Convert OFF files to 3MF in seconds. Geometry, UVs and materials are carried over where 3MF supports them, and the model lands the right way up.
Drop it on the converter above or click browse. It opens in your browser, so nothing is uploaded.
3MF is already selected. You can switch to any other output from the menu.
Click Convert and your 3MF file is ready in seconds. Download it straight away.
OFF is a simple text mesh format used in geometry research, teaching and tools such as Geomview and CGAL.
3MF is the modern 3D printing format from the 3MF Consortium. Unlike STL it records units, colours and multiple objects in one compressed file, and it is the native project format of Bambu Studio and PrusaSlicer.
Colours and texture coordinates are carried over when 3MF supports them. 3MF does not store textures, so only the geometry and colours carries over.
No. OFF and 3MF may use different "up" directions, and we rotate the model so it stands the same way in your software.
No. The conversion runs inside your browser.
