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.

No. JPEG's lossy compression blurs the sharp edges and flat color boundaries typical of pixel art. Use PNG or GIF for pixel art PCX files.

Quality 85-90 for photographic PCX content. Quality 92+ for archival-quality conversions. Lower quality settings introduce visible artifacts.

Yes. 1-bit, 4-bit, 8-bit, and 24-bit PCX files are all converted to 24-bit RGB JPEG output.

JPEG compression softens sharp edges by design. Game sprites, pixel art, and icons should be converted to PNG instead, which preserves crisp pixel boundaries.

Significantly smaller. A 1 MB PCX file typically compresses to 50-200 KB JPEG at quality 85. The exact ratio depends on image content and complexity.
