in thread Shrink Images and PDFs

For your PDF files, what does gs do or not do which reduce the PDF file size? Is it mainly ebook option?

Yes, I've found the ebook option a convenient way to downsample the resolution of the images embedded in a PDF to 150 DPI. So this script will have a significant effect on PDF files that are large due to them containing high-resolution images (like scans), and less of an effect on PDFs that are already smaller than ~1MB.
