Convert VRML to 3MF
Convert a VRML file to 3MF in your browser. Free, no upload, no sign-up.
Convert VRML files to 3MF directly in your browser. The converter parses the VRML mesh, rebuilds it in memory and writes it out as 3MF, keeping every triangle. Nothing is uploaded, there is no file size limit beyond your computer's memory, and the result downloads instantly. 3MF records the unit and can hold several objects with colors, so the model opens in the slicer at the right size without guessing.
How to convert VRML to 3MF
- 1Drop your VRML file
Drag a .wrl file onto the box above or click to choose one. VRML 2.0 (VRML97) files are read; VRML 1.0 is not supported.
- 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 3MF
Adjust the export options if needed and click download. The exported file declares millimeters as its unit and contains the mesh as a single object.
What is a VRML file?
VRML (.wrl) is a 1990s text format for 3D scenes on the web. It still shows up as the export format of older CAD systems and as the input format some full-color 3D printing services require, because it carries per-face colors.
Commonly used by: legacy CAD exports, full-color 3D printing services, KiCad 3D models

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
