You can turn any type of document into a PDF on iPhone in seconds, and since the functionality is built into the Share option you don't need third-party apps to get started. Here's how to convert to PDF on iPhone or iPad.

  1. Open any type of document or image file on your iPhone or iPad running iOS 10 or later
  2. Tap Share at the bottom of the screen
  3. Scroll across the icons to find and select Print
  4. A preview will open onscreen: pinch to zoom in and view the document full-screen
  5. This preview is actually a PDF! To export it, press Share at the top right of the screen
  6. Choose to share your PDF via AirDrop, email or another app on your iPhone

In upcoming iOS 13 a new feature will enable you to grab full web pages as PDFs.
