Frequently asked questions
Is my 3MF file uploaded?
No. The file is read by your browser and shown on your own device. Nothing is sent to a server, and it is gone when you close the tab.
How do I open a 3MF file without installing software?
Drop the .3mf file on this page. It opens straight away in the 3D Model Viewer, on Windows, macOS, Linux, Android and iPhone alike.
What if my 3MF file doesn't open?
The viewer checks the file's content, not just its name. If it is damaged or not really a 3MF file, you'll see an error or can switch to the hex view to look at the raw bytes.
