Another way to generate PDFs is to use the Shortcuts app. Go to the Gallery in Shortcuts and search for PDF for a simple shortcut that converts anything you send to it into a PDF. This can be used to select specific content from a webpage or app, and convert just that to a PDF.
Shortcut actions can show up in your action lists just like any other action.
The last five items in the list below are all shortcut actions I sometimes use. I have a few more, but they only show up when the data type you are passing is compatible.
Date Stamp: Gets the current date and saves it to the clipboard.
Log This: Activates Siri dictation. Logs the voice input as text to the Log This note. (can be activated by Siri)
Log This Locations: Gets the current location and adds it to the Log This note. (can be activated by Siri)
NC Log: Renames a file with a YYYYMMDD date and standard name, then prompts where to save it.
Time Stamp: Saves the current time in 24hr format to the clipboard.
The Log This actions were created when I was caring for my Mom. Things like oxegen levels, start and stop times for exercise, when meds were taken, etc. It was not meant to be a permanent log, just something I could refer to when making entries in the paper log when I had time.
NC Log was to make keeping standard file names easier for my Net Control Logs.
The Stamps are just ways to quickly get the current time and/or date to paste into logs or other documents.
I also have a Make Smaller shortcut (not shown) that takes an image, makes it smaller, and saves it to an album in Photos. I use it on most of the screenshots I post here.
Anyway, if you do something a lot, like making PDFs of certain documents, it’s worth looking into Shortcuts. iOS 13.1 has made them easier to use.
