When we save PDF files, we usually encrypt the files. What should we do if only part of the files need to be encrypted? The editor below will teach you a method to encrypt part of the PDF content!
1. Turn on the computer, enter "Swift PDF Editor" in the browser, find the software and download and install it to the computer.
2. Run the software, click the "Open" button, open the PDF file for which you want to set a password and add it to the operation page of the Swift PDF Editor.
3. After the PDF file is added to the software's operation page, we click the "Document"-"Encryption"-"Mark Encrypted Part" button at the top of the software interface.
4. Then find the content you want to encrypt, hold down the left mouse button, drag it, and smear the content you want to encrypt. After smearing, right-click the mouse, find and click "Apply Selected Encryption" in the drop-down menu bar that appears, and the content will be encrypted.
5. After processing, save the PDF file.
