The GLB file format is the binary version of the GLTF (GL Transmission Format – a standardized format for transmitting 3D models and scenes), a widely used standard for 3D models. Unlike GLTF, which references external resources, a GLB file stores all geometry, materials, textures, and animations in a single, compact file.
Because of this, GLB is:
- Efficient – smaller file size and faster loading.
- Portable – everything bundled together, no missing textures.
- Versatile – supported by most 3D applications, AR/VR platforms, and web browsers.
In practice, GLB is often used for sharing 3D models online, in product visualization, virtual showrooms, and interactive 3D experiences.
