Coordinates and scale are preserved exactly as they are.

Convert 3MF to STL

Drop your 3MF files and download them as STL: free, in batch, and they never leave your device.

3MF → STL: what you should know

3MF is 3D printing's modern format — Bambu Studio, PrusaSlicer and Cura use it natively because it stores units, colors and even print profiles — but the world still speaks STL: online print services, model marketplaces and legacy software keep requiring it. This conversion extracts the 3MF's geometry and delivers it as universal STL.

Every object in the 3MF package is read with its transforms applied and written as a single binary STL, with the same coordinates — no rescaling. As always on ilove3d, the file is processed in your browser and never uploaded.

What's left behind: the metadata that makes 3MF special (multi-material colors, slicer settings, explicit units) doesn't exist in STL. If your final destination is your own modern slicer, keep the 3MF; convert to STL when the recipient demands it.
