Convert GLB to 3MF

GLB → 3MF: what you should know

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

This tool converts your GLB files to 3MF 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 GLB to 3MF loses nothing that matters: what goes in is what comes out, in the format you need.
