Output format

GLB uses metres; OBJ, PLY and STL export in millimetres. Your original file is unchanged.

Open a model first.

Mesh conversion does not preserve editable CAD features. Colours / materials may vary by format. Check scale and printability before use.

Private by design

Selected models are processed in this browser tab, not sent to Quality3Ds or another service. There is no model storage or automatic submission. Clear the model or close this tab when you’re finished.

Working with CAD?

Export your part or assembly as STEP, STL or standard 3MF first. Native CAD files and mesh-to-STEP conversion are not supported. For multi-part 3MF slicer projects, export a standard single-model 3MF or STEP/STL copy. General ZIP archives and Draco compression are not supported.
