Convert OBJ to PLY Online
Convert OBJ to PLY in seconds. OBJ is the Wavefront geometry-plus-material format; PLY's strength is this: can store per-vertex color and custom properties directly on the mesh. No software installation required — everything runs in your browser.

Why Convert OBJ to PLY?
This conversion comes up whenever you need 3D scanning output, carrying per-vertex color alongside geometry instead of broad, simple mesh exchange across nearly every 3D application. OBJ and PLY serve genuinely different purposes, so moving between them isn't just a formality.
The short version: OBJ is optimized for broad, simple mesh exchange across nearly every 3D application, PLY is optimized for 3D scanning output, carrying per-vertex color alongside geometry, and this converter exists for the moment those two needs don't line up.
OBJ's limitation: no animation, rigging, or scene hierarchy support. PLY's strength: can store per-vertex color and custom properties directly on the mesh — it doesn't share that constraint.
How to Convert OBJ to PLY
- Upload your OBJ file.
- MiConvert converts it to PLY, aiming to preserve what makes PLY useful: can store per-vertex color and custom properties directly on the mesh.
- Download the converted PLY file.
- Use it directly with 3D scanners and scan-processing software.
Key Conversion Features
- No local software installation required for either side — not virtually every 3D and rendering application, not 3D scanners and scan-processing software — everything runs in the cloud
- Converts OBJ into PLY, aiming to preserve what matters most: can store per-vertex color and custom properties directly on the mesh
- Keeps the parts of your file that matter for 3D scanning output, carrying per-vertex color alongside geometry intact, even though the source was built for broad, simple mesh exchange across nearly every 3D application
- Bridges the gap between OBJ's focus on broad, simple mesh exchange across nearly every 3D application and PLY's focus on 3D scanning output, carrying per-vertex color alongside geometry
- Understands that OBJ is the Wavefront geometry-plus-material format and PLY is the Stanford Triangle Format, rather than treating the conversion as a blind format swap

Frequently Asked Questions
Why would I need PLY instead of just keeping OBJ?
Mainly when your workflow specifically calls for 3D scanning output, carrying per-vertex color alongside geometry — that's PLY's whole reason for existing, and OBJ isn't built to provide it, since it's focused on broad, simple mesh exchange across nearly every 3D application instead.
What's the real difference between OBJ and PLY?
OBJ is built around broad, simple mesh exchange across nearly every 3D application (the Wavefront geometry-plus-material format). PLY is built around 3D scanning output, carrying per-vertex color alongside geometry instead (the Stanford Triangle Format) — different enough that this is a genuine format conversion, not just a rename.
Is PLY objectively better than OBJ?
Not objectively — PLY is better specifically for 3D scanning output, carrying per-vertex color alongside geometry. For broad, simple mesh exchange across nearly every 3D application, OBJ is still the right tool; that's exactly why both formats exist.
Is this conversion free?
Yes — free for files up to 50MB, with a 100MB limit for registered accounts, no subscription required.
Why does PLY exist as a separate format instead of everyone just using OBJ?
Because they're built for different jobs — OBJ is aimed at broad, simple mesh exchange across nearly every 3D application, while PLY is aimed at 3D scanning output, carrying per-vertex color alongside geometry. Neither format is "better," they just fit different parts of a workflow.
