Common Use Cases
- Importing web 3D assets into Unity or Unreal Engine
- Bringing glTF models into Maya or 3ds Max
- Converting scanned models from web viewers to DCC tools
GLB is great for the web, but game engines and DCC tools prefer FBX. Unity, Unreal Engine, Maya, 3ds Max, and MotionBuilder all have deep FBX support with optimized importers. Converting GLB to FBX bridges the gap between web 3D and production pipelines.
GLB uses glTF PBR materials optimized for real-time web rendering, while FBX carries richer animation and material data that Autodesk tools and game engines understand natively.
Why Convert GLB to FBX?
Import into Unity and Unreal Engine
Both Unity and Unreal have mature FBX importers that handle materials, animations, and skeletal rigs reliably. FBX is the recommended import format for both engines.
Edit in Maya, 3ds Max, and MotionBuilder
Autodesk tools treat FBX as a first-class format. Converting your GLB to FBX gives you full editing access in the Autodesk ecosystem with all features intact.
Preserve animations and rigs
FBX has excellent support for skeletal animations, blend shapes, and complex rig hierarchies. Converting from GLB preserves this data for use in animation pipelines.
Standard exchange for production pipelines
Film, TV, and game studios use FBX as their primary interchange format. Converting web-sourced GLB models to FBX integrates them into professional workflows.

How to use
- Upload your GLB file. Drag and drop a .glb file onto the upload area, or click to browse. Files up to 500 MB are supported.
- Run the conversion. Click Convert File. Geometry, materials, and animations are extracted from the GLB and written as FBX.
- Download your FBX. Save the .fbx file and import it into Unity, Unreal, Maya, or any DCC tool. Files are deleted from our servers within 1 hour.
Frequently asked questions
- Are glTF PBR materials converted to FBX?
- Yes. Base color, metallic, roughness, normal, and emissive maps are mapped to FBX material properties. The visual result is close to the original, though some glTF-specific extensions may be simplified.
- Will Unity and Unreal import the FBX correctly?
- Yes. The output is a standard FBX file that both Unity and Unreal Engine import natively with their built-in FBX importers.
- Are skeletal animations preserved?
- Yes. Skeletal animations, blend shapes, and keyframe data from the GLB are preserved in the FBX output.
- Is converting GLB to FBX free?
- Yes. Free with no signup. Anonymous users get a daily allowance, registered accounts get higher limits, and Premium or Lifetime members get unlimited conversions.
- What is the file size limit?
- The maximum file size is 500 MB per conversion.
