with meshes, rigs, cameras and animation | grouped meshes with optional vertex normals and UVs |
| Stores color & materials | Yes | No |
| Carries unit metadata | Yes | No |
| Typically comes from | Maya, 3ds Max, Blender, Cinema 4D and Mixamo | a widely readable text interchange format |
The usual situation: you have a .fbx file from an animation or game-asset pipeline, but the tool you need to use next only reads OBJ. Maya, 3ds Max, Blender, Cinema 4D and Mixamo all export FBX, while Blender, MeshLab, ZBrush, Cinema 4D and most CAD viewers typically expect .obj. OBJ is plain text and readable by almost any 3D application, which makes it a dependable interchange and archival format.
FBX stores a scene graph with meshes, rigs, cameras and animation; OBJ stores grouped meshes with optional vertex normals and UVs. Color, materials and textures do not survive the conversion — that is a property of the OBJ format itself, not a limitation of this converter. FBX records units explicitly and OBJ does not, so you confirm dimensions after import. The geometry itself — triangle faces and vertex positions — is preserved in full, and that is what printing and downstream modeling actually depend on.
The model is tens or hundreds of times too large or small. Units did not line up; rescale in millimeters inside your target application. The output is empty or partial. The source may keep geometry on hidden nodes — unhide them and re-export from the original tool. Surfaces render black or inside-out. The converter recomputes normals for meshes that lack them, but faces that were already inverted in the source need fixing in Blender, MeshLab, ZBrush, Cinema 4D and most CAD viewers. The file will not open. Check that the extension matches the real format; a fresh export from the source application usually resolves it.
Most online converters upload your file to a server, convert it there and send the result back. For unreleased product designs, client models or anything under NDA, that upload is the moment the file leaves your control. This converter runs three.js loaders and exporters locally in your browser, so the file never crosses the network — the page will even convert with your connection turned off.
