# GLB file

Also called GLB, glTF

GLB is glTF, the web 3D format, in a single file. It loads in three.js, Babylon.js and Google's model-viewer, for the web, AR and real-time 3D.

## In more detail

A .gltf file with a separate .bin file cannot open in a browser on its own. Use the single .glb file instead. Blender and Godot also open GLB.

## How we measure it

Our 3D files include GLB. Our tools read your own .glb, or a .gltf with its data inside it. They do not read Draco or meshopt compression.
