Wavefront OBJ 3D Model (.OBJ)
OBJ (Wavefront Object) is a widely used plain-text 3D model format that stores geometry including vertices, texture coordinates, normals, and polygon faces. Developed by Wavefront Technologies, it supports polygonal meshes with optional material and texture references through companion .mtl (Material Template Library) files. OBJ is one of the most universally supported 3D interchange formats.
Advantages of Wavefront OBJ 3D Model
What the OBJ format does well, and why you might choose it.
- Widely supported by virtually all 3D modeling, rendering, and game development tools
- Plain-text format that is human-readable and easy to parse or generate
- Supports texture coordinates, normals, and material references
Limitations of Wavefront OBJ 3D Model
What the OBJformat doesn't do well, and when to choose another format.
- No support for animation, rigging, or scene hierarchy
- Plain-text format results in large file sizes for complex models
- Material and texture information requires separate .mtl and image files
What OBJ files are used for
- 3D model interchange between different modeling and rendering software
- 3D printing with texture and material information
- Game development asset pipelines and 3D content creation

Frequently asked questions about OBJ
What is a .OBJ file?
OBJ (Wavefront Object) is a widely used plain-text 3D model format that stores geometry including vertices, texture coordinates, normals, and polygon faces. Developed by Wavefront Technologies, it supports polygonal meshes with optional material and texture references through companion .mtl (Material Template Library) files. OBJ is one of the most universally supported 3D interchange formats.
What is the MIME type of OBJ?
The official MIME type for OBJ files is model/obj. This is the value web servers and applications use to identify the format when transferring files.
What category does OBJ belong to?
OBJ is a 3D Model Converter format. Files in this category share common conversion paths and use cases.
How do I open a .OBJ file?
OBJ files are typically opened by software that natively supports the Wavefront OBJ 3D Modelformat. If you don't have a compatible application, the most reliable approach is to convert the file to a more universal format using the converters listed above. Most Wavefront OBJ 3D Model files convert to widely-supported alternatives in seconds.
