PNG stands for Portable Network Graphics. its a file image that contains a bitmap of indexed colours under a lossless compression.

commonly used to store graphics for web images. The PNG format was created in response to limitations

with the GIF format, primarily to increase colour support and to provide an image format without a patent license.

PNG images cannot be animated like GIF images. However, the related .MNG format can be animated.

PNG images do not provide CMYK colour support because they are not intended for use with professional graphics.
