Our free and fast tool will convert most 3D mesh or STEP (STEP-File) 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.
To convert your STEP 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 ready for download shortly afterwards. For more information about the STEP to VTK conversion process see the conversion information section below for more information.
Here are 2 simple steps to convert your STEP to VTK.
First click the "Upload..." button, select your STEP file to upload. Select any configuration options. When the STEP to VTK conversion has completed, you can download your VTK file straight away.
We aim to process all STEP 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 STEP file you submit to us. The resulting VTK file, once created is deleted 1 hour after upload and the download link will expire after this time.
Yes! Our STEP 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 STEP 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.

The STEP file format is a 3D format defined in 1994 and used to store 3D objects for use in Computer-aided design (CAD) applications. STEP files are text-based formatted files containing one instance per line.
Although STEP files are widely supported by most CAD applications the format does have its limitations, such as the necessity to read the complete file into memory in order to parse the contents and due to the text storage of information the files can be quite large.
STEP files when imported will be converted to 3D geometry comprising vertices and faces. If the STEP file contains color information this will be converted where possible.

The VTK file format is a 3D modelling 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 modelling applications. Some example functions of the toolkit include polygon simplification, mesh repair and smoothing and more.
The format has evolved over the years. Starting 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.
