STL to XYZ Converter
Drop a .stl file below and get a .xyz back. The conversion happens inside this page using WebAssembly, so nothing is uploaded to a server and there is no queue to wait in.
- Private by designFiles stay on your device.

How to convert STL to XYZ
- 1Add your STL fileDrop the .stl file into the box, or pick it from disk. Multiple files are converted one after another.
- 2Pick XYZ as the outputXYZ is already selected on this page. Adjust scale, up axis or triangle budget if the target application is picky.
- 3Download the resultThe .xyz file is written locally and appears as a download button next to your file.
About STL
STL stores a model as a flat list of triangles with no units, colors or scene structure. Its simplicity is exactly why every slicer and every 3D printer on the market reads it, and why it is still the default export target for mechanical parts.

About XYZ
An XYZ file is one point per line: three coordinates, sometimes followed by RGB values. It has no faces and no header, which makes it trivially easy to generate from any script or measurement device.
- Point clouds carry no faces. Exporting a mesh to XYZ writes its vertices and discards the triangles.

- MeshLab
- AutoCAD

Questions
Is this STL to XYZ converter free?
Yes. There is no account, no daily quota and no watermark. The tool is a static web page and the work is done by your own CPU, so there are no server costs to pass on.
Are my files uploaded anywhere?
No. MeshFormat loads a WebAssembly build of the geometry kernels into your browser and reads the file locally. You can open the network tab and confirm that nothing leaves the page, or disconnect after the page has loaded and keep converting.
How large can a STL file be?
The practical limit is your available memory rather than an arbitrary cap. Models up to a few hundred megabytes work on a normal laptop; very dense scans convert faster if you lower the triangle budget in the options.
Anything to know about XYZ output?
Point clouds carry no faces. Exporting a mesh to XYZ writes its vertices and discards the triangles.
Which programs open XYZ files?
CloudCompare, MeshLab, AutoCAD, QGIS and most other tools that work with 3D meshes read .xyz directly.
