About These Formats
Wavefront OBJ
OBJ is a simple, human-readable text format that stores 3D geometry (vertices, faces, texture coordinates, and normals). It is one of the most universally supported formats.
Used with
Blender, Maya, Cinema 4D, 3ds Max, ZBrush, and virtually any 3D application.
GL Binary
GLB is the binary form of the GLTF format — a compact, web-optimized container that bundles geometry, textures, and animations into a single file.
Used with
Three.js, Babylon.js, React Three Fiber, Unity, Unreal Engine, Blender, AR/VR applications.
When to Convert OBJ to GLB
Convert OBJ to GLB when you need a web-ready, self-contained 3D asset. GLB is the preferred format for Three.js, React Three Fiber, Babylon.js, and Needle Engine. It bundles geometry, textures, and animations into a single binary file, making it ideal for fast web loading and AR/VR applications.
