FAQ
Do I need an account to convert PLY to OBJ?
No. The converter on this page is the MeshInspector web app running in your browser without sign-up. Click Open Files and pick your .ply file, select it in the scene list, click Export, choose .obj in the Extension list and click Save. The converted file downloads to your computer.
Is the PLY to OBJ converter free?
Yes. Opening a .ply file and exporting it as .obj 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?
OBJ stores no units, so check the size of the model after conversion. Colors and textures in OBJ live in a separate .mtl file and image files; the exported OBJ carries the mesh geometry, so check the result in your target app if you rely on materials or textures.
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.
