STL to GLB Converter
Convert embedded triangle geometry from STL to GLB.
What changes when exporting STL as GLB?
An STL source is useful for 3D printing and simple mesh export. STL stores a triangle surface without UV textures or scene hierarchy; it is widely used for 3D printing.
The GLB result is intended for distributing 3D mesh assets in a single binary file. GLB is useful for moving self-contained 3D assets between compatible apps; this exporter does not reconstruct unsupported materials or animations.
Before you download
- The converter operates on supported mesh geometry. Do not assume it preserves original materials, UV textures, skeletal animation or full scene hierarchy.
- Check mesh units, face orientation and scale in your target application, especially before printing or importing into a game engine.

About this tool
Convert embedded triangle geometry from STL to GLB.
Geometry only. Textures, materials, rigging and animation are not preserved; complex polygons are triangulated. glTF imports require embedded (not external) buffers and non-interleaved triangle accessors.
