How to Add Password to a PDF File on iPhone and iPad

PDF files have become one of the most common formats to share your documents for personal and professional purposes. You can also edit PDFs straight on your iPhone without needing a third-party app. Sometimes, when you have to share a PDF that contains confidential information, data security becomes the top priority.

That’s why it is recommended to secure your PDF with a password. We will show you the steps to add a password to your PDF file(s) on your iPhone. We will share both ways of adding a password with and without needing a third-party tool.

How to Add Password to PDF on iPhone and iPad
The iOS 16 and iPadOS 16 updates brought the option to lock a PDF file using the Files app. Adding a password, you can secure the PDF files stored locally on your iPhone. Do note that files stored in iCloud can’t be password protected. First, we suggest you update the software version on your respective device.

Note the steps will be the same on iPhone and iPad.

Step 1: Open the Settings app on your iPhone or iPad.

Step 2: Tap on General.

Step 3: Tap on Software Update.

Step 4: If an update is available, download and install it.

After the installation completes, here’s how you can password-protect a PDF file on your iPhone and iPad.

Step 1: Open the Files app on your iPhone or iPad.

Step 2: Open the PDF you want to secure with a password.

Step 3: Tap the drop-down menu at the top.

Step 4: Select Lock PDF.

Step 5: Add the password for your PDF and enter it again to verify.

Step 6: Tap on Done at the top-right corner to save the password.

Step 7: Tap on Done at the top-right corner again to confirm.

Your PDF file is now password protected on your iPhone.

You can tap on it and enter the password to access the file. Share this file and the password with your contacts to prevent unwanted access.

Please note that you can’t remove the password from your PDF file.

Alternatively, if your iPhone or iPad runs on an older software version and it doesn’t support iOS 16 or iPadOS 16, here’s how you can lock your PDF file.

Step 1: Open the Files app on your iPhone.

Step 2: Open the PDF you want to secure with a password.

Step 3: Tap the Share icon in the bottom-left corner.

Step 4: Select Lock PDF from the list of options.

Step 5: Add the password for your PDF and enter it again to verify.

Step 6: Tap on Done at the top-right corner to confirm.

Step 7: Tap on Done at the top-right corner again to save the password.

Using your iPhone, you can easily add a password to your PDF file(s) on the go. Other than documents, you might be required to convert images into PDF files.
