What is an FBX file?
An FBX file is a 3D model saved in the Autodesk Filmbox format. It can be used and shared across a variety of digital modeling and content creation programs, including the Autodesk suite of applications. Game developers and animators often use FBX files.
While the FBX format is proprietary, many non-Autodesk modeling and animation applications can open FBX files. This allows creators to share 3D models in the FBX format, which is efficient because it stores models as binary data.
How to convert 3D models to the FBX format
Model creators can convert models to the FBX format using Blender (multiplatform) or Autodesk FBX Converter (Windows and Mac, but unsupported as of 2013). For example, Autodesk FBX Converter can convert .OBJ, .DXF, .3DS, and .DAE (COLLADA) files to the FBX format.
NOTE: Kaydara originally developed the FBX format for use in Kaydara MotionBuilder. Autodesk acquired Kaydara in 2006.
How to open an FBX file
You can import FBX files into many different 3D modeling and animation applications, including Autodesk Maya (multiplatform) and Blender (multiplatform). However, if you just want to quickly view the model your FBX file contains, the quickest way to do so is by opening it with Autodesk FBX Review (Windows, Mac, iOS) or Autodesk Viewer (Web).
