Our free and fast tool will convert most 3D mesh or 7Z (7z Archive) model files to a standard 3MF (3D Manufacturing Format) file that can then be edited further in most popular 3D editing packages such as Blender or 3D printed without any further processing. Our conversion tool can also batch convert multiple 7Z files; up to 25 files at a time can be converted.
To convert your 7Z file, click the Upload button above and select the file to convert. Once selected, the file will be converted to a 3MF file and will be ready for download shortly afterwards. For more information about the 7Z to 3MF conversion process, see the conversion information section below.

7Z files are file containers used to compress multiple files using a variety of compression algorithms. The compression achieved is dependent on the type of file being compressed and the chosen algorithm.
It supports very large file sizes (a maximum of 16 exbibytes) and can combine similar files into a single compression operation to achieve a more optimal compression ratio.

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 and compressed with 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 files support material and color information. If your uploaded model contains color information, our tool will attempt to save this in the 3MF file at the end of the conversion process. Textures are supported and will be included in the final 3MF file.
First click the "Upload..." button, select your 7Z file to upload. Select any configuration options. When the 7Z to 3MF conversion has completed, you can download your 3MF file straight away.
We aim to process all 7Z to 3MF conversions as quickly as possible, this usually takes around 5 seconds but can be more for larger more complex files so please be patient.
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.
Yes, of course! We do not store the 7Z file you submit to us. The resulting 3MF file, once created is deleted 15 minutes after upload and the download link will expire after this time.
No. All our conversion tools process your 7Z file on our dedicated conversion servers, meaning you can use our tools on low-spec computers, laptops, tablets, and mobile devices and receive your converted 3MF file quickly.
Yes! Our 7Z to 3MF tool will run on any system with a modern web browser. No specialist software is needed to run any of our conversion tools.
Yes. Although you can use an Ad Blocker, if you like our 7Z 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.
Yes. When you have converted your 7Z to 3MF, there is a "Feedback" option that you can use to let us know of any issues you encountered when converting your file.
