OBJ to PLY converter

Drop a OBJ file, check the preview, download PLY. The conversion runs in your browser, so your model never leaves your device.

How the conversion works

OBJ is a text-based mesh format from the DCC world (Blender, Maya, ZBrush). It can reference materials through a separate .mtl file; this tool reads the geometry.

The converter writes binary PLY, a compact format that mesh-processing tools like MeshLab and CloudCompare handle well.

Frequently asked questions

Does my file get uploaded?

No. Parsing and export run in your browser with WebAssembly and three.js. The file stays on your device, and it works offline once the page has loaded.

What survives the OBJ to PLY conversion?

Geometry comes through completely: every triangle, at full precision. Materials, textures, and vertex colors are dropped, because PLY as written here stores plain triangles only.

Is there a file size limit?

Files up to 150 MB work. Heavier meshes convert too, they just take longer; if a file is unwieldy, reduce its triangle count first with the reduce tool.
