Questions

How do I convert GLB to 3MF?

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

Is my GLB 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.

Will the animation still play?

No: 3MF holds a single picture, so only the first frame is kept.

Can I convert several GLB files at once?

Yes. Drop them together and you get one ZIP with every 3MF inside.
