Convert PS to BMP — Free Online Converter

PostScript (PS) is Adobe's page description language, a Turing-complete programming language designed to describe the appearance of printed pages with mathematical precision. PostScript files contain vector graphics, text with embedded fonts, and rasterized images, all described through a stack-based programming syntax. PS was the dominant language for professional printing from the 1980s through the 2000s before PDF largely replaced it. BMP (Bitmap Image) is Windows' native uncompressed raster image format, storing pixel data without any lossy compression.

Converting PS to BMP rasterizes a PostScript page description into an uncompressed bitmap image. This conversion is needed when PostScript artwork, technical drawings, or print-ready pages need to be used in contexts that require raster image files — image editors, web pages, presentations, or applications that cannot interpret PostScript commands.

PostScript files cannot be viewed by most modern applications — they require a PostScript interpreter (like Ghostscript) or a professional prepress RIP. Converting PS to BMP creates a universally viewable image that any computer, phone, or web browser can display. BMP's uncompressed nature means zero quality loss from the rasterization, preserving every pixel of the rendered output.

Legacy print archives often contain thousands of PS files from prepress workflows of the 1990s and 2000s. These archives need to be migrated to modern image formats for viewing, cataloging, and integration into digital asset management systems. BMP serves as a lossless intermediate format that can be further converted to PNG, JPEG, or TIFF as needed.
