BMP is a family of simple raster graphics image file format designed to store bitmap digital images independently of a display device. BMP was originally and is primarily used on Microsoft Windows and OS/2 operating systems. The format is sometimes known as Device-Independent Bitmap (DIB), since, when loaded into memory using Windows software, the image is held as a DIB structure.

As of November 2012, there have been 7 versions (similar but not identical of the Windows Bitmap format, identified by PRONOM as: fmt/114 (version 1.0); fmt/115 (version 2.0); fmt/116 (version 3.0); fmt/117 (version 3.0 NT); fmt/118 (version 4.0); fmt/119 (version 5.0); x-fmt/270 (OS/2 Bitmap version 2.0. See OS/2 BMP). No MIME type has been officially registered. Strings found in practice are: image/bmp; image/x-bmp; image/x-ms-bmp

Identification

The standard file extension is .bmp. Reportedly, .dib and .rle have occasionally been used.

BMP files start with bytes 'B' 'M' ?? ?? 00 00 00 00.
