How to Use the Unlock PDF and Lock PDF for iOS Feature

Unlock PDF and Lock PDF are two useful features in the pdfFiller app for iOS that allow you to easily manage your PDF documents. Here is a step-by-step guide on how to use these features:

Launch the pdfFiller app on your iOS device.
Tap on the 'Unlock PDF' or 'Lock PDF' option from the main menu.
If you want to unlock a PDF, select the 'Unlock PDF' option. If you want to lock a PDF, select the 'Lock PDF' option.
Choose the PDF document you want to unlock or lock from your device's storage or cloud storage services.
Once you have selected the PDF, the app will prompt you to enter the password for the document. If the PDF is already unlocked, you can skip this step.
Enter the password for the PDF and tap on the 'Unlock' or 'Lock' button.
The app will then process the PDF and remove the password if you chose to unlock it, or add a password if you chose to lock it.
Once the process is complete, you can access the unlocked or locked PDF from the app's document list.
You can now view, edit, sign, or share the unlocked or locked PDF as needed.

Using the Unlock PDF and Lock PDF features in the pdfFiller app for iOS is a convenient way to manage the security of your PDF documents. With just a few simple steps, you can unlock or lock your PDFs and ensure their privacy and protection.

Fernando G
Amazing software except for the licensing. I just want to pay for when I need it. For a business the month to month is great, but for a single time user it is a bit tougher.
Timi E
I have not been able to figure out how to use my mouse and just scroll/roll thru the doc. I have to go to the left and click on page 2, to get to page 2, I can't just use the roller on the mouse to move.
