What is a .FBX file?
FBX is a widely used 3D interchange format for models, animation and scenes. Owned by Autodesk and read by most 3D and game tools.
- Did you know
- FBX began at Kaydara for the MotionBuilder app and is now Autodesk’s main 3D exchange format.
- FBX started as Kaydara’s replacement for the motion-capture format used by Filmbox, the app later renamed MotionBuilder.
- Autodesk gained FBX through its 2006 purchase of Alias, which had itself acquired Kaydara two years earlier.
- What Analyser reads
- Identify 3D and 3D-printing files: FBX, glTF/GLB, USD/USDZ, and Blender (BLEND). OBJ, PLY, OFF, 3MF and AMF get a full 3D viewer - see the 3D model section.
- Depth of analysis
- .FBX is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .FBX file
- Drag a .FBX file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
