PLY to STL
- Kept. shape.
- Dropped. colours.
- Size. Written in the unit you pick, millimetres for printing.
The two types
- PLY. PLY stores points or triangles with a colour per vertex. 3D scanners and photogrammetry tools write it. Opened by MeshLab, CloudCompare, Blender and most scanning software.
- STL. STL describes a surface as triangles and nothing else: no colour, no units. Slicers read its numbers as millimetres. Opened by Cura, PrusaSlicer, Bambu Studio, Blender, MeshLab and Fusion 360.
Questions
How do I convert PLY to STL?
Drop the PLY file on this page, check the size under What’s inside, and press Download STL. It runs in your browser, so there is no upload and no wait.
What does PLY to STL keep?
STL keeps the shape. It has no place for colours, so that is dropped.
What size will the STL be?
STL has no units, and slicers read its numbers as millimetres. The page writes millimetres, so a 40 mm part from PLY arrives 40 mm long. If the size looks off, change File is in and Write as under What’s inside.
Will the STL print?
What’s inside says whether the surface is closed, which slicers need. If it is open, repair it in your slicer, Meshmixer or Blender first.
Why does a PLY from my scanner say it has no faces?
Some scanners save a cloud of points with no surface between them. Without faces there is nothing to convert. Build a mesh from the points in MeshLab or CloudCompare first.
Is my file uploaded?
No. The file is opened and converted in your browser, and it stays on your device.
Is it free?
Yes. There is no account, no watermark and no limit on files.
