画图是一个简单的图像绘画进程，是微软公司Windows操作系统的预载软件之一。自从发布以来，大部分的Windows操作系统都内置了这个软件。它的外号通常是MS Paint或者Microsoft Paint。这个软件可以打开并查看WMF和EMF文档，打开并保存BMP（24-bit、256色、16色和单色）、JPEG、GIF（不包括透明和动画数据，但Windows 98和更新后的Windows 95可以支持后者）、PNG（不包括阿尔法信道）以及TIFF格式的图像文档。比较旧的小画家版本不支持PNG格式，也只能在使用图像过滤的情况下打开GIF、JPEG、和TIFF文档。另外，新版本不再支持PCX格式，以及其他比较古老的格式（例如RLE）。新版本也不再支持在Windows 3.x中的画笔以及Windows 1和2中的画图所支持的MSP文档格式。

Microsoft Paint is a simple computer graphics program that has been included with all versions of Microsoft Windows. The program mainly 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, although the Windows 98 version, a Windows 95 upgrade, and the Windows NT4 version did support the latter), PNG (without alpha channel), and single-page TIFF. The program can be in color mode or two-color black-and-white, but there is no grayscale mode. For its simplicity, it rapidly became one of the most used applications in the early versions of Windows—introducing many to painting on a computer for the first time—and is still widely used for very simple image manipulation tasks.
