Compress PDF files with ghostscript

This can reduce files to ~15% of their size (2.3M to 345K, in one case) with no obvious degradation of quality.

ghostscript -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/printer -dNOPAUSE -dQUIET -dBATCH -sOutputFile=output.pdf input.pdf

Other options for PDFSETTINGS:

  • /screen selects low-resolution output similar to the Acrobat Distiller "Screen Optimized" setting.
  • /ebook selects medium-resolution output similar to the Acrobat Distiller "eBook" setting.
  • /printer selects output similar to the Acrobat Distiller "Print Optimized" setting.
  • /prepress selects output similar to Acrobat Distiller "Prepress Optimized" setting.
