I use CUPS-PDF to automatically generate PDFs from documents, but the size of the outputted PDFs is astonishingly high (~8 Mb vs ~800 Kb of I file produced by File -> Save as PDF). Any suggestion on how to reduce the file size of the generated PDFs?

You can try changing the quality of the generated PDF. Edit the configuration file /etc/cups/cups-pdf.conf and change

-dPDFSETTINGS=/prepress
to
-dPDFSETTINGS=/screen

The available options are:

-dPDFSETTINGS=/screen (screen-view-only quality, 72 dpi images)
-dPDFSETTINGS=/ebook (low quality, 150 dpi images)
-dPDFSETTINGS=/printer (high quality, 300 dpi images)
-dPDFSETTINGS=/prepress (high quality, color preserving, 300 dpi imgs)
-dPDFSETTINGS=/default (almost identical to /screen)
