Key Benefits of Converting from FBX
FBX (Filmbox) is Autodesk's proprietary interchange format, the de facto standard for transferring animated 3D assets between applications like Maya, 3ds Max, and game engines like Unity and Unreal Engine. FBX supports skeletal animation, blend shapes, cameras, lights, and complex multi-material meshes, making it the backbone of most game and film production pipelines.
Why Convert FBX Files?
Despite its ubiquity, FBX is proprietary and its binary format is not openly documented. Converting FBX to open formats like GLTF or COLLADA (DAE) improves long-term accessibility and interoperability. For web delivery, converting to GLB produces compact, self-contained files ideal for WebGL viewers. For 3D printing, export to STL or 3MF.
How LetsConvert Handles FBX to X Conversion
LetsConvert uses the industry-leading Assimp (Asset Import Library) to convert FBX (Autodesk FBX) files to X (DirectX X) format. Assimp supports over 40 3D import formats and 22 export formats, making it the most comprehensive open-source 3D conversion library available.
FBX to X Conversion Process
Upload your FBX file and LetsConvert will parse the complete 3D scene including meshes, materials, and hierarchies, then export the result in X format. The conversion preserves geometry, normals, UV coordinates, and material information where both formats support the same data. Your converted X file is ready for download immediately after processing.
Why Convert to X (DirectX)
LetsConvert's FBX to X converter creates a DirectX X file — the legacy Microsoft 3D format still used in classic game development, DirectX education, and legacy Windows applications.
X Output Advantages
The resulting X file is compatible with DirectX 8/9-era game engines, educational rendering samples, and legacy applications built on the DirectX SDK. Use this format when maintaining or extending classic DirectX-based software.

Is the FBX to X conversion free?
Yes. LetsConvert's FBX to X converter is completely free to use with no registration required for standard conversions.
Will my FBX file's geometry be preserved during conversion to X?
Yes. LetsConvert preserves mesh geometry, normals, and UV coordinates during conversion. Material and animation data are preserved where both the FBX and X formats support the same features.
What is FBX (Autodesk FBX)?
FBX is a 3D file format used for storing three-dimensional model data. See the section above for details about the FBX format.
What is X (DirectX X)?
X is a 3D output format. Converting your FBX to X allows you to use the model in applications and workflows that require the X format.
How long does FBX to X conversion take?
Most FBX to X conversions complete in seconds. Larger files with many polygons or embedded textures may take slightly longer.
