PLY to STL Converter

3D scans usually land as PLY. Convert them to STL for slicing and printing — vertices merged, normals fixed.

From scanner to printer

PLY stores scan data (often with per-vertex color that STL can't keep). We extract the triangle geometry, weld duplicate vertices and orient faces consistently. Huge scans are auto-simplified — the metrics line shows the numbers. If your scan has holes, run the result through STL repair.

Frequently asked questions

Is this converter free?
Yes — up to 10 conversions a day and files up to 25 MB, no account needed. Larger files (up to 60 MB) and high-detail STEP output use credits ($9 for 20). Everything runs server-side on real geometry kernels, and failed jobs auto-refund.
What happens to my files?
Files are uploaded only to run your conversion and stored briefly so you can download the result. We don't share them, mine them or train on them. See our privacy policy.
