STL to PLY
Turn STL 3D model files into PLY 3D model files on your own Mac, Windows or Linux computer. Asteria is free, works offline, and never uploads your files.
How to do it
- Download Asteria and open it. It's free and needs no account.
- Drop your STL files onto its window, or press ⌘O (Ctrl O on Windows) to choose them. Drop as many as you like.
- Type stl to plyand pick Convert to PLY. Write the mesh as binary PLY.
- Press ⌘↵ (Ctrl ↵ on Windows) to save. The PLY files appear next to the originals, which stay exactly as they were.
What it needs
Nothing. This conversion is built into Asteria, so it works the moment the app is open, even offline.
How it was tested
A real STL file was converted on Linux, and the PLY that came out was opened and checked with Assimp to make sure it is what it says it is.
