Convert VTK to OBJ online

Drop a .vtk file to turn it into OBJ. You see the model in 3D before converting, and the file never leaves your device.

About VTK

Visualization Toolkit (.vtk, .vtp)

VTK (.vtk, .vtp) comes from the Visualization Toolkit and ParaView: scientific meshes, often with per-point colors.

About OBJ

Wavefront OBJ

OBJ is a simple, widely supported text format for polygon meshes. Materials live in a separate .mtl file and textures in image files; there is no animation.

How it works

  1. 01

    Drop the .vtk file (with its textures or .bin/.mtl files, if any).

  2. 02

    Check the model in the 3D preview; OBJ is already selected.

  3. 03

    Click “Convert” and the .obj file downloads.

Questions

Is the VTK to OBJ converter free?+

Yes, without limits, sign-up or watermark.

Is my VTK file uploaded?+

No. The VTK file is read and converted in your browser; nothing is sent to a server.

Why are textures missing after converting VTK?+

Textures stored as separate files must be selected together with the model. OBJ keeps them only if the format supports textures.
