How to convert FBX to GLB
- Drop your .fbx file into the box above, or click Choose file.
- Check the 3D preview, size and triangle count.
- Make sure GLB is selected as the output format. Adjust scale or up-axis if needed.
- Click Download. The .glb file is created instantly on your device.
Why convert FBX to GLB?
GLB is the modern, open alternative to FBX for web, AR and real-time apps. Meshes, materials, textures, hierarchy and animations are carried over to glTF 2.0.
What changes in the conversion
- Geometry is preserved. Every triangle, with all object transforms applied, ends up in the new file.

About the formats
FBX (Filmbox) was originally developed by Kaydara and now owned by Autodesk. It is a proprietary scene format that stores meshes, materials, skeletons and animation. It is the usual exchange format for animated characters between Maya, 3ds Max, Blender, Unity and Unreal Engine.
GLB (binary glTF) was defined by the Khronos Group as the single-file binary form of glTF 2.0. It packs meshes, PBR materials, textures, scene hierarchy and animations into one compact file. It is the standard for 3D on the web, AR viewers, e-commerce product views and game engines.
Frequently asked questions
Is this converter free?
Yes. You can convert FBX to GLB for free – up to 3 conversions a day, with no sign-up and no watermark. If you need more, Pro gives you unlimited conversions and batch conversion (free for 7 days).
Are my files uploaded to a server?
No. The conversion runs entirely in your browser using WebAssembly and JavaScript. Your model never leaves your computer, which also makes it safe for confidential parts and patient data.
Is there a file size limit?
There is no fixed limit. Files of a few hundred megabytes work on a typical laptop; the practical limit is your device's memory.
