What is a FBX file?
FBX is Autodesk's interchange format for 3D scenes, meshes, materials, rigs and animation. Open supported ASCII or binary FBX geometry locally, then orbit, pan and zoom without uploading the model. The .FBX extension identifies a Filmbox 3D model file, which is served with the application/octet-stream media type. You can open it here instantly — drop the file into the box above and it renders in your browser. Nothing is uploaded.
FBX is common in game development, animation, visualisation and transfers between Maya, 3ds Max, Blender and other DCC tools. The viewer reads the selected file in browser memory and builds an interactive Three.js scene, which is useful for a fast geometry check before opening a full authoring application.
Besides this free online viewer, you can open FBX 3D model files in desktop apps such as Autodesk Maya, 3ds Max, Blender — but here all you need is a web browser.

- Review supported materials and scene hierarchy before hand-off
- Preview a client or supplier model on a device without CAD software
What this browser preview can and cannot show
FBX is a broad proprietary ecosystem. Complex constraints, controllers, plug-in data, advanced shaders, animation features and textures stored as separate files may not reproduce exactly. Use the original authoring tool for final visual approval.
Tips for a reliable preview
- Keep external texture files beside the model when working in a desktop application
- For dependable web delivery, consider exporting a GLB copy
- Large production scenes load faster after removing hidden or unused objects

Frequently asked questions
What is a .FBX file?
A .FBX file is a Filmbox 3D model, identified by the application/octet-stream media type. You can open and read it instantly in the viewer above without installing anything.
What programs open FBX files?
On the desktop, FBX files typically open in Autodesk Maya, 3ds Max, Blender. Online, this page opens them in any modern browser — nothing to download.
How do I convert FBX to an image?
