It enables the seamless display of 3D content in Augmented Reality (AR) and can be displayed directly in iOS applications such as Safari or News without the need for an additional application.
Based on Pixar's Universal Scene Description (USD) format, USDZ is lightweight and optimized for mobile applications.
The Role of USDZ in Augmented Reality
With USDZ, 3D models can be seamlessly integrated into the AR environment without the need for an additional application. This allows users to view products, objects, or designs in their real environment. This is especially useful for e-commerce, architecture, and design.
Integration with iOS and the Apple ecosystem
Apple has deeply integrated the USDZ format into its applications. From Safari to News to Quick Look, USDZ files can be easily viewed in various iOS applications. This provides developers with a standard solution for delivering 3D content to millions of users.
Benefits for developers and businesses
USDZ offers many benefits to developers. Not only does it enable the creation of highly complex 3D objects, but it is also optimized for mobile devices.
Enterprises can use it to create immersive shopping experiences by letting their customers experience products directly in their environment.
Popular Software and Applications

Facts and Features
- Developed in partnership with Pixar: USDZ is based on the Universal Scene Description (USD) format originally developed by Pixar for creating 3D scenes in movies.
- Not a compression format: USDZ is not compressed, which means the files retain their original size and quality, but without the overhead associated with compression.
- 3D capabilities: The format supports various 3D features such as geometry, lighting, cameras, and animation, making it suitable for a wide range of applications.
- Open architecture: USDZ is not limited to Apple products, but is an open format that can theoretically be used on any platform that supports USD.
- Website integration: USDZ files can be easily integrated into websites to display AR objects directly in the browser.
- Ideal for ARKit: USDZ is tightly integrated with Apple's ARKit, an augmented reality application development platform, making it easy to integrate into AR experiences.
- Rendering engines: USDZ can be used in a variety of 3D rendering engines, including Unity and Unreal Engine, making it attractive to developers.
- Multi-platform approach: Although USDZ is particularly rooted in the Apple ecosystem, its base in the USD format means that it can be used in other environments such as desktop computers and VR.
- File conversion: There are several tools that can be used to convert common 3D file formats such as OBJ or FBX to USDZ.
Frequently Asked Questions
Can I view USDZ files on Windows and Android?
USDZ files are primarily supported by Apple devices, but there are tools and software available to view them on Windows or Android. However, seamless integration like iOS and MacOS is not possible.
What software can be used to create USDZ files?
Programs such as Blender, Autodesk Maya, and Apple's Reality Composer support USDZ file creation. There are also plugins and conversion tools that make it easier to export to the USDZ format.
Are there any file size limitations for USDZ?
Although USDZ is optimized for mobile devices, there is no fixed size limit. However, you should keep the file size small to improve loading times and performance.
How is USDZ different from other 3D file formats?
USDZ is specifically optimized for AR applications and does not require compression, making it uniquely suited for mobile and AR applications, unlike formats such as FBX or OBJ.
Would it be possible to include animation in USDZ files?
Yes, USDZ supports animation as well as static 3D models, making it ideal for interactive AR experiences.
