What Is an OBJ File?
OBJ (Wavefront OBJ) is one of the most widely adopted 3D model file formats. Developed by Wavefront Technologies, it stores 3D geometry including vertices, faces, surface normals, and material definitions. Unlike binary formats like FBX, OBJ files are plain-text, making them easy to parse and universally supported across 3D software, game engines, and 3D printers.

OBJ vs Other 3D Formats
| Format | Strengths | Best For |
|---|---|---|
| OBJ | Universal, plain text, materials | Sharing, 3D printing, general use |
| STL | Simple, industry standard | 3D printing (no color) |
| FBX | Animation, rigging, materials | Game engines, animation |
| glTF/GLB | Modern, compact, PBR materials | Web, AR/VR, real-time rendering |
