Reduce PDF file size

We can use ghostscript or ps2pdf:

 

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

ps2pdf -dPDFSETTINGS=/screen input.pdf output.pdf

 

Ghostscript should produce more compatible output.pdf by running twice:

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