BMP (Bitmap) is a raster image file format for storing digital images that represent them as a grid of pixels, with each pixel assigned a color value. Microsoft developed the format for Windows, and it is known for being uncompressed and high-quality but also for creating large file sizes. The .BMP file extension indicates this bitmap format, which is used to store simple, device-independent graphics for various platforms, including Windows and OS/2.

Key Characteristics of BMP

Bitmap Graphics: BMP files store images as a rectangular array of pixels, where each pixel's color is defined.

Uncompressed: BMP files do not typically use compression, which results in larger file sizes compared to compressed formats like JPEG or PNG.

Device-Independent: The format was designed to display images independently of the specific display device, ensuring consistent resolution.

File Extension: Files using this format are usually identified by the .BMP extension.

Color Depth Support: BMP files support various color depths, from 1-bit monochrome to 24-bit true color (16.7 million colors), but they do not support transparency (alpha channels).
