Comprimir PDF

Con ImageMagick se puede comprimir un PDF para que manteniendo la calidad tenga un peso menor.

convert <pdf-origen> -compress Zip <nuevo-pdf-comprimido>

GhostScript

sudo apt install ghostscript
INGS=/prepress -dNOPAUSE -dQUIET -dBATCH -sOutputFile=compressed_PDF_file.pdf input_PDF_file.pdf

In the above command, you should add the correct path of the input and out PDF file.

The command looks scary and confusing. I advise copying and pasting most of it. What you need to know is the dPDFSETTINGS parameter. This is what determines the compression level and thus the quality of your compressed PDF file. dPDFSETTINGS Description

/prepress   # (default)	Higher quality output (300 dpi) but bigger size
/ebook      #Medium quality output (150 dpi) with moderate output file size
/screen     #Lower quality output (72 dpi) but smallest possible output file size
