Reduce size of pdf scanned documents

Reduce PDF size

My experiments trying to reduce size of scanned pdf with 100+ pages (which breaks graphicsmagick convert).

converting to black and white version

./pdf-to-bilevel.pl file.pdf

conversion using ghostscript

This will resize your pdf into fixed dpi and in my expirience is less useful than converting it to black and white, especially on poor scans

Usage: ./pdf-optimize.sh file.pdf [screen]
# screen   low-resolution "Screen Optimized" 96 dpi
# ebook    medium-resolution "eBook"         150 dpi
# printer  output "Print Optimized"          300 dpi
# prepress output "Prepress Optimized"
# default
# kindle - special conversion to grayscale, 150 dpi
