GLB vs USDZ
USDZ is built around Apple AR, such as viewing a product in your room from an iPhone. GLB is the open format that works across the web and most other platforms. Many stores provide both.

How they differ
- Owner: USDZ comes from Apple and Pixar USD. GLB is an open Khronos standard.
- Where it works: USDZ in Apple AR Quick Look. GLB in browsers, Android and most 3D tools.
- Typical use: offer a GLB on the web and a USDZ for iPhone AR.
You do not usually have to choose. If you are building a product viewer, publish GLB for the web and add a USDZ for Apple devices if AR matters to you.
Good to know: MeshShot imports GLB, glTF, OBJ and FBX, and exports GLB, STL and OBJ with Pro. It does not export USDZ.
