* How to  reduce the size of a pdf file

** Use libreoffice

Open the file with libreoffice. Then export it as pdf with low resolution to reduce
the file size.

** Use ghostscript

You can use the command ~gs~ to call ghostscript. ghostscript is a PostScript, and PDF language interpreter and previewer.

Let's try to reduce the size of the "cvjb.pdf" and then write it as "output.pdf"


#+begin_example sh
  gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/screen -dNOPAUSE -dQUIET -dBATCH -sOutputFile=output.pdf cvjb.pdf
#+end_example
