In iOS 11 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, tap the Share button in the top right of the screen.
Then tap Create PDF. Here, you’ll be given the chance to edit the sheet by adding notes or annotations. To send the PDF by email, again press the Share button in the top right and choose Mail. Alternatively, press Done in the top left and then Safe File To… – you’ll then be able to save the file somewhere you can later access via the iPad’s Files app.
