Convert GLTF to FBX Online
Convert GLTF to FBX in seconds. glTF is the JSON-based "JPEG of 3D"; FBX's strength is this: the long-standing default asset format across game-engine pipelines. No software installation required — everything runs in your browser.

Why Convert GLTF to FBX?
FBX was built around moving textured, rigged, animated assets between DCC tools and game engines, which is precisely the gap glTF leaves open, since it's designed around human-readable, inspectable real-time 3D scene description instead.
glTF works well for human-readable, inspectable real-time 3D scene description, but has a real limitation: splits geometry, materials, and textures across separate files. Converting trades that for this: the long-standing default asset format across game-engine pipelines.
The short version: glTF is optimized for human-readable, inspectable real-time 3D scene description, FBX is optimized for moving textured, rigged, animated assets between DCC tools and game engines, and this converter exists for the moment those two needs don't line up.
How conversion works
- Upload your GLTF file.
- MiConvert converts it to FBX, aiming to preserve what makes FBX useful: the long-standing default asset format across game-engine pipelines.
- Download the converted FBX file.
- Use it directly with Maya, 3ds Max, Unity, Unreal Engine.
Key Conversion Features
- Produces output ready for Maya, 3ds Max, Unity, Unreal Engine, picking up right where Three.js, Babylon.js, and most modern web 3D viewers left off
- No local software installation required for either side — not Three.js, Babylon.js, and most modern web 3D viewers, not Maya, 3ds Max, Unity, Unreal Engine — everything runs in the cloud
- Bridges the gap between glTF's focus on human-readable, inspectable real-time 3D scene description and FBX's focus on moving textured, rigged, animated assets between DCC tools and game engines
- Purpose-built for the shift from human-readable, inspectable real-time 3D scene description to moving textured, rigged, animated assets between DCC tools and game engines, not a generic pass-through
- Free for files up to 50MB, 100MB for registered accounts

Frequently Asked Questions
What's the real difference between GLTF and FBX?
glTF is built around human-readable, inspectable real-time 3D scene description (the JSON-based "JPEG of 3D"). FBX is built around moving textured, rigged, animated assets between DCC tools and game engines instead (Autodesk's game and animation interchange format) — different enough that this is a genuine format conversion, not just a rename.
What software works with the converted FBX file?
FBX is used by Maya, 3ds Max, Unity, Unreal Engine. If you were working with Three.js, Babylon.js, and most modern web 3D viewers (which produces glTF), this conversion is the direct bridge between the two.
How long does the conversion take?
Most conversions finish in 10-30 seconds. Larger or more complex files can take up to a minute.
Is this conversion free?
Yes — free for files up to 50MB, with a 100MB limit for registered accounts, no subscription required.
Do I need Three.js, Babylon.js, and most modern web 3D viewers installed to convert my file?
No — the conversion happens entirely on our servers. You don't need Three.js, Babylon.js, and most modern web 3D viewers, and you don't need Maya, 3ds Max, Unity, Unreal Engine either unless you plan to open or edit the FBX result afterward.
