PCX (PC Paintbrush Exchange) is one of the earliest PC bitmap formats, created by ZSoft for their PC Paintbrush program in the MS-DOS era. PCX uses simple RLE (Run-Length Encoding) compression and supports 1-bit monochrome through 24-bit true color. Despite being largely superseded by modern formats, PCX files still appear in legacy software archives, retro gaming communities, and older industrial systems that were built around this format.
BMP (Bitmap) is Windows' native uncompressed raster format with universal compatibility. Converting PCX to BMP transforms these legacy files into a format that every modern operating system, image viewer, and application can open without any issues. It is the most straightforward modernization path for PCX files.
Modern operating systems and applications have dropped PCX support. Windows Photo Viewer, macOS Preview, web browsers, and most current image editors cannot open PCX files. Converting to BMP provides immediate accessibility on any modern system. BMP's simplicity and universal support make it the closest modern equivalent to PCX's role as a basic bitmap format.
PCX files are also encountered in data recovery and digital archaeology scenarios. When extracting assets from legacy software, DOS game archives, or vintage clip art collections, converting PCX to BMP is the first step to making these images usable in modern workflows.
The PCX file is decoded by parsing its 128-byte header (manufacturer, version, encoding, bits per pixel, palette type) and decompressing the RLE-encoded scanline data. PCX supports 1-bit monochrome, 4-bit (16 colors), 8-bit (256 colors with VGA palette), and 24-bit (true color) modes. The 256-color palette in 8-bit PCX files is stored in the final 769 bytes of the file. Indexed color images are expanded to full RGB during decoding. The pixel data is written as a Windows BMP v3 file with 24-bit color depth. ImageMagick handles the PCX format decoding.
No quality loss occurs. PCX and BMP both store pixel data at full fidelity. The RLE decompression is lossless, and the BMP output is a pixel-perfect representation of the PCX image. Color palette mapping for 8-bit PCX files is exact -- each palette index maps to its defined RGB color value.

PCX to BMP is the simplest way to make legacy PCX files accessible on modern systems. The conversion is lossless and produces universally readable output.
