Convert 3D files between STL, OBJ, 3MF, PLY and GLB. Convert one file or a whole folder at once, and resize on the way. Everything runs in your browser, so your files are never uploaded.
3MF is the native format of Bambu Studio, PrusaSlicer and OrcaSlicer. It stores real millimeter units, so a model always opens at the right size.
It is also compressed, so a 3MF is usually much smaller than the same model as STL.
The model is saved sitting on the build plate, so it opens flat and ready to slice.
The 3MF holds the model only. Add your printer, filament and print settings in your slicer as usual.
Shared vertices are stored once instead of three times, and the file is zipped. Large, detailed models often shrink to a fraction of their STL size.
Yes. The file uses the standard 3MF format, which Bambu Studio, PrusaSlicer, OrcaSlicer, Cura and Windows 3D apps all open.
Usually yes. 3MF stores each corner of the model once and compresses the file, so it is often much smaller than a binary STL.
Not yet. Each STL is converted into its own 3MF. You can open them together in your slicer and save one project from there.
No. It contains the model only, so you choose your printer, filament and settings in your slicer.
No. Your files are converted by your browser on your own device and never sent to our server. That also makes it fast, even for large files.
