Convert PLY to STL online

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

What is kept when converting PLY to STL

Geometry: Kept
Materials: Lost
Textures: Not in PLY
Animation: Not in PLY
Scene hierarchy: Not in PLY

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.

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.

How it works

01
Drop the .ply file (with its textures or .bin/.mtl files, if any).
02
Check the model in the 3D preview; STL is already selected.
03
Click “Convert” and the .stl file downloads.

Questions

Is the PLY to STL converter free?+

Yes, without limits, sign-up or watermark.

Is my PLY file uploaded?+

No. The PLY file is read and converted in your browser; nothing is sent to a server.

Why are textures missing after converting PLY?+

Textures stored as separate files must be selected together with the model. STL keeps them only if the format supports textures.
