PLY vs OBJ— what's the difference?

PLY.ply

Stanford Polygon format — the preferred mesh format for 3D scanning, photogrammetry, and point clouds.

Strengths
  • Stores per-vertex colour, normals, and custom attributes
  • Handles both meshes and raw point clouds
  • Compact binary mode available
Limitations
  • Less common in art / game pipelines
  • No material or texture references
Typical use: 3D scanning, photogrammetry, research datasets
OBJ.obj

Human-readable Wavefront mesh format — ubiquitous in 3D graphics, game art, and asset pipelines. Pairs with a .mtl material file.

Strengths
  • Supported by virtually every 3D tool (Blender, Maya, 3ds Max, Unity, Unreal…)
  • Plain-text, easy to diff and hand-edit
  • Keeps UV coordinates and vertex normals, unlike STL
  • Material references via companion .mtl file
Limitations
  • Text format — larger on disk than binary meshes
  • No scene hierarchy, no animation, no skeletons
  • Materials live in a separate file; easy to lose
Typical use: 3D art pipelines, DCC handoff, asset archives

How to convert PLY to OBJ

  1. 1
    Drop a .ply file onto the page. Both ASCII and binary-little-endian PLY parse natively.
  2. 2
    Preview the mesh (or point cloud) in 3D — inspect vertex colour and topology before converting.
  3. 3
    Click Download .OBJ. Open directly in Blender, Maya, 3ds Max, or any Wavefront-aware viewer.

FAQ

Why convert PLY to OBJ?

PLY is the canonical scan / photogrammetry format (RealityCapture, Meshroom, Agisoft all export it). OBJ is the canonical DCC format. Converting lets you take a scan into Blender or ZBrush without a plugin.

Will vertex colours come across?

OBJ has no per-vertex colour channel in the base spec. Colour data from the PLY is dropped during conversion. If you need colour, convert PLY → GLB instead (GLB stores vertex colour as a PBR attribute).

What about point clouds?

OBJ is a face-based format — it cannot represent pure point clouds. If your PLY is a raw point cloud without faces, the resulting OBJ will be empty. Mesh your scan first (Meshlab, Blender remesh, etc.) before converting.

Are UV coordinates preserved?

If the PLY includes UV (most scanner exports do not), the OBJ writer emits vt lines. Textures are not moved — a companion .mtl is not generated.

Is anything uploaded?

No. The PLY is parsed in your browser and re-exported as OBJ locally. The file never leaves your device.
