Convert PLY to STL
Drop your PLY files and download them as STL — free, in batch, and they never leave your device.
PLY → STL: what you should know
PLY is a mesh or point-cloud format that can store per-vertex color — typical of 3D scanners. It's used mostly in 3D scanning, photogrammetry, mesh processing (MeshLab, CloudCompare), and it stores geometry, normals and per-vertex colors. STL, on the other hand, is the standard format of 3D printing: a triangle mesh with no explicit units, no color and no materials — the format expected by slicers (Cura, PrusaSlicer, Bambu Studio), FDM and resin 3D printing, CAD.
This tool converts your PLY files to STL 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.
Keep in mind: STL doesn't support vertex colors: if your PLY has them, they'll be lost. If you need to keep that data, convert to a format that supports it (GLB keeps materials and textures; PLY keeps vertex colors).
