3MF to PLY Converter
Drop a .3mf file below and get a .ply back. The conversion happens inside this page using WebAssembly, so nothing is uploaded to a server and there is no queue to wait in.

How to convert 3MF to PLY
- 1Add your 3MF fileDrop the .3mf file into the box, or pick it from disk. Multiple files are converted one after another.
- 2Pick PLY as the outputPLY is already selected on this page. Adjust scale, up axis or triangle budget if the target application is picky.
- 3Download the resultThe .ply file is written locally and appears as a download button next to your file.
About 3MF
3MF is a zipped XML package that fixes what STL never had: real units, colours, materials, multiple objects and print metadata. Every current slicer reads it and it is the default in Bambu Studio and PrusaSlicer.

About PLY
PLY was designed for range scanner output, so it stores arbitrary per vertex properties such as colour, confidence and intensity. Both an ASCII and a compact binary variant exist and both are widely supported.

Questions
Is this 3MF to PLY converter free?
Yes. There is no account, no daily quota and no watermark. The tool is a static web page and the work is done by your own CPU, so there are no server costs to pass on.
Are my files uploaded anywhere?
No. MeshFormat loads a WebAssembly build of the geometry kernels into your browser and reads the file locally. You can open the network tab and confirm that nothing leaves the page, or disconnect after the page has loaded and keep converting.
How large can a 3MF file be?
The practical limit is your available memory rather than an arbitrary cap. Models up to a few hundred megabytes work on a normal laptop; very dense scans convert faster if you lower the triangle budget in the options.
What is lost when converting 3MF to PLY?
Materials: material definitions are dropped, so the model arrives with a single neutral surface. Scene hierarchy: the scene tree is flattened, so parts arrive as a single level list rather than nested groups.
Which programs open PLY files?
MeshLab, CloudCompare, Blender, RealityCapture and most other tools that work with 3D meshes read .ply directly.
