How do I test the USDZ on my iPhone?

Send it to yourself via AirDrop or email, or host it on a page: iOS opens it with Quick Look and the AR icon places it in your space through the camera. Works since iOS 12, no apps.

Are animations converted?

The exporter produces the model in a static pose — the GLB's animations don't travel into the USDZ in this conversion. Animated AR on iOS requires a pipeline with Apple's Reality Converter.

What size will the model be in AR?

USD reads units as centimeters while GLB uses meters — the conversion applies the correct factor so a 1 m model still measures 1 m in your living room. If it's still out of scale, check the original GLB's units.

Convert GLB to USDZ

Drop your GLB files and download them as USDZ: free, in batch, and they never leave your device.

GLB → USDZ: what you should know

GLB to USDZ is the bridge into Apple's ecosystem: your web-ready model converted to the format iPhone and iPad open natively with Quick Look — one tap and the piece appears in the user's real space via augmented reality, nothing to install.

The conversion runs 100% in your browser using Three.js's USDZ exporter: the GLB's geometry, PBR materials and textures are repacked into the USD container. Nothing is uploaded to any server.

The complete cross-platform AR combo looks like this: GLB for Android and the web (model-viewer with Scene Viewer) + this USDZ for iOS. With both files, the 'view in your space' button works for everyone.
