Choose your GLB file
Select GLB from your device. The file is processed locally.
ON YOUR DEVICE
GLB to STL
Convert GLB models to STL on your device. Preview the mesh, then check the exported model.
Choose a 3D model
GLB, glTF, OBJ, STL or PLY · Device-dependent capacity
Three simple steps
Prepare STL output
STL contains triangle geometry only. Materials, textures, scene hierarchy and animation are not retained.
Save and check your STL file
Check scale and orientation in the destination application. STL and OBJ files do not reliably declare units.
Common questions
What changes when I convert GLB to STL?
GLB packages supported scene data into one binary glTF file. Unsupported extensions may not import. STL contains triangle geometry only. Materials, textures, scene hierarchy and animation are not retained. Check scale and orientation in the destination application. STL and OBJ files do not reliably declare units.
Will the STL file be smaller?
Not necessarily. STL contains triangle geometry only. Materials, textures, scene hierarchy and animation are not retained. Size depends on the source and settings. Compare the exported file and inspect its geometry.
Which GLB files work here?
GLB packages supported scene data into one binary glTF file. Unsupported extensions may not import. Only mesh models are supported, not CAD solids or every compressed glTF extension.
Is there a size cap for GLB to STL?
There is no fixed file-size quota. Process one main file at a time. Your device memory and browser determine practical capacity. Large selections show a warning that you can continue past.
