OBJ File

What are OBJ files and how to open them

Are you having problems opening an OBJ file or just wondering what they contain? We explain what these files are used for and show you software that we know can open or otherwise handle your files.

What is an OBJ file?

OBJ files have multiple uses, and Blender 3D Object is one of them. Read more about the others further down the page.

Blender 3D Object

These files hold 3D objects created with Blender, a 3D animation software application. They can contain texture maps, 3D coordinates, and other 3D object data.

How to open OBJ files

We have identified one OBJ opener that is compatible with this specific type of OBJ file.

All known file formats using extension .OBJ

While Blender 3D Object is a popular type of OBJ-file, we know of 14 different uses of the .OBJ file extension. Different software may use files with the same extension for different types of data.

Common Object File Format (COFF) Object File

Several compilers generate these files on the Windows platform, e.g., C and C++ compilers. When the compiler processes a source code file, a .obj file is generated. When all source code files have been compiled to .obj files, the .obj files are linked together to the resulting .exe executable file or .dll library file.

While we have not verified the apps ourselves yet, our users have suggested 10 different OBJ openers which you will find listed below.

Relocatable Object Module Format (OMF) Object File

The Relocatable Object Module Format (OMF) is an object file format used for software running on the MS-DOS Operating System.

Programmers write software in various programming languages and use a compiler to generate the executable application file. Each of the source code files is compiled into an object file. At the end of the compilation process, all object files are linked together into the final executable application file.

MS-DOS executables consist of linked OMF object files, whole Windows executables consist of linked COFF object files (find a separate entry for that on this page).

More file formats using the OBJ extension

Through our research of OBJ files, we know that the following formats exist. However, we have not yet analyzed them in detail.

  • 3D Construction Kit Object
  • CADRazor 3D Model
  • Flashback Object
  • LightWave 3D Object
  • MeshLab Mesh
  • Opticks Object
  • TransFORTH Compiled Object Code
  • UVMapper Object
  • Wavefront Object
  • World Construction Set Object
  • X-CAD Modifier Table

Various apps that use files with this extension

These apps are known to open certain types of OBJ files. Remember, different programs may use OBJ files for different purposes, so you may need to try out a few of them to be able to open your specific file.
