OBJ files exist as 2 different types. Please find information about each of them below.
Type 1: Wavefront 3D Object File

OBJ is a geometry definition file format developed by Wavefront Technologies for its Advanced Visualizer. The open file format represents 3D geometry – vertex positions, texture coordinates, vertex normals, and polygon faces. Vertices are stored counter-clockwise by default.
An OBJ file contains a 3D object with coordinates, textures, polygons, and other information. OBJ files may store references to MTL files that contain surface materials. CAD users see OBJ as a universal 3D format since many programs use the text-based format.
Object files define geometry and properties for objects in Wavefront’s Advanced Visualizer. They transfer geometric data between the Visualizer and applications. Object files can be ASCII (.obj) or binary (.mod).
You can open and edit OBJ files in 3D modeling software like Autodesk Maya, 3ds Max and Blender. These let users manipulate the 3D model geometries. To edit an OBJ file, open it, select objects to change, edit them, and save changes. You can also convert OBJ files to formats like FBX.
The widely used OBJ format contains references to MTL files with surface materials. It is considered a universal 3D format for editing applications. OBJ files are often used for 3D printing. Printer software slices OBJ files into print instructions per layer.
OBJ was developed by Wavefront for its Advanced Visualizer app to store geometric objects. Wavefront is known for modeling, animation and image editing tools for workstations. OBJ files often use the .obj extension per UNIX naming convention. The latest version is v3.0.

An OBJ file is a standard 3D image format. It is exported and opened by various 3D editing programs. The OBJ file stores a 3D object. This includes 3D coordinates, textures, polygonal shapes, and other object data. An OBJ file may also store references to .MTL files. These .MTL files contain the 3D object’s surface colors or textures.
We have some online .OBJ file tools. These let you view, edit, convert, merge, split and compare OBJ files without installing anything. Click the links to see the full details for each tool.
OBJ files store 3D model data. Many 3D models are saved as OBJ files. OBJ format is commonly used in 3D printing, video games, and computer assisted design. The OBJ file contains the raw data to create the 3D object. This includes the mesh, textures, lighting, and more to define how the object should look.
The OBJ format is widely used by 3D editing programs. The OBJ file usually references .MTL files. These .MTL files define the object’s surface qualities. Here is a list of software that can open OBJ files.
The Object Module Format (OMF) is an old object file format. It was used for software running on MS-DOS. Programmers wrote code in various languages. Then a compiler created object files from the source code. Finally, the object files were linked into a final executable file. MS-DOS programs were linked OMF files. Windows programs were linked COFF files instead.
The OBJ format is considered universal for 3D editing software. OBJ files commonly reference .MTL files for surface textures. Here is a list of software that can open Wavefront 3D OBJ files.
