Free Online VTK to OBJ Converter

You can use our VTK to OBJ conversion tool to quickly and easily convert your 3D model files for free. You may upload up to 20 files at one time, and our batch VTK to OBJ converter will process each 3D model and present you with a download link for each file once completed.

Select File(s)

Or drag and drop your files here to upload.
A maximum of 20 files can be uploaded at once.

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

Our 3D model VTK to OBJ tool will load your VTK file and, where supported, attempt to extract all the relevant 3D features, such as geometry, textures, and animations. To access the 3D conversion configuration options, click the button when you have selected your files. The current options support the ability to voxelize your 3D model and more.

Frequently Asked Questions

How can I convert my VTK file to OBJ?

First, click the "Upload..." button and select your VTK file to upload. Your VTK file will be uploaded to our servers. When the VTK to OBJ conversion has completed, you can download your OBJ file right away.

How long does it take to convert my VTK to OBJ?

We aim to process all VTK to OBJ conversions as quickly as possible; this usually takes around 5 seconds; however, this can be longer for certain files, so please be patient.

How accurate is the VTK to OBJ conversion?

We aim to provide the best conversion experience. Our tools are under constant review and development, with new features being added every week.

How does converting VTK to OBJ work?

In order to successfully convert an VTK formatted file to the OBJ format, our converter tools will perform several initial checks to ensure the file provided is indeed an VTK file. There are many files out there where the file type extension does not match the data contained within the file. Along with these file type checks, our tools will do additional checks to ensure the file is correctly formatted to match the provided file type. There are many tools out there that do not always create VTK files to the exact specification.

Take your VTK file

An VTK file is a binary data file containing 3D data that makes up the 3D model, including vertices, faces, texture coordinates, and more. To guarantee efficient conversions, our tool will check all data that is contained within the VTK file and remove any information that is duplicated. This not only ensures the conversion completes more quickly, but also the generated OBJ file size is smaller.

Convert the data from VTK to OBJ

Now that the data from the VTK file has been processed, our tool can apply any conversion specified options, such as enabling Voxel mode, and with these applied, prepare the data to be converted to the final OBJ file format. Part of this process ensures checking the capabilities of the OBJ format and removing any data that cannot be represented.

Save to the OBJ format

At this point, the VTK to OBJ conversion tool will have the 3D model in a state that is ready to be transferred to the OBJ format. Our tool creates the OBJ file, ensuring all the model data is present and is formatted to match the OBJ file specification to ensure the file opens in compatible OBJ file editors.

File format information for VTK and OBJ

Extension	VTK
Full Name	Visualization Toolkit
Type	3D Model
Mime Type	application/octet-stream
Format	Binary

VTK files (Visualization Toolkit) are a 3D graphics format used to store 3D models and scientific visualizations in a format that is easy to integrate into 3D rendering systems.

The VTK format consists of a header section that describes the data structure and fields present in the main content. The actual 3D content can be stored as either plain ASCII text or binary, with the binary option offering the most efficient use of storage space.

There are several VTK viewing applications available, and our own set of VTK conversion tools can convert to and from other common 3D formats, such as OBJ.

VTK Converter Capabilities

Our VTK 3D Model/Mesh tool does not support any colour material data contained within VTK files, so the converted file will not contain any colour information.

Extension	OBJ
Full Name	Wavefront
Type	3D Model
Mime Type	text/plain
Format	Text
Opens With	MeshLab, CAD Assistant, DAZ Studio

The OBJ file format is a 3D graphics file format used to define complex 3D models, including geometry, materials, and textures. OBJ files are text files, making them human-readable and easy to modify by hand. The downside to this ease of readability is that the files can become rather large when dealing with large or complex 3D models.

As mentioned, the OBJ format stores not only 3D model geometry but also materials and textures. These materials are usually defined in a separate file with the MTL file extension and specify geometry rendering details such as diffuse and specular colour, transparency, and much more.

The OBJ material file can also reference external texture files. These are usually JPEG or PNG files; however, these can be older formats, such as TGA. Where materials are used, the OBJ file will also contain material names preceding the geometry faces they should be applied to. If textures are referenced, the geometry will also contain texture coordinates (UV) for each vertex.

OBJ Converter Capabilities

Our 3D conversion tool does not support colour or material information in OBJ files, so your file will not contain any colour information.

Information for converting from VTK to OBJ

Your VTK file will be converted to a OBJ file using our unified 3D model and mesh conversion tool. Our VTK 3D tool performs accurate conversions of 3D elements such as vertices, faces, normals, and relevant material information. Our tool will not attempt to transfer any colour information if it is present in your VTK file; your final 3D model will contain only geometry data.
