The full form of PNG is a "Portable Network Graphics". PNG was developed as an open system to replace GIF because one company owned the patent for GIF and no one else chose to pay royalties. It also allows full color gamut and higher compression.
PNG is a format for computer storage of bitmap or raster images. Often considered the successor to GIF images, it uses a smaller compression method to store images like GIF files, but without copyright concerns. It contains an indexed color bitmap, so it is also called a bitmap image.
History
The PNG format was established in early 1995. GIF contains only 256 colors, and this limitation of GIF contributes to the development of PNG and is the main reason for its implementation.
