Print anything to PDF on iOS

You can turn any printable thing into a PDF on iOS.

A webpage as a PDF on an iPhone
  1. Open the thing you want to print (web page, email, photo)
  2. Tap the Share button.
  3. Press the Print button.
  4. Now, find the preview screen and pinch out (two fingers, moving away from each other) until the preview becomes full screen (on phone 6S or greater, you can 3D-touch to pop it out)
  5. Now, you’re looking at a PDF, which has its own share control – you can now do whatever you want with it – save it to iCloud drive, email it, whatever you want to do.
