Our free and fast tool will convert most 3D mesh or PLY (Stanford Triangle Format) model files to a standard VTK (Visualization Toolkit) file that can then be edited further in most popular 3D editing packages such as Blender or 3D printed without any further processing. Our conversion tool can also batch convert multiple PLY files; up to 25 files at a time can be converted.
To convert your PLY file, click the Upload button above and select the file to convert. Once selected, the file will be converted to a VTK file and will be ready for download shortly afterwards. For more information about the PLY to VTK conversion process, see the conversion information section below.

The PLY format is a 3D model format originally developed and released in 1994, with its primary use being to store three-dimensional data from 3D digital scanners. The format known as the Polygon File Format or the Stanford Triangle Format can be either a binary or text-based format.
The file format stores 3D geometric information such as vertices, faces, vertex normals, color, and other custom data. The format is still in use, with many PLY models available to download, and PLY files can be loaded into most popular 3D applications, such as Blender.
If your PLY file contains vertex colors, these will be imported and mapped where possible.

The VTK file format is a 3D modeling and graphics format supported by the Visualization Toolkit. Created in the '90s, the Visualization Toolkit provides a series of data and visual tools for advanced 3D modeling applications. Some example functions of the toolkit include polygon simplification, mesh repair and smoothing, and more.
The format has evolved over the years. It started out as a simple text-based format that could be edited within a simple text editor. Additional features have been added over the years, with the most recent version of the format supporting an XML-based format.
Any model converted to the VTK format will be stored in a triangulated mesh format.
Converting from the PLY file format to VTK can be a complex process, and any tool used for this conversion process needs to be able to handle a variety of data conversion tasks as well as identify any defects within the 3D model and fix them. Here we will explain the conversion process used by our tool to accurately convert your PLY file to a valid VTK 3D model. Let's start with the conversion process, which involves the following steps:
In its simplest form, an PLY file can be either a plain text or binary file containing 3D data such as vertices, faces, normals, and more. When combined, these make up the 3D model you see on your screen.
For more information regarding the PLY file format, please see this great article that goes into a lot of detail explaining the PLY format.
With the PLY file data read, our tool generates an internal representation of the full 3D model and will attempt to fix any geometry issues encountered. Along with repairing any issues with the 3D model, the tool will remove any duplicated vertices and prepare the model for exporting to the VTK format.
With the conversion process entering its final stages, our tool now needs to take the in-memory 3D model we have created in step 2 and convert it to the VTK format.
Our tool supports converting from all PLY formats including Text and Binary (both little endian and big endian).
We aim to process all PLY to VTK conversions as quickly as possible, this usually takes around 5 seconds but can be more for larger more complex files so please be patient.
We aim to create the most accurate conversions with our tools. Our tools are under constant development with new features and improvements being added every week.
Yes, of course! We do not store the PLY file you submit to us. The resulting VTK file, once created is deleted 15 minutes after upload and the download link will expire after this time.
No. All our conversion tools process your PLY file on our dedicated conversion servers, meaning you can use our tools on low-spec computers, laptops, tablets, and mobile devices and receive your converted VTK file quickly.
Yes! Our PLY to VTK tool will run on any system with a modern web browser. No specialist software is needed to run any of our conversion tools.
Yes. Although you can use an Ad Blocker, if you like our PLY conversion tool please consider white-listing our site. When an Ad Blocker is enabled there are some conversion limits on some of our tools and processing/conversion times will be longer.
Yes. When you have converted your PLY to VTK, there is a "Feedback" option that you can use to let us know of any issues you encountered when converting your file.
