Apple AR zip in. Desktop mesh out.
Use this when the destination is an OBJ importer. PBR from the USDZ does not survive. Faces do. Prefer USDZ to GLB if you still need the look on the web.
Source USDZ, target OBJ, drop, download. MTL is not written.
1
Source is USDZ. The File API reads it in this tab. Nothing is posted. Keep it under 80 MB.
2
Faces are written as OBJ. Maps stay behind.
3
Open in the DCC. Keep the USDZ for Quick Look.
This page is only USDZ → OBJ. Other pairs have their own keep and lose notes so they do not repeat this conversion.
| On this conversion | What happens |
|---|---|
| Keeps | Triangle geometry. |
| Drops | PBR, textures, and the Quick Look zip. |
| Next step | Import OBJ in the DCC. For print, use USDZ to STL. |
| Attribute | Result on the reference scene |
|---|---|

| UV coordinates | Kept |
| Vertex colour | Lost |
| Material names | Kept |
| Vertices on the reference scene | 72 of 48 |

USDZ as the source: Geometry only. Color and clips are dropped. Measured 2026-09-13 by running this converter’s own loaders and exporters headlessly. How every format was measured.
USDZ is parsed with the File API. OBJ is written in memory. PBR, textures, and the Quick Look zip. That is a format rule, not an upload. Files over 80 MB are refused because RAM is the limit.
Use this when the destination is an OBJ importer. PBR from the USDZ does not survive. Faces do. Prefer USDZ to GLB if you still need the look on the web.
Source USDZ, target OBJ, drop, download. MTL is not written. No Blender and no account.
When the next app has an OBJ importer and no USDZ or GLB importer. It is not a way to keep the AR look.
No. This writer outputs mesh geometry. Keep the USDZ or convert USDZ to GLB for lookdev.
No. USDZ is parsed here and OBJ is written in memory. There is no convert API.
Yes. Open the USDZ viewer if you only need to orbit. Convert when the next tool actually wants OBJ.
Import OBJ in the DCC. For print, use USDZ to STL.
