To convert other file formats to the "3D Polygon Mesh File" file type, you need software like MeshLab or a similar tool.
About OFF files
The .OFF (Object File Format) is a text-based or binary format designed to store 3D polygon mesh data, focusing purely on geometry like vertices, faces, and edges rather than complex textures or animations. Originally developed for Geomview, it is heavily utilized in academic research and supported by mesh-processing software like MeshLab. A secondary, unrelated use for .OFF files is as GAEB construction tender offer files, which are XML documents used in the German construction industry to exchange bidding data. While .OFF files are excellent for pure geometric processing due to their simple structure, they present severe disadvantages for modern 3D pipelines. The format lacks support for advanced materials, UV mapping, skinning, and rigging. Mainstream 3D suites like Blender or Autodesk Maya do not natively import .OFF without dedicated add-ons, leaving users stuck with an unreadable file. The GAEB version similarly suffers from strict regional lock-in and requires specialized German bidding software to read. To overcome these workflow blockers, you must convert the file. For 3D use, convert .OFF to OBJ for universal software compatibility, STL for 3D printing, or PLY for handling raw 3D scanner data. For GAEB files, converting to XML or CSV unlocks the data for spreadsheet applications. Just drag and drop your file here to analyze and convert it securely right in your browser.
Use Convert.Guru to open and convert your OFF file.
If you want to convert OFF file to DAE, MAX, BLEND, MA, MB, C4D or WRL, you can use MeshLab or similar software from the "3D Geometry Data Storage" category. In the File menu, look for Save As… or Export….
To convert DWG, DAE, X3D, IGES, WRL, JT, SKP, 3DS, 3DM, OBJ, STEP or FBX files to OFF, try MeshLab or another comparable tool in the "3D Geometry Data Storage" category.
The OFF Converter Story
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.
