U3D file format information

Full NameUniversal 3D
Type3D Model
Mime Typemodel/u3d

A U3D file is a digital 3D model file format used to represent three-dimensional objects and scenes. The acronym "U3D" stands for Universal 3D, indicating its aim to be a versatile format compatible with various applications and platforms. U3D files store geometric information about the object's shape, such as vertices, edges, and faces, as well as texture coordinates and material properties. Additionally, U3D files can contain animation data, allowing the model to be animated and brought to life in compatible software. Due to its compact size and efficient representation, U3D is often employed for 3D graphics in interactive applications, such as real-time 3D visualization, video games, and augmented reality experiences.

U3D files are commonly used in conjunction with PDF documents, serving as embedded 3D content within a PDF file. This integration allows for interactive 3D elements in PDFs, enhancing presentations, technical documentation, and educational materials. Users can rotate, pan, and zoom into the 3D model directly within the PDF viewer, providing a more engaging and immersive experience. Moreover, U3D's compatibility with PDF ensures that the 3D content can be shared, viewed, and interacted with across different devices and platforms without the need for specialized 3D modeling software.

Developed by the 3D Industry Forum (3DIF) and later adopted as an open standard by Ecma International, U3D files continue to be supported by various 3D software applications and libraries. Its versatility, portability, and ability to enrich 3D content in PDF documents have contributed to its widespread use in diverse fields, including architecture, engineering, medicine, and entertainment. However, as with any file format, it is essential to ensure compatibility with the intended software and check for updates to maintain optimal performance and compatibility with evolving 3D technologies.

U3D Converter Capabilities

Currently our U3D converter can only convert from U3D files, our developers are working to allow converting to U3D files in future versions of our tools. Our U3D 3D Model/Mesh tool does not support any color material data contained within U3D files so the converted file will not contain any color information.

Frequently Asked Questions

How accurate is the 3D file conversion?

Our U3D conversion tool can convert most 3D geometry including mesh vertices and faces with no loss of detail. Any color materials contained within the 3D model file will be converted where possible.

Are textures supported in the U3D conversion?

No, due to the different methods of assigning textures to a 3D model textures are not currently supported. If your U3D model contains textures or references to external texture files, these will be ignored.

Is it free to use the U3D conversion tools?

Yes! Our U3D conversion tools are 100% free to use.

Are there any U3D conversion usage limits?

No, you can convert as many files as you wish. We do not impose any conversion limits on our U3D conversion tools.

How long does it take to convert my U3D?

We aim to process all U3D conversions as quickly as possible, this usually takes around 5 seconds however this can be longer for certain files and significantly longer for some larger file formats, so please be patient.

What does the U3D conversion process involve?

Once your U3D file has been uploaded and we know the file format you wish to convert it to our bespoke conversion software will convert your U3D and make it available for you to download with a unique download Url.

Is it safe to convert my U3D on

Yes, of course it is! Your U3D, once converted is deleted 1 hour after upload and the download link will expire after this time.

Can I convert my U3D on Linux, Android, iOS or Mac OS?

Yes! Our U3D conversion tools will run on any system with a modern web browser.

Is there any support for me when using the U3D tool?

If you are having difficulty converting your U3D you can contact us and we will try to help where possible.
