USDZ and OBJ, explained

What is USDZ?

USDZ is Apple's AR format: Pixar's Universal Scene Description packed into a single file that iPhones and iPads open natively in AR Quick Look - no app required. E-commerce product previews on Apple devices run on USDZ.

USDZ shines on Apple platforms and almost nowhere else, so the common workflows are converting a GLB into USDZ to ship an AR preview, or unpacking a USDZ back into GLB/OBJ to edit it in standard tools.

What is OBJ?

OBJ is the plain-text workhorse of 3D interchange. It stores vertices, faces, UV coordinates, and normals in a human-readable file, with materials referenced from a companion .mtl file. Practically every 3D application of the last 30 years can read it.

Because OBJ splits materials and textures into separate files, a bare .obj carries geometry and UVs but shows up untextured unless the .mtl and texture images travel with it. It has no units, no rigging, and no animation - which keeps it simple and universally compatible.

What survives the usdz to obj conversion

Format conversion is honest work: some data has nowhere to go in the target format. Here is exactly what carries over.

Mesh geometry

Every mesh carries over exactly, with USD scene transforms baked in.

UV coordinates & normals

UVs survive into the OBJ, so retexturing downstream maps correctly.

Materials & textures

The output is the mesh-only .obj - USDZ's embedded textures would need separate .mtl and image files. UVs are preserved for reapplication.

Scale interpretation

USD meters copy 1:1 into unitless OBJ - tools that assume other units may need an import scale adjustment.

When should you convert USDZ to OBJ?

Convert to OBJ to edit what only exists as USDZ: e-commerce AR assets, iPhone scans, and Quick Look downloads become workable in Blender, ZBrush, CAD tools, and renderers.

Keep the USDZ for Apple AR delivery - it is the format iPhones open natively. Edit via OBJ, then convert back (OBJ to USDZ) for the AR copy.

And if what you actually need is a new model rather than a new file format: 3D AI Studio's main tool can generate 3D models from photos with AI - with exports to every format on this page.
