PLY vs STL

PLY: PLY is a mesh format common for 3D scans, often with a colour per vertex.

STL: STL describes a shape as triangles only: no units, no colours, no curves. It's what 3D printers, slicers and scanners use.

FAQ

PLY to STL questions

Short answers. If yours isn’t here, ask us — a person replies.

Is the PLY to STL converter free?

Yes, with no sign-up and no limit on the number of files. A free account is only needed if you want to send the model to someone for feedback.

Is my file uploaded?

Most files are read and converted right in your browser and never leave your computer. Very large CAD and mesh files are converted on our server instead, then deleted straight after the converted model is sent back to your browser.

What's the biggest PLY I can convert?

Up to 1 GB. Big files take longer, and very large CAD files go through our server, as above.

Does it keep colours?

No. STL has no colours or materials, only the shape. Convert to GLB to keep them.

Converting it to send to a client or supplier?

Send them a link instead. They open the model in any browser, with no account and no CAD program, and click the spot they want changed.
