The Stereolithography (STL) format stores surface geometry as triangulated mesh data. It is the universal standard for 3D printing but lacks support for colors, textures, and materials.
GLB is the binary version of glTF, packaging all assets (meshes, textures, animations) into a single file. It is widely used for web-based 3D, AR/VR, and real-time rendering applications.
Converting STL to GLB enables compatibility with web 3D viewers, AR/VR, and compact model distribution. Upload your Stereolithography file and get a GL Binary file ready for download in seconds.
