I find using the /ebook setting for the compression is a good compromise between file size and quality.

If you want, you can specify another name for the new PDF with: ps2pdf -dPDFSETTINGS=/ebook -sOutputFile=Lesson5b.pdf Lesson5.ps This overwrites your previous Lesson5.pdf with a smaller file (a good reason for making a backup). Next, enter: ps2pdf -dPDFSETTINGS=/ebook Lesson5.ps For example, this example file was 3.1MB as a PDF and ballooned to 29MB as a PS file! Have faith. This creates a file named Lesson5.ps, and if you look at its size, you might be alarmed. The first step is to convert it to a PostScript file by entering: pdf2ps -dLanguageLevel=3 Lesson5.pdf In this example, I'll show you how to shrink a file named Lesson5.pdf.

So I pieced together the following by combining information from the man pages with various other bits of advice I found on the internet. The man pages for these commands are terse, and it was challenging to find good documentation for them and their settings. This solution shrinks the size of PDF files, making them easier to share via email.

I found an answer to the latter problem using the commands pdf2ps and ps2pdf, which are part of the Ghostscript package. Unfortunately, the quality of the scans-the words, numbers, and graphics-is unsuitable using the Text setting, but the files are quite large-up to 5MB for just a few pages-using the Image setting. Simple Scan has two resolution settings, Images and Text, and saves files as PDFs. Free online course: RHEL Technical Overview.
