Converting glTF Binary (GLB) to STL (stereolithography)
GLB files pack geometry, PBR materials, textures and even animation into a single binary file — perfect for the web and AR, but most 3D printers and slicers can't read them. Converting GLB to STL extracts the raw mesh so you can slice and print it.
What's kept and what's dropped
STL stores pure triangle geometry, so your mesh shape and surface detail come across exactly. Colors, textures, materials and animation are dropped — STL has no concept of them.

GLB to STL — FAQ
- Is this GLB to STL converter free?
- Yes — it's completely free, with no sign-up and no file limits. Convert as many GLB files as you like.
- Do my files get uploaded to a server?
- No. The conversion runs entirely in your browser, so your GLB never leaves your device. Even confidential or client models stay private.
- Are colors and textures kept in the STL?
- No. STL is a geometry-only format with no color or texture data. If you need color, convert to OBJ or keep the original GLB for display and AR.
- Is the STL ready for 3D printing?
- The geometry is preserved faithfully. Before printing, check the mesh is watertight (manifold) in your slicer — or use Sculptor's AI generator, which can output print-ready STL directly.
