Our free and fast tool will convert most 3D mesh or VRML (Virtual Reality Modeling Language) 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 VRML files; up to 25 files at a time can be converted.
To convert your VRML 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 VRML to VTK conversion process, see the conversion information section below.
Here are two simple steps to convert your VRML to VTK.
First click the "Upload..." button, select your VRML file to upload. Select any configuration options. When the VRML to VTK conversion has completed, you can download your VTK file straight away.
We aim to process all VRML 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 VRML 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.
Yes! Our VRML 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 VRML 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! Our VRML tool supports full batch conversions. You can upload up to 25 and VRML files at a time. Our tool will convert them all as quickly as possible. Once completed, you can either download the VTK files individually or download them all in a single ZIP file.

The VRML file format is a 3D-based model format originally created in the 1990's that was aimed at website usage. The format is text-based and contains 3D geometry data such as vertices, faces, simple shapes, material information, and more.
This format, when launched, was hoped to become a standard 3D format; however, due to the large file sizes, it didn't see wide adoption, although it is a supported format within some CAD software applications. It was later superseded by the X3D file format, which shares most of the functionality of VRML files.
If your VRML file contains textures, these will be ignored. If a material contains color information, this will be translated 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 VRML 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 VRML file to a valid VTK 3D model. Let's start with the conversion process, which involves the following steps:
In its simplest form, an VRML file is a plain text file containing human-readable 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 VRML file format, please see this great article that goes into a lot of detail explaining the VRML format.
With the VRML 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.
