How to convert obj to usdz
Drop your OBJ file
Drag the .obj file into the converter above or click to browse. No account and no upload - the file stays on your device.
Conversion runs in your browser
The model is parsed and rewritten locally, in seconds for typical files. Geometry is carried over 1:1 - no remeshing, no quality loss.
Download the USDZ
The .usdz download starts from the same spot. Convert as many files as you like - there is no limit or watermark.
OBJ and USDZ, explained
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.

- Plain-text geometry, with materials in a separate .mtl file

- Blender, Maya, 3ds Max, ZBrush, game engines, 3D scanners
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 survives the obj to usdz conversion
Format conversion is honest work: some data has nowhere to go in the target format. Here is exactly what carries over.
Mesh geometry
All faces carry over exactly, triangulated the standard way.
UV coordinates & normals
UVs survive, so textures applied downstream (or before converting) map correctly.
Materials & textures (.mtl)
OBJ materials live in separate .mtl and image files that are not part of the single file you drop - the USDZ arrives with a neutral material.
Scale interpretation
OBJ is unitless; USDZ/Quick Look assumes meters. A mm-modeled object appears 1000x too large in AR - scale before or after converting.
Multiple objects
Groups carry into the USD scene, keeping the assembled layout.
When should you convert OBJ to USDZ?
Convert to USDZ to put a classic mesh into Apple AR: product mockups, furniture previews, and portfolio pieces viewable in the room straight from Safari.
For appearance-critical AR, route through GLB first: texture the model (by hand or with AI), verify it, then convert GLB to USDZ - the textures come along that way.
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.
