Convert OFF files online for free
The converter easily converts your OFF file to various formats - free and online. No Blender or extra software needed.
The converter also works in reverse, so you can convert other 3D formats to OFF with high quality output.
The .OFF (Object File Format) is a simple, text-based standard used to represent the geometry of a 3D model by specifying vertices, faces, and edges. Originally developed for the Geomview visualization software, it remains popular in academic research and computational geometry for exchanging raw mesh data.
While .OFF files are excellent for storing basic geometric structures, they pose significant challenges in modern workflows. As an ASCII (text) format, .OFF files are significantly larger than binary equivalents, making them slow to load and inefficient for storage. They typically lack support for complex scene data like rigid body animations, advanced materials, or lighting, which are standard in formats like FBX or USD. Furthermore, most mainstream operating systems and 3D engines (such as Unity or Unreal Engine) cannot preview or import these files natively.
To make your 3D data usable, conversion is often the necessary first step. For 3D printing, convert your .OFF files to STL, which is the industry standard for slicers. For use in modeling software like Blender or Maya, converting to OBJ or PLY ensures better compatibility while preserving mesh integrity. If you are dealing with GAEB construction tenders (a secondary use of the extension), these are actually XML-based data files and require specific German construction software.
Use Convert.Guru to open and convert your OFF file.
Users also converted JPG, DOCX, ALBUM, X, LWO and STL files.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our OFF converter.
