Our free and fast tool will convert most 3D mesh or X (Direct X File) model files to a standard OFF (Object File Format) 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 X file click the Upload button above and select the file to convert. Once selected, the file will be converted to a OFF file and will ready for download shortly afterwards. For more information about the X to OFF conversion process see the conversion information section below for more information.
Here are 2 simple steps to convert your X to OFF.
First click the "Upload..." button, select your X file to upload. Select any configuration options. When the X to OFF conversion has completed, you can download your OFF file straight away.
We aim to process all X to OFF 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 X file you submit to us. The resulting OFF file, once created is deleted 1 hour after upload and the download link will expire after this time.
Yes! Our X to OFF 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 X 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 X 3D file format extension was introduced by Microsoft with the launch of Version 2 of their 3D graphics API Direct X back in 2002. The format has evolved over the years however in 2014 the X file format was deprecated in favour of newer more capable formats such as FBX.
The format is a simple text based file capable of storing 3D mesh information such as vertices, faces, normals and material information. In addition to basic 3D information the format can also store animations with the X file format primarily used in the development of games.
If your X file contains textures, these will be ignored. If a material contains color information this will be translated where possible.

The OFF file format is a simple text-based format capable of storing 2D and 3D geometry and was originally developed for the Geomview application. There is also an extension to the OFF format used by the Stella4D application to enable storage of four-dimensional data.
The format can contain common vector information such as vertices, faces, shape, edge information and also has support for including color information. As the format is text based the files can become rather large with no built-in compression options available.
OFF files support per face color information. If your uploaded model contains color information our tool will attempt to save this in the OFF file at the end of the conversion process.
