This is our free-to-use 3MF file conversion tool that can be used to convert your 3MF file into any number of other 3D model formats. Our 3MF converter will extract the 3D model geometry contained within your file and accurately convert it to the desired format without any loss of detail. Our 3MF converter also has a batch processing mode whereby you may upload up to a maximum of 20 files to be converted in one go.

Drag and drop your files here to upload or click the button above.
A maximum of 20 files can be converted at once.

Please note: Your 3MF file file, when uploaded to our server, will be deleted 15 minutes after upload. Please download your converted 3MF file file before this time.
Our 3MF conversion tool supports converting to the following file types:

Our 3MF converter will extract the vertices, faces, and other geometric data that forms the structure of your 3D model and convert it to the requested format. If the selected format supports external texture files, these can be uploaded along with your 3MF model file, and these will be processed accordingly.

3MF file information

Mime Typeapplication/

The primary purpose of the 3MF format is to store and transmit 3D models for 3D printing. The format is ideally suited to this due to its ability to store not only the 3D model but also additional metadata required for 3D printing an object, such as units of measurement, surface material characteristics, and more.

Mesh Geometry

The 3MF file format is a mesh-based format; more specifically, the mesh is stored as a series of triangles that, when combined, can represent any 3D object. The format can contain many 3D mesh objects in a single file.


3MF files can contain material colors that can be applied to individual mesh triangles or even individual vertices. 3MF files can also contain surface textures; if these are present, there will be separate text coordinate mapping data included in the main mesh definition files.

The 3MF file stores any textures as separate files, usually in common image formats like PNG and JPG. These texture files are embedded within the main 3MF file.

3MF Converter Capabilities

As materials containing texture and color information are both supported by the 3MF format, our tool will do its best to include these materials, including any texture files, in the converted file.
