Beginners upload USDZ 3D models by choosing an AR/3D-compatible platform, preparing the file, and following the platform’s steps.
First, pick a platform like Sketchfab (for sharing) or Apple’s AR Quick Look (for AR testing)—USDZ works best with AR tools. Next, prep your file: Keep it under the platform’s size limit (usually 50MB–100MB) and ensure textures are embedded (USDZ stores them internally, so no separate files needed). Then, go to the platform’s “Upload” page, select your USDZ file, add basics (title, category), and publish.
For new users, start with AR Quick Look—upload to iCloud Drive, open on an iPhone/iPad, and tap “Share” to send or add to a simple website. For public sharing, Sketchfab’s free plan is user-friendly and lets others preview your USDZ in 3D/AR.
