Convert OBJ to PLY Online — Free
Upload a Wavefront OBJ file and download it as Polygon File Format. Runs entirely in your browser — no server uploads.
About These Formats
Wavefront OBJ
OBJ is a simple, human-readable text format that stores 3D geometry (vertices, faces, texture coordinates, and normals). It is one of the most universally supported formats.
Used with
Blender, Maya, Cinema 4D, 3ds Max, ZBrush, and virtually any 3D application.
Polygon File Format
PLY is a flexible format for storing 3D polygon meshes. It supports vertex colors, custom properties, and is commonly used for 3D scan data and point clouds.
Used with
3D scanning, photogrammetry, research, point cloud processing (MeshLab, CloudCompare).
What Transfers from OBJ to PLY
A breakdown of which data survives the OBJ-to-PLY conversion.
3D Geometry
Vertices, faces, and normals always transfer
Textures & Materials
PLY is geometry-only — textures are discarded
Animations
OBJ does not store animations
Vertex Colors
OBJ does not support vertex colors
Multiple Objects
Multiple meshes merged into one on export
When to Convert OBJ to PLY
Convert OBJ to PLY when you need to work with point cloud data or use tools like MeshLab, CloudCompare, or Open3D. PLY is flexible and supports custom vertex attributes including per-vertex colors from scanned data.
OBJ to PLY — What to Know Before Converting
PLY stores raw triangulated geometry with no colour, material, or texture data. Save your original textures separately before converting if you need them for other pipelines.
OBJ references textures via a companion MTL file — the converter needs both to preserve materials. If only the OBJ is uploaded without its MTL and texture images, the output will be an untextured mesh.

Tips for the Best OBJ to PLY Result
Binary PLY is significantly smaller than ASCII PLY — prefer binary output when storing or transferring files.
Verify your target tool reads the PLY property names you expect; some tools are strict about header ordering and property names.
Open3D, MeshLab, and CloudCompare all read PLY natively — it is the most compatible format for Python-based 3D processing pipelines.
To convert PLY vertex colors to UV-mapped textures for game or AR use, open the file in MeshLab and run "Transfer Vertex Color to Texture".
Common Reasons to Convert OBJ to PLY
- →3D scanning and photogrammetry: PLY is the standard output of LiDAR scanners, structured-light scanners, and photogrammetry pipelines
- →Research and academic work: PLY's flexible property support makes it ideal for datasets with per-point labels, normals, or curvature values
- →Python 3D pipelines: Open3D, trimesh, and pyntcloud all read and write PLY natively
- →Point cloud processing: MeshLab and CloudCompare use PLY as their primary interchange format
Frequently Asked Questions
How do I convert OBJ to PLY?
Upload your .obj file using the tool above, confirm the source format is set to OBJ and the target is PLY, then click Convert. The file processes in your browser and you can download it immediately.
Does converting OBJ to PLY preserve textures?
PLY stores geometry only. Textures and materials will not be included in the output.
Is this converter free?
Yes, completely free. No account, no usage limits, no hidden fees.
Are my files uploaded to a server?
No. All processing happens locally in your browser using WebGL. Your files never leave your device.
