GLB 3D Model (.GLB)
GLB (GL Transmission Format Binary) is the binary container version of glTF 2.0, packaging the JSON scene description, binary geometry buffers, and texture images into a single self-contained file. Developed by the Khronos Group, it is designed as the "JPEG of 3D" for efficient transmission and loading of 3D content. GLB supports PBR (Physically Based Rendering) materials, skeletal animation, and morph targets.
Advantages of GLB 3D Model
What the GLB format does well, and why you might choose it.
- Single self-contained file with geometry, textures, and materials
- Optimized for fast loading in web browsers and real-time 3D applications
- Supports PBR materials, skeletal animation, morph targets, and scene hierarchy
Limitations of GLB 3D Model
What the GLBformat doesn't do well, and when to choose another format.
- Relatively newer format with less support in legacy 3D software
- Binary format that is not human-readable for debugging or manual editing
- Texture compression within GLB varies across viewers and engines
What GLB files are used for
- Web-based 3D content delivery with Three.js, Babylon.js, and WebXR
- AR and VR application 3D asset distribution
- Real-time 3D visualization in e-commerce and product configurators

Frequently asked questions about GLB
What is a .GLB file?
GLB (GL Transmission Format Binary) is the binary container version of glTF 2.0, packaging the JSON scene description, binary geometry buffers, and texture images into a single self-contained file. Developed by the Khronos Group, it is designed as the "JPEG of 3D" for efficient transmission and loading of 3D content. GLB supports PBR (Physically Based Rendering) materials, skeletal animation, and morph targets.
What is the MIME type of GLB?
The official MIME type for GLB files is model/gltf-binary. This is the value web servers and applications use to identify the format when transferring files.
What category does GLB belong to?
GLB is a 3D Model Converter format. Files in this category share common conversion paths and use cases.
How do I open a .GLB file?
GLB files are typically opened by software that natively supports the GLB 3D Modelformat. If you don't have a compatible application, the most reliable approach is to convert the file to a more universal format using the converters listed above. Most GLB 3D Model files convert to widely-supported alternatives in seconds.
