How to convert FBX to OBJ
FBX is Autodesk's proprietary 3D exchange format, used heavily in game engines like Unity and Unreal and 3D animation software. It can store mesh geometry, materials, skeletal rigs, animations, cameras, and lights in a single file. OBJ is an older, simpler text-based format that stores only geometry and basic material references. Converting FBX to OBJ is common when you need to move a mesh into software that supports OBJ but not FBX, or when you need the geometry in a plain, human-readable format.
This converter processes the FBX file directly in your browser using WebAssembly. Your 3D assets never leave your device, which matters for proprietary game art or client work covered by NDAs. Note that OBJ does not support animations, bones, or most material properties, so the output will be a static mesh with basic material references only.
Upload the FBX file
Drop your .fbx file onto the converter. Both binary FBX (the default Autodesk format) and ASCII FBX variants are accepted.
Review what will be preserved
OBJ stores vertex positions, UV coordinates, vertex normals, face indices, and material group references (.mtl). Animations, blend shapes, bone weights, and lighting data are not carried over.
Convert in browser
The WebAssembly engine parses the FBX scene graph, extracts the mesh data, and writes the OBJ file along with a companion .mtl file containing material definitions.
Download and import
Download the OBJ and MTL files. When importing into your target software, import both files together so material assignments are applied correctly.
Frequently asked questions
Will animations in the FBX file transfer to OBJ?
No. OBJ is a static geometry format and has no support for skeletal animation, morph targets, or keyframe data. If you need animation, consider converting to glTF or COLLADA instead.
What happens to textures?
The OBJ file references textures by file name in the .mtl file. The textures themselves are not embedded in OBJ (unlike FBX which can embed them). You need to keep your texture files alongside the OBJ and MTL when transferring to another system.
Is my 3D model uploaded to a server?
No. The entire conversion runs in your browser using WebAssembly. The file never leaves your device.
The OBJ looks different from the FBX in my 3D software. Why?
FBX and OBJ use different coordinate systems by default. FBX is typically Y-up, while OBJ can be interpreted differently by different importers. If your model appears rotated 90 degrees, apply a 90-degree rotation on the X axis in your target software.
My FBX has multiple objects. Will they all appear in the OBJ?
Yes. Multiple mesh objects in the FBX scene are written as separate object groups in the OBJ file, separated by the 'o' or 'g' keyword. Most 3D software will import them as separate objects.
