Why Choose Our Converter
Free & No Sign-Up
Convert GLB to FBX for free with no registration, no watermarks, and no hidden costs.
Game Engine Ready
FBX is the industry standard for game development. The output works in Unity, Unreal Engine, and Godot.
Animation Preservation
Skeletal animations and morph targets from the GLB file are transferred to the FBX output where possible.
Material Transfer
PBR materials from GLB are converted to FBX material format for use in desktop 3D software and game engines.
2 Ways to Convert GLB to FBX
Online GLB to FBX Converter (This Tool)
Best for: quick, no-install conversion
- Drag and drop your .glb file onto the converter.
- Wait for the automatic conversion.
- Download the FBX file and import into your game engine.
Pros: Free, no software install, works on any device.
Cons: Requires internet. Some complex GLB features may not fully transfer.
Blender (Free Desktop Software)
Best for: full control over export
- Open Blender and import your GLB (File > Import > glTF).
- Go to File > Export > FBX (.fbx).
- Configure export settings (animations, materials, scale).
- Click Export FBX.
Pros: Free. Full control over FBX export options. Best fidelity.
Cons: Requires installing Blender.
Quick Checks Before You Convert
Animation Data
GLB files may contain skeletal animations. FBX supports animations, but verify that bone hierarchies and skin weights transfer correctly after conversion.
PBR Materials
GLB uses glTF PBR materials. FBX uses a different material system. Some material properties like emissive and occlusion maps may not transfer perfectly.
Scale Settings
GLB uses meters by default. FBX can use different unit scales. Check the scale in your target software (Unity uses meters, Unreal uses centimeters).
Mesh Complexity
Large GLB files with many meshes may take longer to convert to FBX. Consider optimizing the mesh count before conversion.
Fixing Common Issues After Conversion
Materials appear wrong in game engine
GLB PBR materials and FBX materials use different workflows. After importing the FBX into Unity or Unreal, reassign textures and adjust material settings manually.
Animations not playing
Check that the FBX includes animation data. In Blender, ensure the animation is set as an Action before exporting. In Unity, verify the Animation component is configured.
Model scale is wrong
GLB uses meters. If your FBX appears too large or small, adjust the scale factor in the import settings of your game engine. Unity: set Mesh Factor to 0.01. Unreal: set Scale to 100.
Missing textures
GLB embeds textures. FBX may export textures separately. In Blender, use the Embed option in FBX export settings, or manually copy texture files alongside the FBX.
Frequently Asked Questions
How do I convert GLB to FBX?
Upload your .glb file using the converter above. The tool converts mesh geometry, materials, and animations to FBX format. Once complete, download the FBX file.
Is this GLB to FBX converter free?
Yes, completely free. No registration, no watermarks, no hidden costs.
Does converting GLB to FBX preserve animations?
Skeletal animations and morph targets from GLB are transferred to FBX where possible. However, some animation features may not perfectly convert due to differences in how glTF and FBX handle rigging.
What is the difference between GLB and FBX?
GLB is a web-optimized 3D format maintained by the Khronos Group. FBX is a proprietary format by Autodesk, widely used in game development and film. GLB is for web; FBX is for desktop game engines and animation pipelines.
How do I convert GLB to FBX in Blender?
In Blender, go to File > Import > glTF 2.0 (.glb/.gltf) to import your GLB. Then go to File > Export > FBX (.fbx). Configure export settings and click Export FBX.
Can I import GLB into Unity?
Unity does not natively support GLB. You need to convert GLB to FBX first, then import the FBX into Unity. Alternatively, use a GLB importer plugin for Unity.
Can I import GLB into Unreal Engine?
Unreal Engine has limited GLB support. Converting GLB to FBX first is the recommended approach for importing 3D models into Unreal.
Does FBX support PBR materials from GLB?
FBX supports materials but uses a different system than glTF PBR. Basic material properties transfer, but advanced PBR features like occlusion maps may need manual adjustment in your target software.
Can I convert GLB to FBX on Mac?
Yes. Our online converter works in any browser on macOS. Alternatively, use Blender on Mac to convert manually.
What is FBX format?
FBX (Filmbox) is a proprietary 3D file format developed by Kaydara and acquired by Autodesk. It is the industry standard for exchanging 3D assets including geometry, materials, animations, rigging, cameras, and lighting between Autodesk Maya, 3ds Max, Unity, and Unreal Engine.
