STL to GLTF Converter
Convert embedded triangle geometry from STL to GLTF.
What changes when exporting STL as glTF?
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 glTF result is intended for web graphics and interoperable 3D assets. glTF is a scene-oriented format often used for real-time 3D on the web; this exporter focuses on the supported mesh geometry.
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 GLTF.
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.
