How to convert GLB to STL
- Add your .GLB file - drop it in the box above or click to browse.
- Convert it to .STL in a few seconds.
- Download your new .STL file.
What to expect
- STL stores only triangle geometry - all materials, textures, PBR properties, and colors from the
.glbare dropped. - Animation and skeletal rigs are not exported; the
.stlcaptures the mesh at its current pose (frame 0 by default in Blender). - GLB uses meter units while most slicers read
.stlin millimeters - a 1.8 m model will arrive as 1.8 mm, so scale by 1000 before exporting.
Frequently asked questions
Is anything lost when converting GLB to STL?
Yes - STL holds only the triangle mesh, so all textures, materials, colors, PBR data, and animation from the
.glb are discarded. If you need color in a print, consider .3mf or OBJ+MTL instead.Why does my model print at the wrong size?
GLB stores geometry in meters while most slicers read
.stl in millimeters, so a 1.8 m figure imports as 1.8 mm. Multiply all dimensions by 1000 in Blender (S > 1000 > Enter) or use your slicer's scale tool before printing.Do I need to install anything to use the converter on this page?
No - the converter above is free; just upload your
.glb and download the result.What if my GLB fails to import into Blender?
Some
.glb files use Draco mesh compression; make sure the glTF 2.0 importer add-on is enabled in Blender Preferences > Add-ons, as Draco support requires it.
