Drop a .obj below and download it as a binary PLY, ready for MeshLab, CloudCompare, Open3D or any geometry-processing pipeline. The conversion runs locally in your browser — nothing is uploaded.

OBJ comes from DCC tools; PLY is what mesh-processing and point-cloud software prefers. One click converts.
Compact binary encoding that loads fast in MeshLab, CloudCompare, Open3D and trimesh.
three.js parses and re-exports the mesh in browser memory — no upload, no queue.
Drag the .obj file in — the geometry renders as a live preview.
One click re-encodes the mesh as binary PLY.
Load the .ply into your processing tool or Python geometry script.
Geometry-processing tools and libraries — MeshLab, CloudCompare, Open3D, PCL, trimesh — are built around PLY because it stores arbitrary per-vertex attributes efficiently. If you're measuring, decimating, comparing against a scan, or feeding a mesh into a research or inspection pipeline, PLY is the path of least resistance. OBJ, designed for modeling interchange, often needs a conversion step first — this is that step.
The full triangle geometry with normals converts one-to-one. OBJ's materials live in a separate .mtl file that a browser tool can't read from your disk, and PLY has no material system anyway — so the output is clean geometry, which is precisely what processing tools operate on.
Yes. Free and unlimited, no account required.
No — the file is converted in your browser's memory and downloaded directly.
Binary, for smaller files and faster loading. If a legacy tool insists on ASCII PLY, MeshLab can re-save it in one step.
PLY has no standard UV or material system, so the output is geometry with normals — which is what processing pipelines consume.
