MS Paint is a basic raster graphics editor that has been included with every version of Microsoft Windows. The program supports opening and saving files in various formats, including Windows Bitmap (BMP), JPEG, GIF, PNG, and single-page TIFF. It offers functionality in both full-color mode and two-color black-and-white mode, though it does not support grayscale.
Due to its straightforward interface and availability as a built-in application, MS Paint quickly became one of the most widely used programs in the early days of Windows. It introduced many users to digital painting and image creation for the first time. Even today, it remains a popular choice for simple image editing tasks.
