GLB File Format

glTF Binary Model category

GLB is the compact binary form of glTF — "the JPEG of 3D": one file carrying geometry, materials and textures, made for the web, AR and game engines.

Typical use: GLB is what three.js, model-viewer, Unity and AR quick-look consume — the best choice for showing models on websites.

About the GLB format

GLB is the binary form of glTF 2.0 — the format the Khronos Group designed as “JPEG of 3D”. One self-contained file carries geometry, a full scene hierarchy, PBR materials with textures, skeletal animation and morph targets. It is the native asset format of three.js, Unity, Unreal, Blender and WebXR.

Converting to GLB is usually the upgrade path from OBJ/STL: materials become physically based and embedded, and scenes become portable in a single file. One honest caveat: Draco-compressed GLBs save space but many loaders need explicit decoder setup — plain GLB plays everywhere unconditionally.

Strengths

✓ PBR materials, hierarchy and animation in one file
✓ The web/AR standard — loads natively in three.js
✓ Compact binary with texture embedding

Limitations

✗ Mesh-only: no CAD solids or NURBS
✗ Older niche tools may not know glTF

Structure: Scene graph + mesh + animation
Materials: PBR, textures embedded
Compatibility: Web/AR/game engines native
Best for: Web, AR and full 3D scenes
