Convert FBX to glTF
Convert a FBX file to glTF in your browser. Free, no upload, no sign-up.
Convert FBX files to glTF directly in your browser. The converter parses the FBX mesh, rebuilds it in memory and writes it out as glTF, keeping every triangle. Nothing is uploaded, there is no file size limit beyond your computer's memory, and the result downloads instantly. glTF gives you a readable JSON scene that is easy to inspect, diff or post-process in a build pipeline.
How to convert FBX to glTF
- 1Drop your FBX file
Drag a .fbx file onto the box above or click to choose one. Binary and ASCII FBX (version 7.0+) are read. Animation, rigs and external textures are ignored; only the mesh geometry is converted.
- 2Check the preview
The model renders in 3D so you can confirm it loaded correctly. Dimensions, volume and triangle count are shown next to it; open edges are flagged if the mesh is not watertight.
- 3Download the glTF
Adjust the export options if needed and click download. Buffers are embedded in the JSON as base64, so the output is a single file.
What is a FBX file?
FBX is Autodesk's proprietary interchange format for animation and game assets. It carries meshes, rigs, animation, cameras and materials. Because it is closed and complex, FBX files are rarely accepted by 3D printing tools directly.
Commonly used by: Maya, 3ds Max, Unity, Unreal Engine, Mixamo

What is a glTF file?
glTF is the JSON form of the same Khronos standard as GLB. The .gltf file describes the scene as readable JSON; binary buffers and textures may be embedded as base64 or kept as separate files. It is convenient when you want to inspect or edit the scene description by hand.
Commonly used by: web developers, Babylon.js / three.js, Blender, Unity and Unreal importers
