The BMP format, also known as the Device Independent Bitmap (DIB) format, was developed by Microsoft to save images that would not be distorted when viewed on different devices. The format

The BMP format begins with a file header, which includes bitmap identifier, file size, width, height, data compression method (optional), color options, and bitmap data starting point. The header is followed by raw pixel image data and optional ICC Color Profile data.

NOTE: Since BMP files are uncompressed, they may be large in size. Therefore, the JPEG and PNG image formats are common alternatives to the BMP format for saving and transferring digital images.
