PostScript defines page content through vector programming commands with mathematical precision — every curve, line, character, and image is described by coordinates and equations. PNG (Portable Network Graphics) is a lossless raster image format supporting full 24-bit color, alpha transparency, and efficient DEFLATE compression. PNG is the standard format for screenshots, UI graphics, and any image where pixel-perfect quality matters.
Converting PS to PNG rasterizes PostScript page descriptions into lossless images with perfect edge clarity, no compression artifacts, and optional transparency. This is the preferred raster conversion for PostScript content containing text, line art, and technical diagrams where JPEG's lossy compression would degrade quality.
PostScript files need specialized software to view, but PNG images are universally viewable across every device and application. PNG's lossless compression preserves the sharpness of PostScript's vector rendering — text edges are crisp, lines are clean, and colors are exact. For PostScript content that is predominantly text, diagrams, or line art, PNG provides noticeably better quality than JPEG.
PNG's transparency support is also valuable for PostScript artwork. Logos, illustrations, and graphic elements from PostScript files can be converted to PNG with transparent backgrounds, ready for layering onto web pages, presentations, and design compositions without white rectangle artifacts.
Ghostscript interprets the PostScript program, executing all vector operations, text rendering, and image compositing at the specified resolution. The rendered bitmap is output in PNG format using DEFLATE lossless compression. PNG supports 24-bit RGB color (16.7 million colors), 32-bit RGBA (with alpha transparency), and 48-bit deep color. For PostScript pages with no background (or a removed background), the PNG output includes an alpha channel for true transparency. Ghostscript handles all PostScript language levels, font types, color spaces, and imaging operators. Resolution is configurable from 72 DPI (screen) to 1200+ DPI (high-quality print).
PNG output is pixel-perfect — every detail of the Ghostscript rendering is preserved without any compression artifacts. Text edges are razor-sharp, lines are clean, and colors are exact. This makes PNG the best raster format for PostScript content containing text, technical drawings, and flat-color artwork. The trade-off is file size: PNG files are significantly larger than JPEG (typically 3-10x) for the same image dimensions. For photographic PostScript content where file size matters and lossless quality is not critical, JPEG may be more practical.
