| Extension | OBJ |

| Mime Type | text/plain |
| Format | Text |
An OBJ file is a text-based file format used for the storage of 3D model data. The format was developed in the 1980s by Wavefront Technologies as a means to store the geometric mesh data associated with a 3D model. It has garnered widespread support in the following years, and you will find options to load from and save to the OBJ format in most modern 3D modeling applications.
As OBJ files are essentially text files, they can grow quite large when working with large and detailed 3D models.
Mesh Geometry
Within a 3D OBJ file are lists of vertices, mesh faces, face normals, texture coordinates, and more. The vertices, normals, and texture coordinates are stored in a continuous list and are indexed referenced within a separate list of mesh faces, ensuring optimal use of space within the file. A mesh face may contain three or more points, each of which can use a unique vector normal and texture coordinate.
OBJ Converter Capabilities
As materials containing texture and color information are both supported by the OBJ format, our tool will do its best to include these materials, including any texture files, in the converted file.

The FBX format, which is short for Filmbox, is a 3D modeling format developed by Autodesk with the aim of making it an open and easy-to-use way to distribute 3D models. The format started out in the mid-1990s and quickly gained traction, with its development continuing to this day.
Along with compatibility with Autodesk's Maya and 3Ds Max applications, FBX files have gained support with other 3D model editors, including Blender.
Mesh Geometry
An FBX file is composed of 3D mesh data, including vertices, faces, normals, textures, and animations, in a text and binary format to produce a portable file that is both easy to develop and compact and efficient as a medium for the distribution of models and full 3D scenes.
FBX Converter Capabilities
As materials containing color information is supported by the OBJ and FBX formats, our tool will do its best to include this in the converted FBX file.
