FBX to glTF Converter
Processing entirely on your device — large files may take a moment.
Convert .gltf to GLB when you need one portable file, or to OBJ/STL for tools and 3D printers that expect those. If your files are still in FBX format, this page is the shortcut: FBX is Autodesk's de-facto standard for exchanging animated 3D scenes between DCC tools (Maya, 3ds Max, Blender). Binary or ASCII; the browser conversion supports geometry, hierarchy and materials embedded in the file.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.
How FBX compares to glTF
| FBX | glTF | |
|---|---|---|
| Structure | Scene graph + animation | JSON scene + external buffer |
| Materials | Phong/lambert + textures | PBR, textures as separate files |
| Compatibility | Autodesk + game engines | All glTF loaders |
| Best for | Animated 3D interchange | Editing and debugging assets |

About the FBX format
FBX is Autodesk's proprietary interchange format and the lingua franca between Maya, 3ds Max, Blender and game engines. It carries meshes, skeletal animation, blend shapes, cameras and materials — the most complete (and most closed) of the common 3D formats.
Game engines want FBX converted to glTF/GLB for web delivery, while static geometry extracts cleanly to OBJ/STL. The browser conversion here supports geometry, hierarchy and embedded materials from both ASCII and binary FBX files.
+ Strengths
- ✓The DCC-industry standard (Maya/Max/Blender)
- ✓Animation, skinning and cameras included
- ✓Both ASCII and binary forms
! Limitations
- −Proprietary — spec is undocumented
- −Version differences bite converters
- −Web pipelines prefer glTF/GLB
About the glTF format
glTF in its JSON form (.gltf) is the readable side of the glTF 2.0 family: scene graph, meshes, materials, cameras and animations described in JSON, with binary geometry in a separate .bin buffer and textures as their own image files. Seeing the structure as text is genuinely useful when you are debugging an asset pipeline or hand-editing a material.
The trade-off is portability: a .gltf is only self-contained when its buffers are embedded as data URIs, which bloats the file. Everywhere you just want to ship or drop a model into a viewer, GLB is the better answer — and that is exactly what the gltf-to-glb page does for you, in your browser, without uploading the model.
+ Strengths
- ✓Human-readable JSON structure
- ✓Same PBR materials and scene data as GLB
- ✓Easy to diff, debug and hand-edit
! Limitations
- −Usually needs separate .bin and texture files
- −Breaks when files are moved apart
- −Larger than GLB once buffers are embedded
Why convert FBX to glTF?
There is a concrete reason this conversion exists: Proprietary — spec is undocumented glTF sidesteps that — Human-readable JSON structure If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this FBX to glTF converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Will my model look the same as a GLB?
Geometry, hierarchy and standard materials convert faithfully. Note that Draco-compressed GLB files and exotic extensions are not supported — export those as plain GLB from your original tool first.
Will my glTF model keep its colors and textures?
Only if glTF can store them. Geometry converts faithfully; appearance data survives only when the target format has a place to put it. For full materials, GLB is usually the right target.
How large can the FBX file be?
Everything runs on your device, so memory is the only ceiling. Dense meshes with millions of triangles convert fine on a desktop computer, just over a slightly longer coffee break.
