What is PNG?
PNG (Portable Network Graphics) is a raster graphics file format that supports lossless data compression. PNG was developed as an improved, non-patented replacement for Graphics Interchange Format (GIF). PNG supports palette-based images, grayscale images, and full-color non-palette-based RGB or RGBA images.
