# To reduce the size of a pdf file:
gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -sOutputFile=output.pdf input.pdf

# Concatenate PDF files using GhostScript
gs -dNOPAUSE -sDEVICE=pdfwrite -sOUTPUTFILE=output.pdf -dBATCH file1.pdf file2.pdf file3.pdf

# Use ghostscript to shrink PDF files
gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/ebook -dNOPAUSE -dQUIET -dBATCH -sOutputFile=output.pdf input.pdf
# Explanation: Replace input.pdf and output.pdf with the original PDF name and the new compressed version's file name respectively. The key to this is the PDFSETTINGS option which can be tuned for various levels of compression. For scanned text documents, I find the ebook setting works well enough for most purposes but you can experiment with the options below.

    # -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)'

# Reduce PDF Filesize
gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/screen -dNOPAUSE -dBATCH -dQUIET -dColorImageResolution=600 -dMonoImageResolution=600 -sOutputFile=output.pdf input.pdf
