Convert STL to PLY online
Drop a .stl file to turn it into PLY. You see the model in 3D before converting, and the file never leaves your device.

About STL
Stereolithography
STL describes only the surface of a model as triangles — no colors, materials or textures. It is the default format for 3D printing and slicers.
About PLY
Polygon File Format (Stanford)
PLY (Stanford) stores meshes or point clouds, often with per-vertex colors. It is common for 3D scans and photogrammetry.
How it works
- 01
Drop the .stl file (with its textures or .bin/.mtl files, if any).
- 02
Check the model in the 3D preview; PLY is already selected.
- 03
Click “Convert” and the .ply file downloads.
Questions
Is the STL to PLY converter free?+
Yes, without limits, sign-up or watermark.
Is my STL file uploaded?+
No. The STL file is read and converted in your browser; nothing is sent to a server.
Why are textures missing after converting STL?+
Textures stored as separate files must be selected together with the model. PLY keeps them only if the format supports textures.
