# FBX to OBJ Converter

> To convert FBX to OBJ, open the FBX scene and write its meshes to an OBJ file with their geometry, UVs and normals. Kenerate's free converter does it in your browser: drop the .fbx, preview it and download the OBJ. Rigged models export in their rest pose; animation, bones and textures aren't carried over. Nothing is uploaded.

## Key facts
- Price: Free, no account
- Converts: FBX 7.x (binary or ASCII) → Wavefront OBJ
- Kept: Geometry, UVs, normals, mesh positions
- Not kept: Animation, bones, skinning, textures, cameras, lights
- Pose: Rest / bind pose
- Privacy: Converted locally — no upload
- No Autodesk tools: No Maya, 3ds Max or FBX SDK — just a browser tab.
- UVs survive: UV coordinates are written to the OBJ so the original textures can be re-applied.
- Preview first: Check the mesh and polycount before you download.
- Rest pose: Characters export in their bind pose — a clean starting point for sculpting or printing.
- Parse: The FBX node tree, meshes and materials are rebuilt.
- Pose: Rigged meshes are taken in their rest pose.
- Flatten: Node transforms are applied so parts keep their positions.
- Write: Vertices, UVs, normals and faces are written as OBJ.
- FBX (Filmbox): Proprietary scene format; by Autodesk, 1996 (Kaydara). Holds: Meshes and materials, Skeletons, skinning and animation, Cameras and lights. Lacks: An open specification. Best for: Game engines and animation pipelines. Opens in: Unity, Unreal Engine, Maya, 3ds Max, Blender.
- OBJ (Wavefront OBJ): Plain-text mesh; by Wavefront Technologies, 1980s. Holds: Vertices, faces, UVs and normals, Materials via a separate .mtl file. Lacks: Animation and rigs, Embedded textures. Best for: Moving static meshes between 3D apps. Opens in: Blender, Maya, 3ds Max, ZBrush, most slicers.
- Specification — FBX vs OBJ: Proprietary (Autodesk) | Open, plain text
- Geometry, UVs, normals — FBX vs OBJ: Yes | Yes
- Rigs and animation — FBX vs OBJ: Yes | No
- Embedded textures — FBX vs OBJ: Yes | No (separate files)
- Cameras and lights — FBX vs OBJ: Yes | No

## Steps
1. Open the FBX — Drop your .fbx onto the box above, or try the sample chest.
2. Preview — Check the mesh in Clay or Wire view.
3. Pick OBJ — Keep or turn off Z-up, and set a size if needed.
4. Download — Click Download OBJ.

## In depth

### Why convert away from FBX
FBX is owned by Autodesk and has no public specification, so tools read it with varying success [3]. OBJ is a simple open text format [2] that will open in essentially any 3D software for years to come.

### If you need more than a static mesh
For animation, rigs and materials in an open format, glTF/GLB is the better target [4]. OBJ is right for static meshes headed to sculpting, printing or CAD.

## FAQ
Q: Is FBX to OBJ conversion free?
A: Yes — free, no account, no install.

Q: Will my animation convert?
A: No. OBJ stores static meshes only, so the model is exported in its rest pose. Use GLB if you need animation in an open format.

Q: Are textures included?
A: No. The OBJ keeps UVs; re-apply the texture images in your 3D app.

Q: Which FBX versions work?
A: FBX 7.x, binary or ASCII. Very old 6.x files may not open.

Q: Is my file uploaded?
A: No — it's converted on your device.

Q: FBX or OBJ for Blender?
A: Blender imports both. Use FBX when the model has a rig, animation or embedded textures; use OBJ for a static mesh you'll sculpt, texture or print — it's plain text and opens the same in every app. Converting here keeps the UVs, so the textures can be re-applied.

Q: Can I convert FBX to GLB instead?
A: Yes — pick GLB in the same tool to keep materials and embedded textures.
