How do I convert an FBX file to GLTF?

Upload your FBX file to LetsConvert, choose GLTF as the output format, and click Convert. The tool will process the 3D model and provide a downloadable .gltf file with its associated textures and binary buffer in a zip archive. For a single-file output, select GLB instead.

Why should I convert FBX to GLTF instead of using FBX directly?

GLTF is the standard format for 3D models on the web and is optimized for real-time rendering. Unlike FBX, which is often tied to software like Maya or 3ds Max, GLTF loads efficiently in browsers, Unity, and three.js, and often reduces file size by using compressed geometry and textures.

How does the conversion handle animations, textures, and scene hierarchy?

The converter preserves skeletal animations, PBR material parameters, embedded textures, and node hierarchy. Geometry is re-encoded to GLTF's efficient buffer layout, and textures are kept in their original format when supported; otherwise, they're recompressed to a web-friendly format like PNG or JPEG. Color spaces and transparency are mapped correctly to GLTF's PBR model.

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.

✨

GLTF

GL Transmission Format (JSON)

Target Output

glTF is the open royalty-free standard designed by Khronos Group as the 'JPEG of 3D'. It minimizes runtime asset sizes and GPU processing overhead for real-time web rendering (WebGL/WebGPU) and AR/VR applications.

Category: 3D Graphics

MIME Type: model/gltf+json

Developer: Khronos Group

Best For: Web 3D applications, e-commerce AR preview, and mobile games.
