Convert STL to PLY
Drop your STL files and download them as PLY — free, in batch, and they never leave your device.
STL → PLY: what you should know
STL is the standard format of 3D printing: a triangle mesh with no explicit units, no color and no materials. It's used mostly in slicers (Cura, PrusaSlicer, Bambu Studio), FDM and resin 3D printing, CAD, and it stores geometry only (triangles and normals). PLY, on the other hand, is a mesh or point-cloud format that can store per-vertex color — typical of 3D scanners — the format expected by 3D scanning, photogrammetry, mesh processing (MeshLab, CloudCompare).
This tool converts your STL files to PLY right in the browser: no queue, no artificial size limit and, above all, your file is never uploaded to any server. Geometry is preserved with the exact coordinates and scale of the original — important if the model is going to be printed or measured.
Converting STL to PLY loses nothing that matters: what goes in is what comes out, in the format you need.
