How to reduce PDF file size in Linux

Using a single line of GhostScript command on my Ubuntu’s terminal, I was able to reduce the size of a  PDF file from 6 MB to approximately 1 MB:

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

You can also use the following parameters for -dPDFSETTINGS instead of /screen:

  • /screen – Lowest quality, lowest size
  • /ebook – Moderate quality
  • /printer – Good quality
  • /prepress – Best quality, highest size
