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.
This format was used to store bitmap and vector images natively on Macintosh computers. It was used for laying out and sharing images between programs. It used JPEG compression algorithms and RLE encoding. Today, the PICT format is used in the Windows environment with the PCT extension.
