OBJ vs FBX vs GLTF
Compare OBJ, FBX, and GLTF files for games, web previews, animation, and general 3D model exchange.
OBJ is simple and widely supported
OBJ is useful when you need a basic mesh format that opens in many 3D tools. It is common for static models, props, and general exchange.
FBX is common for games and animation
FBX can carry mesh data, hierarchy, materials, animation, and rig information. It is often used in Unity, Unreal Engine, Maya, and Blender workflows.
GLTF is strong for web and realtime previews
GLTF is designed for efficient runtime delivery. It is a strong choice for web 3D viewers, ecommerce previews, and lightweight interactive scenes.
Pick based on the target tool
Use OBJ for broad compatibility, FBX for animation and game pipelines, and GLTF for web or realtime viewing.
