Convert FBX models to OBJ + MTL with an interactive 3D preview — parsing and export both run locally in your browser.
ASCII and binary FBX supported · large files (100MB+) are read in one pass, so parsing may take a moment
Need to convert an FBX file to OBJ format? This free online tool converts FBX 3D models to Wavefront OBJ + MTL directly in your browser — no software to install, no account required, and no file size restrictions imposed by a server. Since everything happens client-side using WebGL and three.js, your 3D models are never uploaded anywhere, making this the safest way to convert proprietary or client-confidential assets.
Whether you're preparing assets for a game engine, migrating between 3D pipelines, or need a universally compatible mesh format, this converter preserves the details that matter: UV coordinates, vertex normals, materials, and texture references. An interactive 3D preview lets you inspect the model before and after conversion, so you can verify geometry and materials look correct before downloading.
FBX (Filmbox) is a popular 3D file format developed by Autodesk for exchanging models, cameras, lights, animations, skeletons, and scene data between different 3D applications. It is widely used in Blender, Autodesk Maya, 3ds Max, MotionBuilder, Unity, Unreal Engine, Cinema 4D, and many CAD applications.
An FBX file can contain much more than geometry. Depending on how it was exported, it may include animation clips, rigging information, materials, textures, cameras, lights, and multiple meshes within a single file.
OBJ (Wavefront OBJ) is one of the oldest and most widely supported 3D model formats. Unlike FBX, OBJ focuses primarily on static geometry such as vertices, faces, texture coordinates (UVs), normals, and material references stored in an accompanying MTL file.
Because OBJ is an open and simple format, it is supported by almost every 3D application, rendering engine, CAD software, game engine, and 3D printing tool. This makes OBJ an excellent choice for exchanging static models between different software packages.
| Feature | FBX | OBJ |
|---|---|---|
| Geometry | ✔ | ✔ |
| Materials | ✔ | ✔ (MTL) |
| Textures | ✔ | ✔ |
| Animations | ✔ | ✘ |
| Skeleton / Rig | ✔ | ✘ |
| Cameras & Lights | ✔ | ✘ |
| Open Format | No | Yes |
| Best For | Game development & animation | Static models & interoperability |
The generated OBJ files can be imported into numerous professional and open-source 3D applications including:
| Issue | Cause | Solution |
|---|---|---|
| Missing textures | Texture files are unavailable | Keep textures in the same folder as the FBX. |
| Model appears black | Material references are missing | Export the MTL file together with textures. |
| Wrong orientation | Different coordinate systems | Rotate or change the export axis. |
| Broken shading | Incorrect normals | Recalculate normals before export. |
| Animations missing | OBJ doesn't support animation | Use FBX or glTF if animation is required. |
Every conversion takes place entirely inside your browser using JavaScript, WebGL, and three.js. Your models are never uploaded, stored, or processed on remote servers. This makes the converter suitable for confidential product designs, commercial game assets, engineering models, architectural projects, and proprietary client files.
FBX is a proprietary format developed by Autodesk and widely used in Maya, Blender, 3ds Max, and Unity. While powerful, it isn't always the best choice for interchange — some tools and pipelines only support the simpler, open OBJ format. Converting FBX to OBJ is useful for 3D printing preparation, importing into legacy renderers, sharing static meshes across software that lacks FBX support, or stripping away animation data when only geometry is needed.

Is this FBX to OBJ converter really free?
Yes, conversion is completely free with no limits on the number of files or file sizes beyond what your browser's memory can handle.
Are my files uploaded to a server?
No. Parsing and conversion both run locally in your browser using JavaScript and WebGL — your models never leave your device.
Does it support animations or rigs?
Bone and animation counts are detected and displayed, but since OBJ has no native support for skeletal animation, exported meshes are static bind-pose geometry only.
Can I convert multiple FBX files at once?
Yes — use the Batch Conversion tab to upload several files and export them all as one ZIP.
