What is a GLB File?

GLB Converter

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.

What is a STL File?

STL Converter

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.
