Convert PCX to PNG — Free Online Converter

PCX (PC Paintbrush Exchange) is a legacy DOS-era bitmap format with RLE compression, while PNG (Portable Network Graphics) is the modern standard for lossless raster images. Converting PCX to PNG is the recommended modernization path for legacy PCX files because PNG provides lossless quality, smaller file sizes than BMP, full transparency support, and universal compatibility across all modern platforms.

PNG is effectively the modern successor to PCX's role as a lossless bitmap format. Every feature PCX provided (lossless compression, palette support, multiple color depths) is available in PNG with better compression, wider compatibility, and additional capabilities like alpha transparency.

PCX is not supported by modern operating systems, web browsers, or most applications. PNG is supported everywhere -- every browser, every OS, every image editor, every CMS platform. Converting PCX to PNG provides the most natural modernization path because PNG is the closest modern equivalent in terms of lossless quality and compression.

PNG's DEFLATE compression is significantly more effective than PCX's RLE compression, especially for complex images. Legacy PCX files converted to PNG are typically the same size or smaller, while being accessible to billions of modern devices that cannot open PCX format.
