What is the full form of PNG?
The full form of PNG is Portable Network Graphics. PNG was developed as an open system to replace GIF because one corporation owned the patent for GIF and no one else chose to pay license fees. It also enables a full variety of colours and higher compression.
PNG is a format for the computer storage of bitmapped or raster images. It is often regarded as a successor of GIF images, utilizes the less compression method to save images such as GIF files but without concerns with copyright. It includes an indexed colour bitmap so that it is also named a bitmapped image.
