If you want a 3D model to show up in someone’s real living room through an iPhone, you almost always end up with USDZ. Apple wired the format so tightly into Quick Look that any iPhone user can pull a USDZ model into their environment with one tap, straight from Safari, Mail or Messages. No app install, no account, no detour.
Most 3D pipelines start with GLB for the web, then need a USDZ derivative for iOS AR. The fastest way to make one without leaving the browser is our free GLB to USDZ converter. For WordPress sites running Elementor, PausAR Viewer then takes both files (USDZ for iOS, GLB for the rest) and serves the right one to each device automatically. No coding, no separate setup for iOS and Android.

Yes. USDZ is built on Pixar's open Universal Scene Description (USD). No license fee for creating or serving the files.
