What is a GLTF File?

GLTF Converter

glTF (GL Transmission Format) is an open standard for 3D scenes and models developed by the Khronos Group, designed for efficient transmission and loading of 3D content on the web and in 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.
