Free converter

Convert OBJ to PLY in your browser.

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.

Why this tool

Free, private, in the browser.

Modeling format to processing format

OBJ comes from DCC tools; PLY is what mesh-processing and point-cloud software prefers. One click converts.

Binary PLY output

Compact binary encoding that loads fast in MeshLab, CloudCompare, Open3D and trimesh.

Nothing leaves your machine

three.js parses and re-exports the mesh in browser memory — no upload, no queue.

How it works

Three steps, no setup.

01
Drop your OBJ

Drag the .obj file in — the geometry renders as a live preview.

02
Convert to PLY

One click re-encodes the mesh as binary PLY.

03
Analyze or process

Load the .ply into your processing tool or Python geometry script.

Why convert OBJ to PLY?

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.

What transfers

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.

Questions

Answered, plainly.

Is the OBJ to PLY converter free?+

Yes. Free and unlimited, no account required.

Is anything uploaded?+

No — the file is converted in your browser's memory and downloaded directly.

ASCII or binary PLY?+

Binary, for smaller files and faster loading. If a legacy tool insists on ASCII PLY, MeshLab can re-save it in one step.

Are UVs and materials kept?+

PLY has no standard UV or material system, so the output is geometry with normals — which is what processing pipelines consume.
