GLB to STL converter
Convert GLB to STL from supported scene geometry in your browser. Inspect object placement and dimensions; textures, materials and animation are not part of a standard STL mesh.

A GLB to STL converter for mesh geometry
This GLB to STL converter is free to use in the browser. Keep the original GLB when its visual materials or scene data matter, and check that the exported surface represents the object you intend to manufacture. Changing the container cannot turn a texture detail into physical relief.
Prepare GLB geometry for STL export · Use the glTF input tool instead
Check the GLB extension before converting
A filename ending in .gib does not match this tool’s GLB input. The GLB extension is .glb: its middle character is the letter L. Ask the source application for a GLB export if needed. Changing a different file’s extension to .glb does not change its contents or make it convertible.
Processing limits
STEP input: 20 MB. STL, OBJ and 3MF input: 50 MB. Output is limited to 1.2 million triangles. Complex models may need simplification in the source application.
One file at a time. Processing stops after 90 seconds. Files remain in browser memory, and no conversion upload is performed. Replacing a file clears the previous result. Closing the tab releases its working data.
