Convert STL to GLTF online
Use this STL to GLTF converter to turn STL files into GLTF right in your browser — ideal for web 3D, AR/VR scenes and engine import.
When should you convert STL to GLTF?
- When you need it for web 3D
- When you need it for AR/VR scenes
- To open your files in apps that prefer GLTF
- To share GLTF files more easily
What happens to your file
The STL mesh is loaded and re-exported as GLTF. Straight geometry conversions go through trimesh; when textures and materials need to survive the trip, the job is handed to Blender instead.
Settings this conversion runs with
| Loader | trimesh |
|---|---|
| Textured path | Blender (GLB, glTF, OBJ) |
| Materials | Preserved |
What changes
- GLTF normally stores its materials and textures in separate sidecar files. When the model is textured, the export is packaged as a ZIP so those files stay with the mesh instead of arriving alone and broken.
