Bitmap image Reference

A .bmp file contains a raster image in the BMP format of Windows. The pixels are stored without compression in most files, thus the files are large. The format is simple, and every image tool can read it. Windows uses bitmaps internally for many graphics operations. PNG and JPEG replaced BMP for storage and the web.

A file extension is only a part of the file name. It does not give a guarantee about the format or the content of a file. But on Windows, the extension selects the program that opens the file.
