What is a .USDZ file?
USDZ is Apple’s augmented-reality 3D format, opened straight from Safari and iMessage. Based on Pixar’s USD.
- Did you know
- Apple introduced USDZ in 2018 as the format for AR Quick Look on iPhone and iPad.
- A USDZ package keeps every contained file aligned to 64-byte boundaries so the assets can be read straight from disk by memory mapping, without unpacking.
- A USDZ is an uncompressed ZIP of Pixar's USD scene plus its textures, so an iPhone can stream a 3D model into the real world straight from a web page.
- Under the hood a .USDZ file is really a ZIP archive - rename it to .zip and you can browse the files inside.
- What Analyser reads
- Identify 3D and 3D-printing files: FBX, USD/USDZ, Blender (BLEND), Raise3D ideaMaker projects and print profiles (IDEA) and Zortrax Z-SUITE compiled prints (ZCODE). A Blender scene saved with preview images gives up the thumbnail it stored, so you can see what the scene looked like without opening Blender. OBJ, PLY, OFF, 3MF, AMF and glTF/GLB get a full 3D viewer - see the 3D model section.
- Depth of analysis
- .USDZ is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .USDZ file
- Drag a .USDZ file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
