How do I convert an FBX file to GLB?

Upload your .fbx file to the converter, choose GLB as the output format, optionally enable texture compression (e.g., KTX2) or animation export, then click Convert. Download the .glb file, which bundles all meshes, textures, and animations into one binary container.

Why should I convert FBX to GLB instead of keeping FBX?

FBX is an Autodesk interchange format with large file sizes and proprietary dependencies. GLB is the binary glTF format, an open standard optimized for real-time engines and web browsers. Converting to GLB significantly reduces file size, improves load times, and ensures compatibility with Three.js, Babylon.js, AR/VR viewers, and modern 3D pipelines.

What happens to my materials, textures, and animations during conversion?

The converter preserves PBR materials, base color, normal, metallic/roughness maps, and skeletal animations. Geometry and UV maps are retained; textures are re-encoded to WebGL-friendly formats (e.g., PNG/JPEG, or KTX2 for compressed textures). Unsupported FBX features like custom physics properties or embedded scripts are discarded. Transparency and double-sided materials map directly to glTF alpha modes.

FBX

Autodesk FilmBox

Source Format

FBX is a proprietary 3D asset exchange format developed by Kaydara and Autodesk. Widely used in video game development and cinematic VFX, it stores complex 3D geometry, UVs, bones, skinning, morph targets, and animation curves.

Category: 3D Graphics

MIME Type: application/octet-stream

Developer: Autodesk

Best For: Game engine imports, character animation, and film/VFX production.

✨

GLB

Binary glTF Container

Target Output

GLB is the self-contained binary container representation of glTF. It bundles the 3D scene hierarchy, shaders, buffers, geometry, and embedded texture images into a single compact binary file optimized for instant web transfer.

Category: 3D Graphics

MIME Type: model/gltf-binary

Developer: Khronos Group

Best For: Augmented Reality (AR), 3D web viewers, and cross-platform 3D asset sharing.

💡 Technical Guide & Conversion Insights

Why Convert FBX to GLB?
