Files that contain the .pcx file extension store Paintbrush bitmap graphics. This raster image format was developed by Zsoft. The format was one of the original bitmap file formats to be used on the Windows and DOS operating systems.
The PCX file format supports 24-bit color graphics as well as 8-bit grayscale and indexed color images. PCX files are compressed with RLE encoding. A variety of scanning and digital fax applications use the PCX file format to store digital fax copies.
The PCX file format is now somewhat outdated and has been largely replaced by the PNG, GIF and JPEG file formats.
