A system for converting a page description file to a composite representation thereof for fast web viewing, the system includes a conversion engine configured to convert a page of graphics into an aggregate file, a rendering utility for rendering the aggregate file, a comparison engine for comparing the image-only bitmap and the aggregate bitmap to create a foreground bitmap file which is displayed on a Web browser and a delivery engine for delivering the foreground bitmap file and the background raster file to a Web browser by creating HTML code which superimposes the foreground bitmap file and the background raster file, thereby providing a small sized, high quality image and text composite representation of the page description file.
