GLB Explained – The Web 3D Standard

GLB (GL Binary) is the binary container format for glTF, the open standard for 3D content on the web. It bundles geometry, textures, materials and animations into a single file.

Why GLB?

GLB is the most efficient format for delivering 3D content on the web. It is supported by major platforms including Google, Facebook, Apple and all major game engines. A single GLB file contains everything needed to display a 3D model.

GLB vs OBJ vs STL

• GLB: Textures + materials + animations in one file. Best for web and AR.
• OBJ: Geometry + separate material files. Good for CAD exchange.
• STL: Geometry only. Best for 3D printing.
