The Khronos Group developed GLB files as a format for storing complex 3D models. The format was first introduced in 2015 and aimed to create a format that could be easily adopted by third-party developers. Subsequent versions have followed this initial release, adding more complex features.
Support for GLB files is growing and has found support in many modern 3D model editors, such as Blender, which currently supports importing from and exporting to the GLB format.
Mesh Geometry
At the heart of the GLB format is its ability to store 3D geometric mesh data, which comprises vertices, faces, normals (both face and vertex normals), and texture coordinates. The data is saved in a compact binary format, ensuring GLB files are compact and easy to distribute.
GLB Converter Capabilities
As materials containing texture and color information are both supported by the GLB format, our tool will do its best to include these materials, including any texture files, in the converted file.

The Khronos Group created the DAE file, a 3D model file format. The format is an XML text-based format, storing the 3D model information in a standardized XML structure, ensuring it is easy to add additional features without introducing compatibility issues.
Many 3D editing applications support the importing and exporting of DAE files, including the popular 3D editor Blender.
Mesh Geometry
DAE files support mesh geometry along with various types of surface definitions, from simple triangles to full polygon meshes. It has support for face and vertex normals and texture coordinates too. Mesh elements defined within the XML structure can be shared between multiple 3D objects within the final rendered scene.
DAE Converter Capabilities
As materials containing color information is supported by the GLB and DAE formats, our tool will do its best to include this in the converted DAE file.
