glTF and GLB
glTF is the standard file format for carrying 3D models on the web; GLB is its single-file binary form.
Also known as: gltf · glb · 3D model format
It is often called "the JPEG of 3D": a format designed to be opened quickly by the browser rather than edited. Geometry, materials, textures and animation all travel in it.
The difference between the two is packaging. glTF keeps textures as separate files; GLB packs everything into one. GLB is usually the better choice for the web — one request instead of many.
Common questions
Can we convert our CAD files?
Yes, but conversion alone is not enough. CAD models carry far more detail than a browser needs; they have to be simplified as well (see LOD).
Which format should we ask our supplier for?
GLB. If that is not possible, glTF; and if neither, FBX or OBJ can be converted, though material settings are often lost on the way.
