About the GLB format

glTF was created by the Khronos Group as the 'JPEG of 3D', a compact format for showing models in real time. GLB packs the whole model, including textures, into one binary file, which is why websites, three.js, Babylon.js and Android's AR viewer use it.

3D printers, slicers and many desktop programs do not take GLB, so it is converted to STL or 3MF for printing and to OBJ or FBX for editing. Models from other formats are converted to GLB to show them on a website.
