If you are an iPhone or iPad user, the latest iOS 13 software update adds an interesting new feature. With the Safari web browser, you can now take a screenshot of an entire web page (not just the visible portion on the screen) and save the web page to a PDF file. This article details the procedure for doing so.
I’ve found this quite useful on a few occasions where I want to save the contents of a web page that I come across on my iPhone, and then edit the PDF file later to extract specific pages or images that I want to use elsewhere.
Note, this feature is specific to iOS 13 devices and only works with the Safari web browser (not Chrome or Firefox, unfortunately).
