OBJ to USDZ converter
Updated September 2026
What is an OBJ to USDZ converter?
Desktop mesh in. Apple AR zip out.
Use this when you have an OBJ and the destination is Quick Look. MTL maps are not applied. You get a USDZ with a default material around the OBJ hull.
How to convert OBJ to USDZ
Source OBJ, target USDZ, drop the .obj only, download .usdz.
1
Drop a OBJ file
Source is OBJ. The File API reads it in this tab. Nothing is posted. Keep it under 80 MB.
2
Write USDZ
A USDZ is written around the OBJ mesh with a default material.
3
Take the file to the next tool
AirDrop the .usdz. Keep the OBJ for the DCC.
OBJ versus USDZ on this route
This page is only OBJ → USDZ. Other pairs have their own keep and lose notes so they do not repeat this conversion.
| On this conversion | What happens |
|---|---|
| Keeps | Triangle geometry inside USDZ. |
| Drops | MTL and texture lookdev. Default material only. |
| Next step | Open on iOS. For a web pack, use OBJ to GLB instead. |

OBJ as the source: Default material on export. Source has no PBR to keep. Measured 2026-09-13 by running this converter’s own loaders and exporters headlessly. How every format was measured.
OBJ to USDZ stays in this tab
OBJ is parsed with the File API. USDZ is written in memory. MTL and texture lookdev. Default material only. That is a format rule, not an upload. Files over 80 MB are refused because RAM is the limit.
