Convert Autodesk FBX into the open glTF standard, as editable JSON for web and engine pipelines. This converter runs entirely in your browser: the file is processed on your own device and never uploaded.
Why convert FBX to GLTF?
Convert Autodesk FBX into the open glTF standard, as editable JSON for web and engine pipelines.
How it works
Drop your .fbx file above and download the .gltf. The conversion engine (Assimp, compiled to WebAssembly) runs inside the page, so it works the same on Windows, macOS, Linux and ChromeOS without installing anything.
FBX vs GLTF
FBX (Autodesk Filmbox): FBX is Autodesk’s proprietary interchange format for meshes, materials, skeletons and animation. It is the de-facto format for moving animated assets between content tools and game engines. Used by: Maya, 3ds Max, MotionBuilder, Unity, Unreal Engine, and asset stores such as Mixamo.
glTF (GL Transmission Format): glTF is the Khronos Group’s open standard for delivering 3D models, often called “the JPEG of 3D”. A .gltf file is JSON that describes meshes and physically based (PBR) materials, with binary data and textures alongside or embedded. Used by: three.js, Babylon.js, Blender, Sketchfab, and developers who want a readable, editable model file.
Quality notes
Meshes, materials and hierarchy convert; animation and skinning are carried where Assimp can map them. Check complex rigs after conversion. glTF output is a .gltf file plus a .bin file with the geometry, so the download is a ZIP containing both — keep them together.
Common use cases
Inspecting an FBX asset’s structure; moving game assets into open-source engines like Godot.
Frequently asked questions
Does Godot support glTF?＋
Yes — glTF is Godot’s recommended import format.
Are animations kept?＋
Where Assimp can map them; preview the result.
Is FBX uploaded?＋
No.
Why do materials look different?＋
glTF uses PBR materials, so FBX shading is approximated.
