Reduce the size of a PDF file consisting of scanned images
It is wise to scan documents at the highest resolution possible as downsampling can be done at any point. The fastest way I found so far the tools of the ImageMagick suite or with GhostScript.
Assuming we have a PDF with images scanned at 600dpi and I want to downsample it to 150dpi and use JPEG compression at a ratio of 80% for sending it via mail.
convert -density 150x150 -compression jpeg -quality 80 INPUT.pdf OUTPUT.pdf
