It may not be well known, but iOS has several ways to save things as PDF and print webpages and other documents as PDF files. While one of the most popular methods involves using 3D Touch, another PDF generation approach is available to devices without that capability, and instead relies on a gesture trick to save something as PDF. The advantage to saving PDF files with the gesture method is that it works on iPad as well as iPhone and iPod touch, covering a much broader range of devices.

It’s quite simple too, though it is completely hidden from any obvious user interaction. We’re going to demonstrate this great PDF saving trick by saving a webpage as a PDF on iPhone, iPad, and iPod touch, but it works the same with other document types from common apps like Notes, Pages, Numbers, and many others. You’ll need a modern version of iOS 10 or newer to have this special save PDF gesture feature, it is not included in old releases, so update your device if need be.
