Download 3D OBJ Free: A Guide to Finding and Using Free 3D Models
If you are interested in 3D modeling, animation, or printing, you may have come across the term OBJ file. OBJ files are one of the most common and versatile file formats for storing and exchanging 3D models. They can be used for various purposes, such as creating realistic renderings, adding details to your designs, or printing them in full color.

In this article, we will explain what an OBJ file is, why it is useful, how to download free 3D OBJ models from various websites, and how to use them in different 3D software. By the end of this article, you will have a better understanding of the OBJ file format and how to take advantage of it.
What is an OBJ File and Why is it Useful?
The Basics of OBJ File Format
An OBJ file is a text file format that stores a description of the surface of a 3D object, composed of polygons, curves, vertices, texture maps, and other object information. It is a vector file that can be scaled and has no maximum file size. It is often used as an exchange format for 3D graphics and multi-color 3D printing. It can be edited in a text editor or various 3D image editing programs.
The OBJ file format was developed by Wavefront Technologies (designers of 3D Maya modeling software) for its Advanced Visualizer package. The file format is open and has been adopted by other 3D graphics application vendors. The OBJ file format is a simple data-format that represents 3D geometry alone namely, the position of each vertex, the UV position of each texture coordinate vertex, vertex normals, and the faces that make each polygon defined as a list of vertices, and texture vertices. Vertices are stored in a counter-clockwise order by default, making explicit declaration of face normals unnecessary. OBJ coordinates have no units, but OBJ files can contain scale information in a human readable comment line.
The Benefits of OBJ File Format
There are several benefits of using the OBJ file format for your 3D models. Some of them are:
It enables you to represent complex or irregularly shaped objects by dividing their surface into small, triangular "tiles". This tessellation process makes it easier to manipulate and render the design since you can modify each tile separately from the rest.
It allows you to specify the geometry of 3D objects and their surface properties, including texture mapping and shading. This versatility makes the OBJ file format robust for creating realistic renderings of complex three-dimensional scenes.
It supports high-resolution data compared to similar file formats like STL files. It can store textures and multiple colors in the same object, unlike STL files, which only support one color per object.
It is compatible with many software programs and platforms, making it easy to share your files between different applications. You can also convert your OBJ files into other formats using online tools or software programs.
