Simple Scan has two resolution settings, Images and Text, and saves files as PDFs. 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. I found an answer to the latter problem using the commands pdf2ps and ps2pdf, which are part of the Ghostscript package. This solution shrinks the size of PDF files, making them easier to share via email.

The man pages for these commands are terse, and it was challenging to find good documentation for them and their settings. So I pieced together the following by combining information from the man pages with various other bits of advice I found on the internet.

Many of the documents you receive come in PDF format. Sometimes those PDFs need to be manipulated. For example, pages might need to be removed or added, or you might need to sign or change a specific page.

There are some fancy graphical user interface tools that let you edit PDFs, but I have always been most comfortable with the command line. Of the many command-line tools for this task, the ones I use when I want to modify a PDF are qpdf and poppler-utils.
