Does a rigged FBX stay rigged after conversion?

Yes. The bone hierarchy, skin weights and keyframe animation are carried into the GLB, and morph targets are carried too.

What about blend shapes?

They are not read. If your FBX uses blend shapes for facial or body deformation, that data will not appear in the GLB.

Why does my material look slightly different?

FBX and glTF do not share a shading model. The material is mapped onto glTF's metallic-roughness workflow, so an FBX built around a different model can need a small correction in the result.

Format Information

Source Format

FBX.fbx

FBX (Filmbox Scene)

FBX is Autodesk's scene format, written by Maya, 3ds Max and MotionBuilder. It is a compact container for a whole DCC scene, which is why it is the usual hand-off format when a model comes back from a modelling or animation package.

What it carries: Meshes, UVs, vertex colours, materials with embedded texture maps, a bone hierarchy, skinning, and keyframe animation clips. Blend shapes and Autodesk-specific property types are not read by this converter.

Target Format

GLB.glb

GLB (glTF Binary)

GLB is the binary packaging of glTF 2.0. Meshes, materials, image textures, animation and the node hierarchy are all written into one file, so an asset can be dropped into an engine or a web page without shipping a folder of sidecar files.

What it carries: Vertex positions, normals, UVs and vertex colours, full PBR materials (base colour, metallic/roughness, normal, occlusion, emissive), embedded image textures, node hierarchy, skinning, morph targets, keyframe animation, cameras and lights.

About this conversion

The bridge from a DCC scene to the web. An FBX from Maya, 3ds Max or Blender is read — meshes, materials, embedded textures, skeleton and animation — and written as one self-contained GLB that a browser or engine can load in a single request.

Why convert FBX to GLB

Put an Autodesk-scene asset on the web or in a game engine without shipping a folder of textures.
Hand a rigged, animated FBX character to a three.js, Unity or Godot project.
Replace a verbose binary FBX with a single file that caches and versions cleanly.

What happens during the conversion

Geometry

Meshes, UVs, vertex colours and the node hierarchy are written into the GLB scene graph, with FBX node transforms preserved as glTF nodes rather than baked. A skinned model keeps its bone hierarchy and skin weights, so the character arrives still rigged.

Materials and textures

FBX materials carry embedded texture maps, and those become embedded glTF PBR textures inside the GLB. The material is mapped onto glTF's metallic-roughness model; where the FBX material relied on a shading model glTF does not express, the result falls back to glTF defaults and may need a small shading adjustment.

Animation

Keyframe animation, skinning and morph targets are written. This is the one direction where FBX genuinely has the richer format, so a well-authored rig survives the trip intact.

Common use cases

Shipping a Maya or 3ds Max character to a real-time project.
Publishing an animated asset to the web as a single file.
Handing a rig to an engine that supports only glTF.

Limitations of this conversion

Blend shapes and Autodesk-specific property types are not read, so an FBX relying on them loses that data.
The glTF material model is metallic-roughness. An FBX built around a different shading model may not match exactly after conversion.
Objects hidden in the FBX are not written to the GLB, so a scene that uses visibility toggles produces a smaller file.
Large embedded texture sets make for a large GLB; nothing is downscaled except images beyond 4096 px on their longest edge.

How to convert FBX to GLB

Three steps in the browser. Nothing is uploaded to a server, so an unwieldy file is limited only by your own device's memory.

STEP 1

Upload your .fbx

A single FBX is normally enough. If your file references external textures, zip the .fbx and the images together.

STEP 2

Convert to GLB

Meshes, materials, embedded textures, skinning and animation are written into one binary glTF.
