GLB

Binary glTF

GLB is glTF packed into a single binary file with its buffers and textures embedded. It is what you want for the web, for AR quick-look pipelines and for anything that has to travel as one file.

Extension: .glb
MIME type: model/gltf-binary

Opening a .glb file

If you landed here because something handed you a .glb file and nothing on your machine will open it, converting it to a format you already have a reader for is usually faster than installing new software. Every conversion above runs in this browser — the file is not uploaded, so it works on a locked-down work machine and on a file you are not allowed to send anywhere.
