Convert GLB / glTF to STL
Convert a 3D GLB or glTF model to STL format for 3D printing or CAD, directly in your browser.
Drag and drop a .glb or .gltf file here, or click to browse.
How it works
Have a 3D model in GLB/glTF (downloaded, AI-generated, etc.) and want to 3D print it? Slicers usually expect an STL file. Import your model, run the conversion, and get an STL ready to open in your slicing software.
Binary or text (ASCII)?
Binary STL is much more compact and loads faster in most software: choose it unless you specifically need a plain-text readable file.
Are colors and textures preserved?
No: the STL format only describes geometry (triangles), without color, texture, or material. This information from the original GLB/glTF is lost during conversion.
100% local processing: the conversion happens entirely in your browser; your model is never sent to a server.
