The BMP file format is a two dimensional image file format popular on Microsoft Windows operating systems. Data is stored in the BMP file in a raster format with pixels being represented using various colour depths ranging from monocrome 1-bit per pixel (bpp) to full color 24-bits per pixel.

The format can also contain an image alpha channel which is typically 8 bits per pixel in size and is used to describe image transparency. BMP files can also optionally be compressed using a lossless compression algorithm meaning smaller files with no loss of image quality.

The PNG graphics file format is a commonly used format for storing 2D images which can be highly compressed by the use a palette if the image has a sufficiently low number of colors (256 colors in general). The PNG file is then further compressed using the DEFLATE compression algorithm to ensure small file sizes that are fast to download.

PNG files are seen as the logical successor to the GIF image file format and was devised in the mid-1990's as a superior format to GIF. PNG files are generally used for company logos, icons and other non-photographic image content. Saving a digital photo in the PNG format will create a much larger file than an equivalent JPG image hence the PNG format being unsuitable for most digital photo content.
