You can save any PDF onto an iPad, and read them in apps like Apple Books and Google Drive. Here's how to save PDFs on an iPad, with specific steps.

In iOS, Apple has extended the system's built-in screenshot feature to include the ability to save a full web page or "scrolling screenshot" as a multi-page PDF.

Preview automatically fills in the current PDF’s name. To avoid overwriting that file, enter a new descriptive name and click Save.
