Convert Your 3D Mesh/Model 3MF Files to OFF

to

Our free and fast tool will convert most 3D mesh or 3MF (3D Manufacturing Format) 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 3MF 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 3MF to OFF conversion process see the conversion information section below for more information.

Upload a 3MF

Click the "Upload a 3MF File" button and select a 3MF to upload. The maximum file size is 100MB.

Download your OFF

Click the download link once completed to receive your OFF file.

How can I convert my 3MF file to OFF?

First click the "Upload..." button, select your 3MF file to upload. Select any configuration options. When the 3MF to OFF conversion has completed, you can download your OFF file straight away.

How long does it take to convert my 3MF to OFF?

We aim to process all 3MF 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.

How accurate is the 3MF to OFF conversion?

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.

Is it safe to convert my 3MF to OFF on ImageToStl.com?

Yes, of course! We do not store the 3MF 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.

Can I convert 3MF to OFF on Windows, Linux, Android, iOS or Mac OS?

Yes! Our 3MF 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.

What if I am using an Ad Blocker, will that affect things?

Yes. Although you can use an Ad Blocker, if you like our 3MF 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.

File format information for 3MF to OFF

Extension	3MF
Full Name	3D Manufacturing Format
Type	3D Model
Mime Type	application/vnd.ms-package.3dmanufacturing-3dmodel+xml
Format	Binary

Description

3MF files are a modern 3D file format designed specifically for use with 3D printable models (additive manufacturing). It was designed to be the successor to the popular legacy STL format (also a common format in 3D printing) to overcome the limitations of that format.

The format of 3MF files is XML based that are compressed with the standard Zip file compression resulting in small, easily transferable files. The format supports 3D meshes along with associated materials and textures all contained within the Zip file.

3MF Notes

If your 3MF file contains textures, these will be ignored. If a material contains color information this will be translated where possible.

Supported Features

Mesh geometry
Face and vertex colors

Unsupported Features

Description

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 Notes

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.
