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.
glTF is the Khronos royalty-free standard for transmitting 3D scenes. The JSON variant keeps the scene description human-readable with geometry in sidecar buffers, and the ecosystem — Babylon.js, Unity, Unreal, Blender and the browser engines — treats it as the native interchange format for real-time 3D.
| FBX | glTF | |
|---|---|---|
| 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 | Real-time engines & web pipelines |
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 glTF 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 glTF result contains the converted geometry, hierarchy and flat colors, but it cannot recreate texture maps or animation that were dropped on import.

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.
