What is BMP file?

The .bmp stands for Windows bitmap image file type. Although this format was first introduced by Microsoft, nowadays all the major operating systems and image software support this image format. The structure of the file consists of the proprietary windows bitmap data structure which stores the pixel information to represent the image file.

The image format uses a simple RLE compression technique for Image storage which is fairly inefficient for large and complex image data. This is one of the most trivial Image formats and currently is in its 4th updated version. As its compression ratio is less, it is used less often than other popular formats like PNG and JPEG.
