brew install ghostscript
# If you’re using Linux you can install ghostscript from aptitude, or your package manager of choice [2].

# Now, you can use ghostscript to compress your PDF file for the web:

gs -sDEVICE=pdfwrite -dNOPAUSE -dQUIET -dBATCH -dPDFSETTINGS=/screen -dCompatibilityLevel=1.4 -sOutputFile=output.pdf input.pdf

# That’s not exactly a memorable command, so I’ve made a function that you can add to your ~/.bash_profile to allow you to easily compress PDF files from your terminal:

-------------------------------
# Usage: compresspdf [input file] [output file] [screen*|ebook|printer|prepress]
compresspdf() {
    gs -sDEVICE=pdfwrite -dNOPAUSE -dQUIET -dBATCH -dPDFSETTINGS=/${3:-"screen"} -dCompatibilityLevel=1.4 -sOutputFile="$2" "$1"
}
-------------------------------

Now you can simply run the following command:

compresspdf "Massive.pdf" "Small.pdf"
