Free Online USD to OBJ Converter

You can use our USD to OBJ 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 USD to OBJ 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 USD file, once uploaded to our server, will be deleted 15 minutes after upload, so please download your converted USD file before this time.

Our 3D model USD to OBJ tool will load your USD 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.

First, click the "Upload..." button and select your USD file to upload. Your USD file will be uploaded to our servers. When the USD to OBJ conversion has completed, you can download your OBJ file right away.

How long does it take to convert my USD to OBJ?

We aim to process all USD to OBJ conversions as quickly as possible; this usually takes around 5 seconds; however, this can be longer for certain files, so please be patient.

How accurate is the USD to OBJ 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 USD to OBJ work?

In order to successfully convert an USD formatted file to the OBJ format, our converter tools will perform several initial checks to ensure the file provided is indeed an USD 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 USD files to the exact specification.

Take your USD file

An USD file is a binary data file containing 3D data that makes up the 3D model, including vertices, faces, texture coordinates, and more. To guarantee efficient conversions, our tool will check all data that is contained within the USD file and remove any information that is duplicated. This not only ensures the conversion completes more quickly, but also the generated OBJ file size is smaller.

Convert the data from USD to OBJ

Now that the data from the USD 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 OBJ file format. Part of this process ensures checking the capabilities of the OBJ format and removing any data that cannot be represented.

Save to the OBJ format

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

File format information for USD and OBJ

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.

The OBJ file format is a 3D graphics file format used to define complex 3D models, including geometry, materials, and textures. OBJ files are text files, making them human-readable and easy to modify by hand. The downside to this ease of readability is that the files can become rather large when dealing with large or complex 3D models.

As mentioned, the OBJ format stores not only 3D model geometry but also materials and textures. These materials are usually defined in a separate file with the MTL file extension and specify geometry rendering details such as diffuse and specular colour, transparency, and much more.

The OBJ material file can also reference external texture files. These are usually JPEG or PNG files; however, these can be older formats, such as TGA. Where materials are used, the OBJ file will also contain material names preceding the geometry faces they should be applied to. If textures are referenced, the geometry will also contain texture coordinates (UV) for each vertex.

When converting your USD to OBJ, our tool will attempt to accurately convert any colour or material information.

Information for converting from USD to OBJ

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