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 its FilmBox software, which is where the name comes from, 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, USD/USDZ, Blender (BLEND), Raise3D ideaMaker projects and print profiles (IDEA) and Zortrax Z-SUITE compiled prints (ZCODE). A Blender scene saved with preview images gives up the thumbnail it stored, so you can see what the scene looked like without opening Blender. OBJ, PLY, OFF, 3MF, AMF and glTF/GLB 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.
