This is the format that is used in the OpenGL and Microsoft DirectX development environment. It is used to store bitmap images of user interface environments and textures. It allows you to store information in compressed and uncompressed forms. It is used for texturing game models and storing entire textural arrays to create games and 3D-software applications. DDS is used to develop the latest-generation video game consoles. It makes it possible to compress texture blocks 'on the fly', which increases performance when you run the application.
this is a new format that supports lossless and loss compression quality for images on the Internet. The Google Company developed this format specifically to do work online as quickly and conveniently as possible. The main advantage is that its file size is small compared to other image formats, but similar in image quality.
