Convert PLY to OBJ
Convert a PLY scan or mesh into a Wavefront OBJ that any 3D application can open.
Free, no account, up to 50 MB per file. Uploads are private and deleted after 24 hours unless you sign in, which claims them and keeps them for 7 days.
What survives PLY → OBJ
- Geometry
- Per-vertex colours where OBJ's extended colour syntax can carry them
What is not carried across
- Materials and textures — a PLY does not carry them in the first place.
About PLY files
- PLY is common for scans and usually carries per-vertex colours rather than materials or textures.
- PLY has no scene hierarchy, so a converted result is a single object.
- Point clouds without faces are not meshes and cannot be converted.
Why OBJ
- Read by essentially every DCC application ever written; a safe interchange format.
- Plain text, so it can be inspected and diffed.
Common problems
- Vertex colours are missing in my application.
- Per-vertex colour in OBJ is an extension, and not every reader supports it. GLB carries colours more reliably.
After converting
Converting changes the container, not the geometry — a heavy model stays heavy. If the result is destined for the web or a game engine, reducing its triangle count is the part that makes it load faster.
