A JPG file is a flat, two-dimensional image file format created for the purpose of storing photographic images in a highly efficient digital format. JPG files are widely used and supported by all image editing applications and can be opened on most devices with no additional image viewing software.
For many years, image file formats consumed large amounts of storage space while not offering 16.7 million full-color capabilities. JPG aimed to solve this by offering a full-color solution combined with lossy compression techniques to allow high-resolution photographs to be stored using very little storage space and bandwidth.
Uses
The JPG format is ideally suited to storing full-color photographic images. Due to the lossy compression it employs, it is not suitable for storing high-fidelity items such as logos and any image that contains transparency.

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.
