About GL Transmission Format Binary
Common Use Cases
- Publishing Autodesk FBX models on the web
- Loading 3D assets in Three.js and Babylon.js
- Embedding models in AR experiences and Google viewers
FBX is the dominant format for game engines and Autodesk tools, but the web runs on glTF. GLB packs geometry, materials, textures, and animations into a single binary file that loads fast in browsers and AR viewers. Converting FBX to GLB is the standard pipeline for getting game-ready assets onto websites, product configurators, and mixed-reality experiences.
FBX is a proprietary Autodesk format optimized for Maya, 3ds Max, and game engines, while GLB is the open web standard for 3D that works natively in browsers without plugins.
Why Convert FBX to GLB?
Display 3D models in any browser
GLB is the format behind WebGL and WebGPU 3D experiences. Three.js, Babylon.js, A-Frame, and Google Model Viewer all load GLB natively, so converting your FBX is all it takes to get a model on the web.
Single file with embedded textures
GLB packs geometry, materials, and textures into one binary file. No more managing separate texture folders or broken file references when sharing assets.
Smaller file size for faster loading
GLB uses binary encoding and can reference Draco or meshopt compression. The resulting files are typically much smaller than equivalent FBX, which means faster page loads and lower bandwidth costs.
AR and mixed-reality ready
Apple AR Quick Look, Google Scene Viewer, and Meta Quest all support GLB/glTF natively. Converting from FBX makes your models viewable in augmented reality on phones and headsets.
When to use each
Use FBX when...
- Working in Maya, 3ds Max, or MotionBuilder
- Importing into Unity or Unreal Engine
- Exchanging animated rigs between DCC tools
- You need Autodesk-specific material features
- The pipeline is entirely Autodesk-based
Use GLB when...
- Publishing 3D content on the web
- Loading models in Three.js or Babylon.js
- Embedding 3D in AR viewers on phones
- You want a single self-contained binary file
- Optimizing 3D assets for fast browser loading
Common use cases
- Publishing Autodesk FBX models on the web
- Loading 3D assets in Three.js and Babylon.js
- Embedding models in AR experiences and Google viewers
How to use
- Upload your FBX file. Drag and drop a .fbx file onto the upload area, or click to browse. Both binary and ASCII FBX are supported, up to 500 MB.
- Run the conversion. Click Convert File. Geometry, materials, and animations are translated to glTF PBR format and packed into a single GLB binary.
- Download your GLB. Save the .glb file and load it in Three.js, Babylon.js, Google Model Viewer, or any WebGL framework. Files are deleted from our servers within 1 hour.
Frequently asked questions
- Are animations preserved in the conversion?
- Yes. Skeletal animations, blend shapes, and keyframe data from the FBX are converted to glTF animation format and embedded in the GLB.
- What happens to FBX materials?
- FBX materials are mapped to glTF PBR metallic-roughness. Standard properties like base color, normal maps, metallic, and roughness transfer cleanly. Autodesk-specific features without a glTF equivalent may be approximated.
- Can I view the GLB in my browser?
- Yes. Drop the GLB into any online glTF viewer, or load it with Three.js, Babylon.js, or Google Model Viewer. Modern browsers render GLB natively via WebGL.
- Is converting FBX to GLB 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.
