Questions

How do I convert 3MF to STL?

Drop your 3MF file on this page, or choose it. Anyfile converts it on your device in a moment and the STL downloads straight away. To change it first, open it in the 3D viewer.

Is my 3MF file uploaded anywhere?

No. The file is read and converted by your own browser, and nothing is sent to a server. You can check: open your browser’s developer tools, go to Network, and convert a file. No upload appears.

Can I convert several 3MF files at once?

Yes. Drop them together and you get one ZIP with every STL inside.
