Saving webpages to PDF is quite terrible, because it often breaks things into "pages" and you end up with blank headers and footers on each page breaking the flow. You also very often have things cut off from the right-hand side of the webpage.

You have these options:

- SiteSucker to preserve a perfect copy of the website, though I'd use a VPN, 1 or 2-sec delay, and spoof user agent

- Firefox with the SingleFile extension lets you save an HTML file that includes all resources, much better than the Save As option in Chrome/Firefox
