PostScript is Adobe's page description language — a complete programming language for defining printed page content with vector precision, embedded fonts, and device-independent color. PS files contain the instructions that drove professional printing for decades. JPEG (Joint Photographic Experts Group) is the world's most widely used image format, providing excellent lossy compression for photographic and complex visual content. JPEG files are universally supported across every device, browser, and application.
Converting PS to JPEG rasterizes a PostScript page into the most universally compatible image format. This conversion produces an image that can be viewed, shared, and embedded anywhere — from email attachments and web pages to presentations and social media posts.
PostScript files are essentially unviewable outside of specialized software. Most people cannot open a .ps file on their computer without installing Ghostscript or a similar PostScript interpreter. Converting to JPEG creates an image that every person on every device can immediately view. JPEG's efficient compression keeps file sizes manageable for email and web sharing while preserving excellent visual quality.
For archiving PostScript print files, JPEG provides a practical viewing format that can be indexed, searched (with metadata), and browsed in standard image management tools. Digital asset managers, web content systems, and presentation tools all expect image formats — JPEG is the most universally accepted option for photographic-quality PostScript content.
Ghostscript interprets the complete PostScript program — executing all vector drawing operations, text rendering with font hinting, image compositing, and color space conversions. The rendered page is output as a rasterized bitmap at the specified resolution, then encoded to JPEG using DCT (Discrete Cosine Transform) compression. JPEG quality is configurable from 1 (maximum compression, low quality) to 100 (minimal compression, highest quality). Ghostscript handles all PostScript levels (1, 2, 3), EPS files, and DSC-conforming multi-page documents. CMYK PostScript content is converted to sRGB color space for JPEG output.
JPEG output provides excellent visual quality for PostScript content at quality settings of 85-95. The lossy compression introduces minor artifacts — most visible around sharp text edges and high-contrast boundaries. For PostScript files with primarily photographic content or complex gradients, JPEG at quality 90 is nearly indistinguishable from the original rendering. For PostScript files with sharp line art, technical diagrams, or text at small sizes, PNG format preserves edges better than JPEG. CMYK-to-RGB color conversion may shift saturated process colors slightly.
