Cpdfsqueeze is a lossless compressor for PDF files, which works by rearranging and coalescing content within the file. Very fast!
Pdfsizeopt is a program for converting large PDF files to small ones. If the input PDF has many images or large images, pdfsizeopt can be very slow. Pdfsizeopt can use the following external tools to make images in embedded PDF files smaller: sam2p, jbig2, pngout.
Ghostscript is an interpreter for the PostScript language and PDF files. It has been under active development for over 30 years and has been ported to several different systems during this time. Ghostscript consists of a PostScript interpreter layer and a graphics library.
