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). 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.
