Free online FBX to USD converter

Source format: FBX

FBX (Filmbox) is a widely used 3D interchange format developed by Autodesk. It is common in game development, animation, VFX, and 3D content creation pipelines because it can store meshes, materials, skeletons, skin weights, animations, cameras, and lights. Artists often use FBX to move assets between tools such as Maya, 3ds Max, Blender, Unity, and Unreal Engine.

Target format: USD

USD (Universal Scene Description) is a modern 3D scene format created by Pixar and now widely adopted across film, animation, and real-time workflows. It is designed for large scenes, non-destructive layering, and efficient collaboration between tools. USD can represent complex scene hierarchies, variants, references, animation, and asset composition, making it especially useful for production pipelines and interchange between DCC applications.

How to perform the conversion

The most reliable way to convert FBX to USD is with a desktop 3D application that supports both formats, such as Blender or Autodesk Maya. If you only need a quick conversion, you can also convert the file on 101convert.com for free without installing any software.

Using Blender

1. Open Blender.
2. Import the FBX file with File → Import → FBX (.fbx).
3. Check the imported model, materials, and animation in the scene.
4. Export to USD with File → Export → Universal Scene Description (.usd/.usda/.usdc).
5. Choose the desired USD flavor: .usd for binary, .usda for ASCII, or .usdc for binary compressed-style output, then save the file.

Using Autodesk Maya

1. Open the FBX file in Maya, or import it with File → Import.
2. Verify that the scene, skeletons, and animation imported correctly.
3. Export using File → Export Selection or File → Export All.
4. Select a USD export option if the USD plug-in is enabled, then save as .usd, .usda, or .usdc.

Using the 101convert.com online converter

1. Open the FBX to USD conversion page on 101convert.com.
2. Upload your .fbx file.
3. Start the conversion and wait for the USD file to be generated.
4. Download the resulting .usd, .usda, or .usdc file.

Notes on quality, compatibility, and limitations

FBX to USD conversion is not always one-to-one. Geometry usually transfers well, but materials, shaders, embedded textures, animation curves, and rigging can require cleanup depending on the source application and exporter. USD is excellent for scene organization, but it may not preserve every FBX-specific feature exactly as authored.

For best results, keep the source asset simple before conversion: apply transforms, check unit scale, and make sure textures are accessible. If the FBX contains animation, verify frame rate and skeleton hierarchy after export. Also note that some tools support only certain USD variants, so choose .usd, .usda, or .usdc based on your pipeline needs and compatibility requirements.
