Free Online OBJ to PLY Converter

Here is our free to use OBJ to PLY 3D model converter tool that will take your OBJ file and convert it to the PLY format ready for loading into your favourite 3D modeling package. If you have any external texture files, these can be selected along with your OBJ file and our tool will automatically handle converting these. Our 3D model converter supports batch processing of your files and can convert up to 20 OBJ files at one time.

Select File(s)

Drag and drop your files here to upload or click the button above.
A maximum of 20 files can be converted at once.

Please note: Your OBJ file file, when uploaded to our server, will be deleted 15 minutes after upload. Please download your converted OBJ file file before this time.

The OBJ to PLY model conversion tool will analyse your OBJ file and convert its 3D mesh data including vertices, surfaces and where applicable vector normals and texture coordinates to the PLY format whilst maintaining the structural accuracy of your original OBJ 3D model file.

File information for OBJ and PLY

Full Name	Wavefront
Extension	OBJ
Type	3D Model
Mime Type	text/plain
Format	Text

An OBJ file is a text-based file format used for the storage of 3D model data. The format was developed in the 1980s by Wavefront Technologies as a means to store the geometric mesh data associated with a 3D model. It has garnered widespread support in the following years, and you will find options to load from and save to the OBJ format in most modern 3D modeling applications.

As OBJ files are essentially text files, they can grow quite large when working with large and detailed 3D models.

Mesh Geometry

Within a 3D OBJ file are lists of vertices, mesh faces, face normals, texture coordinates, and more. The vertices, normals, and texture coordinates are stored in a continuous list and are indexed referenced within a separate list of mesh faces, ensuring optimal use of space within the file. A mesh face may contain three or more points, each of which can use a unique vector normal and texture coordinate.

OBJ Converter Capabilities

As materials containing texture and color information are both supported by the OBJ format, our tool will do its best to include these materials, including any texture files, in the converted file.

Full Name	Stanford Triangle Format
Extension	PLY
Type	3D Model/Point Cloud
Mime Type	application/octet-stream
Format	Text

The PLY file format, commonly referred to as the Stanford Triangle Format, is a 3D file format that comes in either plain text or binary formats. The PLY format is a mature format and is supported by many popular 3D editing applications.

Due to its ability to handle full-color 3D point clouds, the format is commonly used as a medium of exchange when working with 3D scanners. There are also many 3D models available online in the PLY format.

PLY Converter Capabilities

As materials containing color information is supported by the OBJ and PLY formats, our tool will do its best to include this in the converted PLY file.

Frequently Asked Questions

How do I convert my OBJ to PLY?

First, click the "Select File" button and choose your OBJ file. We will upload and convert your OBJ file. Once the conversion from OBJ to PLY completes, use the provided link to download your PLY file.

How long does it take to convert my OBJ file to PLY?

We aim to process all OBJ to PLY file conversions as soon as possible; this should take around 5 seconds; however, this may be longer for larger files.

Is the OBJ format suitable for 3D printing?

No. Most 3D printing slicer software will not support the OBJ format. It is recommended to convert your OBJ file to the STL format if you wish to 3D print it.
