View 3D OFF Files Online

Use this free tool to view your 3D OFF (Object File Format) files online without needing to install any software. Our OFF viewer tool will generate a real-time 3D preview of your OFF file with Pan and Zoom controls, allowing you to see your 3D model from any angle.

Our OFF viewing tool can load most OFF files, and we are working on improvements all the time to improve compatibility with all file formats. If you are looking to convert your 2D image files to 3D files, such as STL, then we have a 2D to 3D conversion tool here.

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 the storage of four-dimensional data.

The format can contain common vector information such as vertices, faces, shapes, and edge information, and it 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.
