Instructions
In this example, we are using the Safari app and printing the web page https://www.ttu.edu. However, the same procedure will work for saving virtually anything in any app to PDF.
1) Open your preferred app and prepare the content to be captured.
TIP: If printing a web page, ensure that the page is completely finished loading.
2) Take a screenshot. Immediately proceed to the next step.
3) The screenshot thumbnail from the previous step will appear in the corner of your screen. Before it disappears, tap the thumbnail (that is, screenshot preview).
4) Tap the Full Page tab.
5) In the top left-hand corner, tap Done.
6) Tap Save PDF to Files.
7) Choose the location where you wish to save the PDF.
8) In the top right-hand corner, tap Save.
Outcome
The content has been saved as a PDF file.
