Converting Wavefront OBJ to glTF Binary (GLB)
OBJ is a portable, widely edited mesh format, but it often needs a separate .mtl file and isn't ideal for the web. GLB bundles everything into one binary that browsers, AR and game engines read natively. Converting OBJ to GLB gives you a single, web-ready file.
What's kept and what's dropped
Mesh geometry and UV coordinates convert across. Materials from a linked .mtl aren't loaded here, so the GLB carries the mesh with a standard material — reassign textures afterward if needed.
