What is BMP?
BMP (Bitmap) is a raster image format originating from Microsoft Windows. A .bmp stores pixels in a grid with optional color tables and multiple headers (e.g., BITMAPFILEHEADER and BITMAPINFOHEADER). It typically uses no compression, though simple RLE is supported, so files can be large compared with PNG or JPEG. BMP supports a wide range of color depths—from 1-bit monochrome to 24-bit true color and 32-bit with alpha via bitfields—making it suitable for pixel-accurate graphics, icons, and screenshots. Because it is device-independent and straightforward to parse, BMP is widely supported by editors like Paint, Photoshop, GIMP, and Preview. However, it lacks modern features such as advanced compression and extensive metadata. Many users convert BMP to PNG for smaller size and lossless quality.
