3MF to PLY converter
Drop a 3MF file and get a PLY back in seconds. 3MF is zip-packaged, carries units and colour, used mostly for modern slicers like Bambu Studio, PrusaSlicer and OrcaSlicer. PLY is stores vertex colours and point clouds, the usual choice for 3D scans, point clouds and research tools like MeshLab and CloudCompare. The conversion runs entirely in your browser, so your file never leaves your device.

How to use the 3mf to ply converter
- 1Choose your 3MF fileDrag it onto the panel or click to browse. It's read locally and never uploaded.
- 2Check the previewOrbit the model and check the triangle count, size and materials before converting.
- 3Download the PLYExport a PLY with one click. Downloads are included with every plan.
What carries over
- The PLY is written Z-up, which is what slicers and scan tools expect.
- 3MF is Z-up, so the model is turned Y-up on import and keeps its orientation in the PLY.
- Units: 3MF is millimetres, stored in the file and PLY is unitless. 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 PLY is written by JavaScript in your browser tab. The file never reaches our servers.
- Will the PLY look the same as the 3MF?
- The geometry is identical. PLY holds per-vertex colour, so surface appearance changes. 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.
