A 3MF, for a slicer that wants STL.
Turn a 3MF into an STL in your browser, nothing uploaded: at the size the 3MF says, in millimetres and standing on Z, checked before you download it.

Most slicers take 3MF now, but some machines, services and older programs still want STL. KeepSimp writes one from a 3MF in your browser, at the size the 3MF says.
Drop the 3MF and download the STL.
Open 3MF to STL and drop the .3mf on it. Its unit is read from the file, so there is nothing to guess. Press Download STL.
Before the file is offered, KeepSimp opens it again with its own reader and counts its triangles and measures its size; a file that does not match the model is not offered, and the page says what was wrong.
What changes.
The STL is written in millimetres, standing on Z, as the 3MF stood. Its parts become one shape, and colours are left out, since STL holds neither. Slicer settings in a project 3MF are not read or carried.
Going back to 3MF.
An STL can be turned into a 3MF too, which then says its unit in the file.
