NXPowerLite Desktop is great for reducing the size of scanned PDFs, including multipage documents. I set up the software for best quality reduction while adding an extension for the newly created file (reduced in memory size) created by the program - that way I don't risk compromising the original file. Many of my files were reduced over 90% in memory size without compromising image quality / dpi. I have dragged and dropped over 100 MB of files at a time without a hitch, including a document over 60 pages. It's so easy and fast, doing batches of files at once, and then sharing and emailing reasonably sized files without hurting image quality. (Note: I chose best quality reduction of the 9 levels available). I chose the one-time purchase instead of the subscription option, which is great for individuals who won't be needing it all the time. It gave me a trial period, and after I saw what it could do I quickly bought it.
