GLB to STL
- Kept. shape.
- Dropped. colours, textures, bones and animation.
- Size. Written in the unit you pick, millimetres for printing.
- Up axis. STL stands on Z. The page turns the model for you.
The two types
- GLB. GLB is glTF in one file: shape, materials, textures, bones and animation. Web viewers, AR, Unity, Godot and Blender all read it. Opened by Blender, Unity, Godot, Unreal, Windows 3D Viewer and any web browser with a viewer page.
- STL. STL describes a surface as triangles and nothing else: no colour, no units. Slicers read its numbers as millimetres. Opened by Cura, PrusaSlicer, Bambu Studio, Blender, MeshLab and Fusion 360.
Questions
How do I convert GLB to STL?
Drop the GLB file on this page, check the size under What’s inside, and press Download STL. It runs in your browser, so there is no upload and no wait.
What does GLB to STL keep?
STL keeps the shape. It has no place for colours, textures, bones and animation, so those are dropped.
What size will the STL be?
STL has no units, and slicers read its numbers as millimetres. The page writes millimetres, so a 40 mm part from GLB arrives 40 mm long. If the size looks off, change Write as under What’s inside.
Why does my STL lie on its side in the slicer?
GLB stands on its Y axis and slicers use Z. The Z up box, on by default, turns the model so it sits flat on the plate. Untick it for a program that expects Y up.
Will the STL print?
What’s inside says whether the surface is closed, which slicers need. If it is open, repair it in your slicer, Meshmixer or Blender first.
Is my file uploaded?
No. The file is opened and converted in your browser, and it stays on your device.
Is it free?
Yes. There is no account, no watermark and no limit on files.
