Convert 3MF to PLY
Convert a 3MF file to PLY in your browser. Free, no upload, no sign-up.
Convert 3MF files to PLY directly in your browser. The converter parses the 3MF mesh, rebuilds it in memory and writes it out as PLY, keeping every triangle. Nothing is uploaded, there is no file size limit beyond your computer's memory, and the result downloads instantly. PLY preserves per-vertex colors from scans and is the native format of MeshLab and most scanning pipelines.
How to convert 3MF to PLY
- 1Drop your 3MF file
Drag a .3mf file onto the box above or click to choose one. Slicer project files (.3mf from Bambu Studio or PrusaSlicer) are supported; embedded print settings are ignored, geometry and colors are read.
- 2Check the preview
The model renders in 3D so you can confirm it loaded correctly. Dimensions, volume and triangle count are shown next to it; open edges are flagged if the mesh is not watertight.
- 3Download the PLY
Adjust the export options if needed and click download. Per-vertex colors are kept when the source has them; textures are not.
What is a 3MF file?
3MF is the modern replacement for STL, published by the 3MF Consortium (Microsoft, Autodesk, HP, Prusa and others). It is a ZIP archive containing XML that stores units, colors, materials, multiple objects and print settings. Slicers such as Bambu Studio and PrusaSlicer use it as their project format.
Commonly used by: Bambu Studio, PrusaSlicer, Cura, Windows 3D Builder, Fusion 360

What is a PLY file?
PLY was designed at Stanford to store 3D scanner output. It supports per-vertex colors and arbitrary custom properties, in either ASCII or binary encoding, which is why scanning and photogrammetry software prefers it over STL.
Commonly used by: 3D scanners, photogrammetry (Meshroom, RealityCapture), MeshLab, research tools
