Needed just the vertex points for a random experiment. This did exactly that without any fuss. Thanks for the niche tool.

What to know about OBJ → PLY
- OBJ is a text format; its materials and textures live in a separate .mtl file and image files.
- PLY holds a mesh or a point cloud and can store a color for every vertex.
- In MeshInspector this conversion is Open and Export, two free tools, in the web app and in the desktop app.
- OBJ stores no units, like STL.
- PLY exists in a text and a binary form.

FAQ
Do I need an account to convert OBJ to PLY?
No. The converter on this page is the MeshInspector web app running in your browser without sign-up. Click Open Files and pick your .obj file, select it in the scene list, click Export, choose .ply in the Extension list and click Save. The converted file downloads to your computer.
Is the OBJ to PLY converter free?
Yes. Opening a .obj file and exporting it as .ply use free tools, here, in the web app and in the desktop app on the free Community plan. Paid plans add tools such as Mesh Healer and automatic repair; the Pricing page lists what each plan includes.
Are colors and units kept?
PLY stores no units, so check the size of the model after conversion. PLY can store a color for each vertex; if the source has textures rather than vertex colors, expect the exported PLY to carry the geometry only. Check the result in your target app before you rely on it.
Is there a file size limit?
There is no fixed limit on this page, but the web app works within your browser's memory: up to about 4 GB, or 16 GB in browsers with 64-bit WebAssembly. For very large models, or many files, use the desktop app for Windows, macOS or Linux.
