You can also change PDFs on your iPhone without using a third-party app. When you have to share a PDF that has private information on it, data security becomes the most important thing.
That’s why you should use a password to protect your PDF. Your sensitive papers must be kept secret and have an extra layer of security to keep people from getting to them who shouldn’t.

Why Can’t I Find the Lock PDF Option in iOS 16
Recent changes to the Apple operating system or iOS may have made it harder to lock PDF files. Here are some possible reasons why:
- You want to make sure your PDF file in iCloud Drive is safe. iOS only lets you password protect PDFs that are saved on the device itself, not PDFs that are stored in iCloud. Because of this, you can only choose files that are already on your iPhone or iPad’s storage.
- You might not have iOS 16 on your iPhone or iPad. Since “Lock PDF” is only available in iOS 16, you’ll need to update your iPhone to the latest version of iOS before you can use it.
- The PDF file may have already been locked. The file can’t be unlocked any longer. When you share a PDF that has already been locked, you won’t see the “Lock PDF” choice.
