Free FBX (.fbx) to GLB (.glb) converter — running entirely in your browser. No upload, no signup, no file limits: your files never leave your device.

FBX is Autodesk’s proprietary scene format and the long-time workhorse of game development and animation pipelines. It carries meshes, rigs, skinning, animation takes and materials between tools like Maya, 3ds Max, Blender, Unity and Unreal.
GLB is the single-file binary packaging of glTF, the "JPEG of 3D". One file carries geometry, materials, textures and animations, optimized for fast GPU loading. It is the standard for web 3D, AR on Android, e-commerce product viewers and real-time applications.
| FBX | GLB | |
|---|---|---|
| Geometry | Polygon mesh scenes | GPU-ready triangle mesh |
| Units | Yes | Meters by spec |
| Colors & materials | Materials & textures | Full PBR materials |
| Animations | Yes — rigs & takes | Yes |
| Typical use | Game & animation pipelines | Web, AR & real-time delivery |
Yes — free with no accounts, no watermarks and no file-size limits. Conversion runs on your own machine, so there are no server costs behind it.
No. The converter runs entirely in your browser using WebAssembly. Your .fbx file never leaves your device, which makes it safe for confidential designs.
Yes — parts and assembly hierarchy are preserved where GLB supports them, and you can optionally merge everything into a single mesh during conversion.
Yes. Every converted model opens in the built-in 3D viewer with an assembly tree, display modes and section views, so you can inspect the result first.
FBX can contain textures and animation, but this converter carries geometry, hierarchy and one flat base color per part; texture maps, rigs and animation tracks are omitted. The GLB result contains the converted geometry, hierarchy and flat colors, but it cannot recreate texture maps or animation that were dropped on import.
Which 3D format should you ship on the web? A practical comparison of glTF, GLB and OBJ — file size, materials, loading speed — with free conversion tools.
Most online CAD converters upload your intellectual property to unknown servers. Learn what actually happens to uploaded files and how client-side conversion avoids the risk.
