FBX vs GLB— what's the difference?

FBX.fbx

Autodesk's proprietary interchange format — the de-facto standard for moving rigged, animated characters between Maya, Max, Blender, Unity, and Unreal.

Strengths
  • Carries skeletal animation, blend shapes, cameras, lights
  • Supported by every major DCC and game engine
  • Binary or ASCII flavours
Limitations
  • Closed, Autodesk-controlled spec — SDK-only for authoritative reads
  • No universal web viewer — typically converted to GLB for the browser
Typical use: Character animation handoff, game engine import, DCC transfer
GLB.glb

Binary glTF — the JPEG of 3D. Self-contained, small, and loads natively on the web, in AR, and in every modern 3D engine.

Strengths
  • Everything (geometry, textures, materials, animations) packed into one file
  • Tiny and fast — designed for streaming and web delivery
  • Native support in Blender, Unity, Unreal, three.js, <model-viewer>, Android ARCore…
  • PBR materials (metallic-roughness) render consistently everywhere
Limitations
  • Binary — not hand-editable
  • Less common in traditional CAD pipelines
Typical use: Web 3D, AR/VR, real-time engines, e-commerce product views

How to convert FBX to GLB

  1. 1
    Drop a .fbx file onto the page. Binary or ASCII FBX both work. Everything runs locally.
  2. 2
    Preview the model in 3D. Use the Scene Tree to walk the hierarchy and hide parts you don't want to export.
  3. 3
    Click Download .GLB. Load the result into three.js, <model-viewer>, Unity, Unreal, or Android ARCore.

FAQ

Why convert FBX to GLB?

FBX is great for DCC handoff, but no browser speaks it. GLB is the web-native 3D format — tiny, self-contained, render-anywhere. If you're publishing a model online, GLB is almost always what you want.

Is my FBX uploaded?

No. The file is parsed by Three.js' FBXLoader in your browser, then re-exported as GLB by GLTFExporter. Your asset never leaves the machine.

Does animation carry over?

Skeletal animations and blend shapes are preserved by GLTFExporter when present. Complex rig constraints (IK, HIK, Maya-specific nodes) may not translate cleanly — test in your target engine.

What happens to materials and textures?

Standard FBX materials (diffuse / normal / specular) are mapped to glTF's PBR metallic-roughness workflow. Embedded textures are packed into the GLB; external textures are referenced and may need to be shipped alongside.

Can I preview the GLB in AR?

For Android ARCore, drop the GLB into Scene Viewer. For iOS AR Quick Look you need USDZ specifically — the 3D viewer on this site can export USDZ directly from the loaded FBX.
