What is a BMP file?

A BMP file is an image saved in the Bitmap (BMP) raster image format developed by Microsoft. It contains uncompressed image data that supports monochrome and color images at variable color bit depths, along with image metadata. BMP files are commonly used for storing 2D digital photos.

Microsoft developed the BMP format, also known as the Device Independent Bitmap (DIB) format, to save images that would not be distorted when viewed on different devices. The BMP format begins with a file header, including the 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.
