Our free and fast tool will convert most 3D mesh or OBJ (Wavefront) 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 OBJ files, up to 25 files at a time can be converted.
To convert your OBJ 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 OBJ to VTK conversion process see the conversion information section below for more information.
Here are 2 simple steps to convert your OBJ to VTK.
First click the "Upload..." button, select your OBJ file to upload. Select any configuration options. When the OBJ to VTK conversion has completed, you can download your VTK file straight away.
We aim to process all OBJ 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 OBJ 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 OBJ 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 OBJ 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 OBJ tool supports full batch conversions. You can upload up to 25 OBJ 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 OBJ file format originally created by Wavefront Technologies and later adopted by many other 3D software vendors is a simple text-based file format for describing 3D model/geometry. This data can include Vertices, Faces, Normals, Texture Coordinates and references to external Texture files.
As the format is text-based it is relatively straight-forward to parse by 3D modelling applications. A downside of the text-based format is the files can be rather large compared to similar binary formats such as STL and compressed files such as 3MF.
Currently our tool does not support importing materials or color information from your OBJ file.

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.
