Does the FBX need a separate texture folder?

No. Textures are embedded in the FBX, so the single file is self-contained.

Will a rigged and animated GLB keep its skeleton?

Yes. Bone hierarchy, skin weights and keyframe animation are written to the FBX. Blend shapes are the part that is not carried across.

Why is my FBX larger than the original GLB?

FBX embeds every texture map inside the file, and FBX is a verbose binary container. That growth is expected.

Format Information

Source 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.

Target 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.

About this conversion

This conversion turns a web-oriented glTF scene into the format DCC packages speak natively. GLBKit writes a single FBX with embedded textures, so the result opens in Maya, 3ds Max, Blender or MotionBuilder without a texture folder.

Why convert GLB to FBX

Send a glTF asset to a modeller who works in Maya or 3ds Max and wants a real scene file, not an imported one.
Hand a rigged or animated web asset to an animator for retargeting or cleanup in a DCC tool.
Keep everything in one file — FBX embeds its texture maps, so no sidecar folder travels with it.

What happens during the conversion

Geometry

Meshes, UVs, vertex colours and the node hierarchy are written out as a scene graph. Skinned meshes keep their bone hierarchy and skin weights, so a rigged GLB arrives in FBX still bound to its skeleton.

Materials and textures

Materials are written with their texture maps embedded in the FBX itself, so the file is portable on its own. The material model is flattened on export, which is why the result can look slightly different from a renderer that interprets the original glTF material graph.

Animation

Keyframe animation and morph targets are written. Clips are exported with the standard channels FBX supports; FBX-specific curve types that have no glTF equivalent are not carried across in the other direction, so exotic rig setups are the main risk.

Common use cases

Handing a web asset to a modelling or animation team for further work.
Importing a glTF character into a DCC tool for retargeting onto a different skeleton.
Producing a self-contained FBX for a pipeline that does not want loose texture files.

Limitations of this conversion

Blend shapes and Autodesk-specific property types are not carried across; a GLB with morph targets may not arrive with equivalent shape channels.
Materials are flattened on export, so PBR material graphs are not preserved node-for-node.
FBX is a large legacy format — a small GLB can become a much bigger FBX once textures are embedded.

How to convert GLB to FBX

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

Drop in your .glb

One self-contained file — nothing else needs to be uploaded.

STEP 2

Convert to FBX

The scene graph, skinning and animation are written with texture maps embedded in the file.

STEP 3

Open the FBX in your DCC tool

Check the material preview: FBX stores materials differently from glTF, so shading may need a small adjustment.
