PDF files have become one of the most popular formats for sharing your documents for personal and professional purposes. You can also edit PDF files right on your iPhone without third-party apps. Sometimes, when you have to share a PDF file containing confidential information, data security becomes a top priority.
That’s why you should secure your PDF file with a password. We’ll show you the steps to add a password to a PDF file(s) on your iPhone. We will share both ways to add a password with and without a third-party tool.
How to Add Password to PDF on iPhone and iPad
iOS 16 and iPadOS 16 updates bring the option to lock PDF files using the Files app. Adding a password, you can secure PDF files stored locally on your iPhone. Please note that files stored in iCloud cannot be password protected. We recommend that you update the software version on your respective device first.
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 General.
Step 3: Tap on Software Update.
Step 4: If an update is available, download and install it.
Once the installation is complete, here’s how you can password-protect PDF files on your iPhone and iPad.
Step 1: Open the Files app on your iPhone or iPad.
Step 2: Open the PDF file 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 a password for your PDF and re-enter it for verification.
Step 6: Click Done in the upper right corner to save the password.
Step 7: Tap Done again in the upper right corner to confirm.
Your PDF file is now password protected on your iPhone.
You can tap it and enter the password to access the file. Share this file and password with your contacts to prevent unwanted access.
Please note that you cannot remove the password from your PDF file.
Also, if your iPhone or iPad runs on an older software version and doesn’t support iOS 16 or iPadOS 16, here’s how you can lock your PDF.
Step 1: Open the Files app on your iPhone.
Step 2: Open the PDF file you want to secure with a password.
Step 3: Click the Share icon in the lower left corner.
Step 4: Select Lock PDF from the list of options.
Step 5: Add a password for your PDF and re-enter it for verification.
Step 6: Click Done in the upper right corner to confirm.
Step 7: Click Done again in the upper right corner to save the password.

Secure your PDF files
If you’re sharing agreements, certificates, or personal details in a PDF, it’s always a good idea to secure your PDF with a password. Using your iPhone, you can easily add a password to your PDF file(s) on the go. In addition to the document, you may be asked to convert the image to a PDF file. For example, when sharing photos for print, you are sometimes asked to share them as PDF files.
If you have any such photos on your iPhone or iPad, you can easily convert those photos to PDF without any third-party apps. You can then share those PDFs by Airdrop, email, or iMessage with your contacts right from your iPhone or iPad.
