Apple AR zip in. PLY mesh out.
Research apps sometimes want PLY even when you started in USDZ. This route dumps geometry to binary PLY. It is the wrong route for a slicer (use USDZ to STL) and the wrong route for web (use USDZ to GLB).
Source USDZ, target PLY, drop, download binary PLY.
1
Source is USDZ. The File API reads it in this tab. Nothing is posted. Keep it under 80 MB.
2
Binary PLY from the USDZ mesh.
3
Open in the PLY tool. Keep the USDZ if you still need Quick Look.
This page is only USDZ → PLY. Other pairs have their own keep and lose notes so they do not repeat this conversion.
| On this conversion | What happens |
|---|---|
| Keeps | Faces for PLY-aware software. |
| Drops | The USDZ material pack and Quick Look zip. |
| Next step | MeshLab or a scan pipeline. Print should have been USDZ to STL. |
| Attribute | Result on the reference scene |
|---|---|
| Separate objects | Merged into 1 |
| UV coordinates | Kept |
| Vertex colour | Kept |
| Material names | Lost |
| Vertices on the reference scene | 48 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. PLY is written in memory. The USDZ material pack and Quick Look zip. That is a format rule, not an upload. Files over 80 MB are refused because RAM is the limit.
Research apps sometimes want PLY even when you started in USDZ. This route dumps geometry to binary PLY. It is the wrong route for a slicer (use USDZ to STL) and the wrong route for web (use USDZ to GLB).
Source USDZ, target PLY, drop, download binary PLY. No Blender and no account.
Pipelines that standardized on PLY. Everyone else should pack to GLB or print via STL.
No. This is a mesh dump, not a USDZ pack.
No. USDZ is parsed here and PLY 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 PLY.
MeshLab or a scan pipeline. Print should have been USDZ to STL.
