Convert GLB to FBX for Game Engines and DCC Tools
Upload a .glb and download one binary FBX with the meshes, skeleton, skin weights, shape keys and animation clips, plus the base color and normal map packed inside. Plan for one gap: the metallic-roughness texture from glTF is not linked in the FBX, so reconnect it in your engine.

Why convert GLB to FBX?
GLB is the binary form of glTF 2.0: a JSON scene description, the vertex buffers and the texture images in a single file, built for web viewers and AR. Many production tools still expect FBX: Unity reads GLB only after you add a glTF package, Maya and 3ds Max workflows are built around FBX, and many asset stores and rigging services ask for FBX uploads.
We do the conversion with Blender 5.1 running headless on our servers. Blender's glTF importer reads your file using the node transforms stored in it, without guessing a different rest pose, so skinned characters are not distorted on the way out. Blender's FBX exporter then writes a binary FBX and embeds the images. Before import we also decompress meshopt-compressed GLBs and re-encode WebP textures to PNG; Draco-compressed meshes are decoded by the importer itself.
What carries over: every mesh as its own FBX model, the material with its base color texture and normal map, vertex colors, the armature with its skin weights, morph targets as FBX blend shapes, and each glTF animation as a separate take. What changes: glTF stores metalness and roughness in one packed image, and that texture (along with ambient occlusion) is not linked in the FBX material. Blender's exporter also appends an extra end bone to every bone chain, and the FBX has no mesh compression, so it is usually larger than the GLB.
People search for this with phrases like glb to fbx with textures, with animation, or for Unity. The typical case is a model downloaded from a web gallery or built for an AR scene that now has to go into a game project, a Maya or 3ds Max scene, or a marketplace listing that only accepts FBX.
How to convert GLB to FBX
- Open the GLB in a glTF viewer first; if the textures show there, they are inside the file. If you have a .gltf with a separate .bin and image folder instead, zip them together and use our ZIP to FBX page.
- Upload the .glb, or several at once; the size limits for each plan are listed in the FAQ below.
- Blender imports the model and exports the FBX on our server, usually within a few seconds.
- Download the .fbx. The textures are embedded, so there is no image folder to keep next to it.
- Import it into your engine or DCC tool. In Unity, use Extract Textures in the model's Materials import tab if you want the images as separate assets, and pick the takes you need in the Animation tab.
- Reconnect the metallic and roughness channels by hand if your look depends on them. Our GLB to OBJ download includes every material image from the GLB as a file, which is a quick way to get that packed texture out.
What the GLB to FBX converter handles
- Skinned meshes keep the bind pose stored in the file, because the importer does not guess a new rest pose
- Each glTF animation becomes its own FBX take, with every bone keyed
- Base color texture and normal map embedded in the binary FBX; a base color tint is kept as the diffuse color
- Morph targets exported as FBX blend shapes, and vertex colors written to the mesh
- Accepts Draco-compressed, meshopt-compressed and WebP-textured GLB files
- Up to 10 files per batch, or 25 on Plus and 50 on Pro

GLB to FBX: common questions
Can I convert GLB to FBX with textures?
Yes. The base color texture and the normal map are embedded inside the FBX, so Unity, Unreal Engine, Maya and 3ds Max find them without a separate folder. If the glTF material multiplies the texture by a tint color, that tint is written as the FBX diffuse color. The metallic-roughness and occlusion textures are not linked in the FBX material, so set those up again after import if you need them.
Does GLB to FBX keep the animation and the rig?
Yes. The armature, the skin weights and every animation in the GLB are exported. Each glTF animation becomes a separate FBX take named after the armature and the clip, for example Armature|Walk. Expect one extra bone at the tip of every chain, named with an _end suffix; Blender's FBX exporter adds these leaf bones, and you can ignore or delete them in your engine.
How do I use the converted FBX in Unity?
Drag the .fbx into your Assets folder; Extract Textures on the Materials tab turns the embedded images into separate assets. Set the rig type on the Rig tab and choose takes on the Animation tab. Unity's standard shader does not read glTF's packed metallic-roughness map, so assign smoothness and metallic manually.
Why did I get "Imported model contains no exportable geometry or armatures"?
Blender opened the GLB but found nothing it could write: no mesh with vertices and no skeleton, only empty nodes, cameras or lights. This happens when a file is only a scene placeholder or its meshes were stripped during export. If a glTF viewer shows nothing either, re-export it from the original program with meshes included.
Why does it say an extension "is not available on this addon version"?
The GLB requires a glTF extension that Blender's importer does not support, for example KTX2/Basis Universal textures or Gaussian splat data. Re-export the model with plain PNG or JPEG textures and regular triangle meshes, then convert again. Draco, meshopt and WebP files are handled.
Which way is up in the FBX?
The FBX is written Y-up, the same axis convention glTF uses, so a model that stands upright in a glTF viewer should stand upright after import. If your scene expects a different axis or unit scale, adjust it in the importer settings rather than editing the mesh.
Is there a size or file count limit?
A single GLB can be up to 50 MB without an account, 100 MB with a free account, 200 MB with Plus and 1 GB with Pro. Each file has a 10-minute processing limit.
What happens to my GLB after conversion?
The conversion runs on our servers. Your uploaded GLB is deleted once processing ends, and the FBX can be downloaded through its link for 4 hours before an automatic cleanup removes it.
