What is USDZ in 3D modeling file formats?

USDZ is a compact, self-contained 3D file format co-created by Apple and Pixar for sharing and displaying 3D content across devices. It packages Universal Scene Description (USD) data into a single zip file, removing extra dependencies—ideal for AR experiences, 3D previews, and cross-platform distribution. It’s widely used in Apple’s ecosystem (iOS, macOS) like ARKit, Safari, or Messages, letting users view 3D models on iPhones/iPads/Macs without installing software. To create USDZ files, use Blender (with USD plugins) or convert OBJ/FBX files via Apple’s Reality Converter. In short, USDZ simplifies 3D content sharing, especially for Apple users and AR applications.
