Method #2(Free):Use PDFMate Free PDF Merger to Password Protect Your PDF File

This is actually a PDF merger tool, but it also comes with the option to set a password to the file. The tool comes with both paid and free versions, however, as far as password protection is concerned, you can get that in free version too. The tool is created by PDFMate that is also responsible for many other PDF tools.

However, having a free to use tool also means you will have to live with its downside as well. First issue, it is a merger software not built for actually adding a password to PDF files, it is just one of its feature that can help you set a password. As it is a merger tool, it will create a new file that can be password protected (it doesn’t add password protection to the same file).

The interface is easy, but very unattractive when compared to Adobe Acrobat.The option for “Permissions” are also bit limited as compared to Adobe Acrobat. The tool definitely gets the job done without sacrificing on protection, if you are okay with all the tiny issues, then you can protect your files without spending a penny. Although, it is never recommended for commercial use due to all the flaws.

Just download the software from the PDFMate Website (it’s a 35MB file compared to 700MB Adobe Acrobat file) and launch the program. In the interface, click on “Add files”.

Now, choose the file which you would like to password protect and click on “Open”.

Once the file is open, click on it to highlight it and tick the checkbox next to “Open Password” under the heading “Security”. Once it is checked, you can add a desired password that will be used to open the file.

If you just want to add a password to the file and don’t require any merging then it is better to set the Layout option to “1IN1” to avoid any changes. Now, just click on big “Build” button and a new file will be created and showed to you in a folder. The changes will only be applied to new file, the old file will stay the same.
