Convert 3MF to GLB

3MF → GLB: what you should know

3MF is STL's modern successor for 3D printing: meshes with units, colors and print metadata. It's used mostly in modern 3D printing (PrusaSlicer, Bambu Studio, Windows 3D), and it stores geometry with units, colors, materials and metadata. GLB, on the other hand, is the binary flavor of glTF, the modern standard for 3D on the web: a single file with everything inside — the format expected by the web (Three.js, model-viewer), AR, games, online stores, Sketchfab.

This tool converts your 3MF files to GLB right in the browser: no queue, no artificial size limit and, above all, your file is never uploaded to any server. Geometry is preserved with the exact coordinates and scale of the original — important if the model is going to be printed or measured.

Converting 3MF to GLB loses nothing that matters: what goes in is what comes out, in the format you need.
