Free 3D converter

Convert FBX to GLB

Drop a FBX file and download it as GLB. The conversion runs in your browser, so the file never leaves your device. It keeps the exact shape, materials and textures and animation.

Free, no sign-up, and your file stays on your device.

Converted to GLB in your browser. Nothing is uploaded.

GLB, glTF, OBJ, STL, PLY, FBX or 3MF, up to 300 MB. Add .mtl, .bin and texture files alongside.

How to convert FBX to GLB

  1. Add your FBX

    Drop the FBX file, with its textures if it has separate ones.

  2. Check the preview

    Turn the model and check what will be kept before converting.

  3. Download the GLB

    The .glb is written in a second or two for most models.

When to convert FBX to GLB

  • To put it on the web

    GLB is what three.js, Google's <model-viewer> and most web viewers load: one file, textures included.

  • For Blender and Godot

    Both import glTF natively, with materials, so there is no .mtl or texture folder to keep together.

  • To keep an animation

    GLB stores skeletons and animation clips, so a Mixamo FBX keeps its motion.

The two formats

FBX

Autodesk FBX

FBX is Autodesk's proprietary interchange format, originally Kaydara's FiLMBOX from the 1990s. It carries meshes, materials, skeletons and animation, which made it the default for game engines and Mixamo.

Usually comes from
Mixamo, Maya, 3ds Max, game asset stores and Unity or Unreal projects
Opens in
Unity, Unreal Engine, Godot, Roblox Studio, Blender, Maya, 3ds Max and Mixamo
Units
Centimetres times a scale factor stored in the file
Up axis
Set in the file

GLB

Binary glTF 2.0

GLB is the single-file, binary form of glTF 2.0, the open format the Khronos Group published in 2017 for delivering 3D assets. Mesh, materials, textures and animation all travel in one file.

Usually comes from
AI 3D generators (including PhotoGenius), Sketchfab downloads, web 3D projects and game asset stores
Opens in
Blender, Godot, three.js and most web viewers, Android's Scene Viewer, Bambu Studio and UltiMaker Cura, Unreal's glTF importer, and Unity with the glTFast package

Questions

Something else? Ask us and a person will answer.

Is this FBX to GLB converter free?

Yes. There is no account, watermark or limit on conversions. It accepts files up to 300 MB; how large a model your browser can handle depends on your device's memory.

Is my file uploaded?

No. The conversion runs in your browser with the open-source three.js loaders and exporters, so your FBX never leaves your device.

Does the GLB keep textures and animation?

Yes, everything the FBX has that glTF supports: geometry, UVs, materials and textures embedded in the file, plus skeletons and animation clips.

Are FBX textures included?

Textures embedded in the FBX are. If yours sit next to the FBX as separate files, select them together with it.

Can I make a 3D model from a photo instead?

Yes. PhotoGenius turns a photo or a text prompt into a textured GLB with Rodin Gen-2.5, Rodin Gen-2.5 Fast, Tripo H3.1, TRELLIS.2, Rodin Gen-2 or Hunyuan3D 3.1, which you can then convert here. See Image to 3D model.

Turn a photo into a 3D model

Rodin Gen-2.5, Rodin Gen-2.5 Fast, Tripo H3.1, TRELLIS.2, Rodin Gen-2 or Hunyuan3D 3.1 builds a textured GLB from one image. The price shows before you run it.
