Here's a one-liner from my snippets collection (source lost), which
yields impressive results of up to >80% file size reduction on badly
crafted (vector/text-heavy) PDF files:
# gs -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 \
-dPDFSETTINGS=/ebook -sOutputFile=output.pdf input.pdf
Other possible parameters for -dPDFSETTINGS are /screen, /printer and
/prepress. (The /screen setting tends to mess up embedded graphics,
while the /ebook preset preserves even smaller QR-codes in a decodable
quality.)
