3MF lives in the printing world; GLB lives on the web. Convert one to the other in this tab — free, no signup, nothing uploaded — and your printable model becomes something you can put in a link.
Three steps, one page, no account. The whole conversion is a local operation — the slowest part is you finding the file.
Drag the file onto the box above. It is read straight off your disk with the browser's File API — no upload, and no progress bar to a server.
The file is parsed, every mesh is baked into world space, and the result is written out in the target format. Your CPU does the work, so a client's unreleased model never leaves the room.
Save the converted file and open it wherever you were headed. Nothing is watermarked and nothing expires.
They solve different problems, which is exactly why one direction of this conversion costs you something and the other does not.
3MF is the modern replacement for STL, backed by the printing industry. It is a zipped XML package that states its own units, keeps shared vertices intact and has room for colour and print settings — which is why Bambu Studio, PrusaSlicer and Cura all prefer it.
GLB is the binary flavour of glTF — one file carrying geometry, UV coordinates, materials, textures and a scene graph together. It is what the web, Blender, Unity, Unreal and Three.js all read natively, and it is what this site's generator hands you.
Every conversion is a trade. Any tool that tells you otherwise is lying to you, so here is the exact ledger before you commit.
GLB is the format to keep. It holds geometry and texture in one file and every modern engine reads it, which is why the generator on this page outputs it. Convert onwards whenever a slicer or an older pipeline needs something else.
Reach for this when a model that was built for a printer now needs an audience. Slicer software is the only thing that reads 3MF, and a browser is not slicer software.
The mesh comes across intact, including its shared vertices; slicer-specific data such as supports and print profiles does not, because none of it is geometry. Check the mesh in the viewer to see exactly what you have.
You do not have to go back to the home page. Type a prompt or drop an image, and take the .glb — free, anonymous, no watermark.
No. A 3MF written by a slicer can carry supports, profiles and plate layouts; the converter reads the geometry and writes that into the GLB. What you get is the model, not the print job.
Yes — that is the point of the conversion. Every modern browser-based viewer reads GLB, including the free viewer on this site, so a converted model can be linked, embedded or previewed in AR without any software.
Same converter, same rules: free, in your browser, no signup.
3D AI Studio generates the .glb too — free, anonymous, no watermark.
No signup, no upload, no watermark — and the converter does not care how big the file is.
