Convert FBX to GLB
Convert a FBX file to GLB in your browser. Free, no upload, no sign-up.
Convert FBX files to GLB directly in your browser. The converter parses the FBX mesh, rebuilds it in memory and writes it out as GLB, keeping every triangle. Nothing is uploaded, there is no file size limit beyond your computer's memory, and the result downloads instantly. GLB is the format web browsers, AR viewers and e-commerce platforms expect; one self-contained file with materials included.
How to convert FBX to GLB
- 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 GLB
Adjust the export options if needed and click download. Meshes without materials get a neutral gray PBR material so the file renders correctly in viewers.
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 GLB file?
GLB is the binary container for glTF 2.0, the "JPEG of 3D" maintained by the Khronos Group. A single .glb file bundles geometry, PBR materials, textures and animations, and is the standard format for 3D on the web and in AR viewers.
Commonly used by: web viewers (three.js, model-viewer), AR on iOS and Android, Sketchfab, game engines
