GLB to STL
Convert GLB and glTF models to STL for 3D printing. Upload a .glb file and download a print-ready .stl for your slicer.
Convert GLB to STL in one step
Upload a GLB or glTF model and get back an STL file ready for your slicer. GLB is the standard for 3D on the web, in AR, and from most AI 3D generators; STL is what 3D printers expect. This converter bridges the two at full fidelity.
How to convert GLB to STL
- Upload your .glb file (or a .gltf with embedded data).
- Run it.
- Download the .stl and open it in Bambu Studio, PrusaSlicer, Cura, or any other slicer.
Features
- Full-fidelity geometry. Converted through Blender, so the mesh comes across unchanged.
- Print-ready output. A standard STL every common slicer opens.
- Nothing to install. Runs in your browser.
- Made for AI-generated models. Print anything you create with Image to 3D Model or Text to 3D Model.
FAQ
How do I convert a GLB file to STL?
Upload the GLB here and run it. You get an STL back in seconds.
What happens to the textures?
STL stores shape only, so textures and colours are dropped. The geometry is kept exactly.
Does it work with .gltf files?
Yes, as long as the .gltf has its data embedded. A .gltf that points to separate .bin or texture files cannot be read on its own, so use a single .glb where you can.
Will the STL print cleanly?
Models made for screens are not always watertight. If your slicer reports errors, run the file through STL Repair first.
