  • 2. PDF is widely used in our daily work. It’s very important to learn how to make a secure PDF as sometimes we don’t’ want it to be seen by some other people. The general method of encrypting a PDF is generate a password for it so that you must enter the valid command every time you open it. This article will tell you how to encrypt a PDF on Windows and Mac OS. These two tricks are very easy (especially the Mac OS one). Before we start, you should known two things: 1. All passwords have the possibility of being cracked 2. Don’t forget the passwords you set!
  • 3. 1. Encrypt PDF on Windows Visit www.pdfmate.com/setup_free_pdf_merger.exe to download the PDFMate Free PDF Merger and install it on your computer. Open the program and click “Add Files” to add PDF files to the program.
  • 4. At the “Output Setting” area of the interface, choose “Security” and select both “Open Password” and “Permission Password” options. Type any passwords you want. It’s better to set a longer password as that would be more difficult to be cracked. Click “Build” to generate a new PDF with password.
  • 5. Open the new PDF file and you will meet a window to ask for password. That means the PDF has encrypted successfully. Type the password you just set before and you can read it again.
  • 6. 2. Encrypt PDF on Mac OS Encrypting PDF on Mac OS is very easy as the original PDF viewer of Mac OS has the encryption feature. Open the PDF file with “Preview” and choose “File” – “Export” at the top of the window. Select “encrypt” and type a password, then click “OK” to save the PDF.
