3MF to GLB converter
Drop a 3MF file and get a GLB back in seconds. 3MF is zip-packaged, carries units and colour, used mostly for modern slicers like Bambu Studio, PrusaSlicer and OrcaSlicer. GLB is one self-contained file, the usual choice for the web, Godot, three.js, Android AR and general sharing. The conversion runs entirely in your browser, so your file never leaves your device.

What carries over
- 3MF is Z-up, so the model is turned Y-up on import and keeps its orientation in the GLB.
- Units: 3MF is millimetres, stored in the file and GLB is metres by convention. Numbers are copied 1:1, so check the size in the target app.

Questions
- Is my 3MF file uploaded?
- No. The 3MF is parsed and the GLB is written by JavaScript in your browser tab. The file never reaches our servers.
- Will the GLB look the same as the 3MF?
- The geometry is identical. GLB keeps materials and textures too. See the notes above for this exact pair.
- Is there a file size limit?
- Files up to 150 MB open, but very large models depend on your device's memory. Desktop browsers handle big files best.
