Microsoft Paint

Paint is a simple raster graphics editor by Microsoft. Paint (formerly Paintbrush) is a simple, ultra-basic graphics painting program that is included with almost all versions of Microsoft Windows. It opens and saves files as Windows bitmap (24-bit, 256 color, 16 color, and monochrome, all with the .bmp extension), JPEG, GIF (without animation or transparency), PNG (without alpha channel), and TIFF (without the multiple pages).
