PCX (PC Paintbrush Exchange) is a legacy bitmap format from the MS-DOS era, while JPEG is the universal photographic compression standard. Converting PCX to JPEG compresses the legacy image data into the most widely compatible compressed format, making it viewable on any modern device. This conversion is useful for PCX files that contain photographic or continuous-tone content, such as scanned photographs from the DOS era or early digital camera output.
JPEG's lossy compression produces small files from PCX source data, which is important when legacy image archives need to be migrated to modern storage systems or published on the web.
PCX is not supported by modern operating systems, web browsers, or most applications. JPEG is universally supported everywhere. Converting PCX to JPEG makes legacy images accessible on any device without specialized software. JPEG's compression also reduces file sizes significantly, which is important for migrating large legacy PCX archives to modern systems.
JPEG is also the expected format for photographic content in modern workflows. PCX scanned photographs, early digital photos, or medical images that need to be incorporated into modern databases, presentations, or web content should be converted to JPEG for compatibility.
The PCX file is decoded (header parsing, RLE decompression, palette application) and the pixel data is compressed using the JPEG DCT algorithm at a configurable quality level (1-100). PCX palette-indexed images are expanded to full RGB before JPEG encoding. Since JPEG does not support indexed color or palettes, the conversion always produces full-color output. ImageMagick handles the PCX decoding, and Sharp performs the JPEG encoding with support for progressive mode and chroma subsampling.
For photographic PCX content (scanned photos, continuous-tone images), JPEG quality 85-90 produces excellent results with significant compression. For PCX pixel art, retro game graphics, and images with sharp edges and flat colors, JPEG compression introduces visible artifacts. These types of images are better served by PNG or GIF conversion.

PCX to JPEG is best for photographic legacy content that needs modern compatibility and compression. For pixel art and flat-color PCX images, use PNG or GIF instead.
