How to convert FBX to GLTF
- Add your .FBX file - drop it in the box above or click to browse.
- Convert it to .GLTF in a few seconds.
- Download your new .GLTF file.
What to expect
- FBX materials using legacy Phong or Lambert shaders map only approximately to glTF PBR (metallic-roughness); reconnect textures to a Principled BSDF in Blender before re-exporting if materials look flat.
- Skeletal animation and morph targets carry over, but complex FBX constraints such as IK solvers or expression-driven curves may need baking in Blender before export.
- GLB packs mesh, materials and textures into one binary file; GLTF Separate keeps them split, which is useful when you want to edit textures independently.
Frequently asked questions
Can I get a single `.glb` file instead of separate `.gltf` and `.bin` files?
Yes - GLB is glTF in a single binary container. In Blender's export dialog set Format to glTF Binary; in FBX2glTF add the
--binary flag.Does animation transfer from FBX to glTF?
In most cases yes - keyframe and skeletal animation export correctly. Complex animation constraints may need baking in Blender (Object > Animation > Bake Action) before export.
Why are my textures missing after conversion?
FBX files sometimes reference textures by an absolute path that no longer exists on your machine; locate the image files and relink them in Blender before exporting.
The converted model has wrong scale or is rotated - how do I fix it?
FBX files vary in unit scale and up-axis; adjust the scale on import in Blender and set the correct up-axis in the glTF export panel.
