Convert GLB to FBX

Verified by Adam B.· reviewed by FE Editorial ·updated Jul 3, 2026
QUICK ANSWER
Is it possible to convert GLB to FBX?
Yes - GLB converts to FBX.

The fastest route is our free converter above - upload your .glb and get a .fbx back in seconds. For files with animation or skeletal rigs, Blender gives the most reliable result, though PBR materials will need reassigning in the target application.

Why convert GLB to FBX?

FBX is the standard interchange format for Maya, 3ds Max and game-engine pipelines such as Unreal Engine. Many studios require .fbx over .glb because it carries meshes, UVs, bones and keyframe animation in a single file that most DCC tools open without extra plugins. See the .FBX format page for background on the format's history and structure.

How to convert GLB to FBX

Blender - import GLB, export FBX FREE

Open your .glb via File > Import > glTF 2.0, then use File > Export > FBX; Blender is fully free and open-source and handles meshes, rigs and keyframe animation.

Command line - Blender headless CLI

Automate the conversion with a Python script using blender --background --python export_fbx.py.

Decompress Draco GLBs first - glTF-Transform CLI

If your .glb uses Draco compression, run gltf-transform decompress input.glb output.glb before importing into Blender or the converter above.

Quality & what to watch

  • PBR metallic-roughness materials from .glb have no direct equivalent in FBX - expect to reassign or reconnect textures in Maya, Unreal Engine or your target app after conversion.
  • Draco-compressed .glb files cannot be read by most converters until decompressed; use glTF-Transform to remove the compression first.
  • The resulting .fbx will be noticeably larger than the source .glb because FBX does not use GLB's compact binary packing.

Frequently asked questions

Does animation survive the conversion from GLB to FBX?
Keyframe and skeletal animation transfers in most cases. In Blender's export panel, choose FBX version 7.4 (2014/2015) for the broadest compatibility with game engines.
Why does my converted FBX look wrong in Maya or Unreal Engine?
The most common cause is materials: GLB uses PBR metallic-roughness data that does not map one-to-one to FBX materials, so textures need to be reconnected manually in the receiving application.
Can I convert multiple GLB files to FBX at once?
Yes - Blender's headless mode (blender --background --python script.py) lets you loop through files and automate the import/export pipeline in bulk.
Is FBX an open format?
No - FBX is proprietary to Autodesk with no public specification; Blender reverse-engineers it and works well in practice, but occasional edge cases occur with complex scenes.
