How to put a password on a PDF file?

Security is the first word in today’s digital world. Although user information is vulnerable to being stolen at any moment, there are ways to protect it. Putting a password on PDF files is one of these ways.

This not only prevents other users from accessing the PDF files, but also deprives others of the ability to edit and change them. So if you want to create or send a PDF with more security, stay with us until the end.

Use Adobe Acrobat Pro DC

Adobe Acrobat is a service for editing, changing and generating PDF files. The program is free for seven days, and if you want to use Adobe Acrobat again for your PDF files after this period, you must pay $14.99 per month.

But in addition to the ability to create and edit PDF, one of the features of the professional version of Adobe Acrobat is to put a password on the files:

1 – To do this, first open the PDF file with the program and then select the Protect option from the right menu.

2 – Selecting Protect will show you a new specialized toolbar. In this bar, click on Encrypt and then select Encrypt With Password from the available list.

3 – With this, the Password Security – Settings panel will be displayed. Find the Document Open section, check the Require a password to open the document option, and then write the password you want. This password will be used when you want to open the file.

Here, take a look at the green boxes next to the code. These boxes indicate how strong or weak the password is.

4 – But maybe you want to leave a password for printing or editing PDF. At the bottom of the Password Security – Settings panel, there is a section called Change Permissions Password. Write the password you want here so that the user will have to enter the password for changes to the file.

5 – After entering the passwords, click OK at the bottom of the Password Security – Settings panel.

The best paid alternative to Adobe Acrobat

Not too keen on Adobe products and still want to use a better program than free apps? novaPDF Pro is the best possible option. The program may not have the freedom of action that Adobe Acrobat Pro DC gives the user, but it can still get you started:

1 – If you want to encrypt a PDF through novaPDF Pro, you must first open the file in the program. For this, after installing the program, the following page will be displayed. Select the Browse option and then specify the PDF file. Now click on Open.

2 – Then select Create option. This will bring up a box that says your printer has been selected as the default printer. Click OK.

3 – Now the Save PDF file panel should be shown. In this panel, first check Protect PDF document. Then click on Passwords at the bottom right. In the new section that has been opened, there are two empty spaces for entering the password.

In order to force the user to enter the password when opening and viewing the PDF, fill in the upper part (user password). If you want to edit the file without a password, put a password in the bottom part (owner password). To put it simply, the user password is for opening the file and the owner password is for editing the file.

4 – After writing the passwords, click Finish. Then select OK in the Save PDF file panel. If your encryption operation has been completed successfully, the program will ask the user for a password after running the PDF file.

It is not bad to add that novaPDF Pro does not use a separate PDF platform and integrates with the appropriate software of the computer itself. For example, if you enter the file password, the PDF will open with Adobe.

Note: There are three different versions of novaPDF and all of them provide different features to the user. But among all these versions, only the professional version (novaPDF Pro) has the ability to encrypt PDF.
