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.

Questions
Is this USDZ to 3MF 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 USDZ 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 USDZ to 3MF?
Textures: texture images are dropped, so uv mapped detail will not travel with the file. Animation: animation tracks are dropped, because the output format stores static geometry only.
Which programs open 3MF files?
PrusaSlicer, Bambu Studio, Cura, Windows 3D Builder and most other tools that work with 3D meshes read .3mf directly.
