You can save entire web pages as PDFs to send to others. Find an interesting article? Send the whole thing to someone so they can read it without needing an internet connection!
Alternatively, you might wish to grab a web page to insert into a presentation or other document. This tool lets you easily share web pages.
First, open a web page, or once you happen to find an interesting page in Safari, take a screenshot by pressing the Side button and Volume Up button simultaneously. Or, if you have an iPhone with a Home button, you can take a screenshot by pressing the Lock button and the Home button.
In the screenshot editing menu, tap Full Page at the top of the screen. You can annotate the capture if you wish.
Press Done, and then Save PDF to Files. Or, to send the PDF elsewhere, tap the share button in the top-right and choose an appropriate action.
