Free Online FBX to USD Converter

You can use our FBX to USD conversion tool to quickly and easily convert your 3D model files for free. You may upload up to 20 files at one time, and our batch FBX to USD converter will process each 3D model and present you with a download link for each file once completed.

Select File(s)

Or drag and drop your files here to upload.
A maximum of 20 files can be uploaded at once.

Please note: Your FBX file, once uploaded to our server, will be deleted 15 minutes after upload, so please download your converted FBX file before this time.

Our 3D model FBX to USD tool will load your FBX file and, where supported, attempt to extract all the relevant 3D features, such as geometry, textures, and animations. To access the 3D conversion configuration options, click the button when you have selected your files. The current options support the ability to voxelize your 3D model and more.

How accurate is the FBX to USD conversion?

We aim to provide the best conversion experience. Our tools are under constant review and development, with new features being added every week.

How does converting FBX to USD work?

In order to successfully convert an FBX formatted file to the USD format, our converter tools will perform several initial checks to ensure the file provided is indeed an FBX file. There are many files out there where the file type extension does not match the data contained within the file. Along with these file type checks, our tools will do additional checks to ensure the file is correctly formatted to match the provided file type. There are many tools out there that do not always create FBX files to the exact specification.

Take your FBX file

The FBX file format can be either a text-based or binary format, meaning if its content is plain text, it is human-readable; otherwise, if it is binary, then it can only be edited with specialist FBX editing software. The data within the file, regardless of whether it is text or binary, contains the core elements that make up the 3D model, including vertices, faces and more. To guarantee efficient conversions, our tool will check all data that is contained within the FBX file and remove any information that is duplicated. This not only ensures the conversion completes more quickly, but also that the generated USD is smaller.

As the USD file format does not support material textures, our tool when processing the FBX file will ignore any texture image files that may be present. It will also ignore any texture coordinate information present in the 3D model data.

Convert the data from FBX to USD

Now that the data from the FBX file has been processed, our tool can apply any conversion specified options, such as enabling Voxel mode, and with these applied, prepare the data to be converted to the final USD file format. Part of this process ensures checking the capabilities of the USD format and removing any data that cannot be represented.

Save to the USD format

At this point, the FBX to USD conversion tool will have the 3D model in a state that is ready to be transferred to the USD format. Our tool creates the USD file, ensuring all the model data is present and is formatted to match the USD file specification to ensure the file opens in compatible USD file editors.

FBX files are an open 3D file format developed by Autodesk for use with their Maya and 3Ds Max applications. An FBX file may contain any number of 3D objects, their associated geometry, materials, textures, animations, and more, all within a single convenient package.

The content of an FBX file is a mix of binary and ASCII text, producing a format that is both human-readable and compact. Due to their compact size, ease of use, and widespread support, FBX files are a popular choice for creating 3D animations and are also a staple in the videogame development scene.

The development of the FBX format continues to this day, with new features being included in each release. Along with being used within Autodesk's own editing solutions, FBX files can also be opened and edited in other popular 3D modelling applications, such as Blender.

USD files are a 3D model format designed specifically for the exchange of 3D data between different systems within a standard and easy-to-implement format.

Within a USD file are the various data elements that make up the 3D model, including vertices, faces, normals, and texture coordinates. Along with this basic geometry, other important information is stored, such as camera and other environmental properties.

Support for exporting 3D content to the USD format can be found in certain 3D modelling applications, such as Blender, Maya, and Houdini.

Information for converting from FBX to USD

Your FBX file will be converted to a USD file using our unified 3D model and mesh conversion tool. Our FBX 3D tool performs accurate conversions of 3D elements such as vertices, faces, normals, and relevant material information. As both FBX and USD support colour material information, our tool will also attempt to convert the colour information.
