PDF24 Creator is free PDF designer and PDF printer for creating PDF files. Password protection is one of the features software. You can password protect a PDF file to prevent it from being opened, and you can set security options to prevent it from being printed or copied from text and images.
Here's how it works:
- Download, install and open PDF24 Creator
- Upload the PDF file by dragging it to the right side of the window. Now you can see the file in preview mode. You can put any file there, not just PDF files.
- Click on the "Save As" icon on the toolbar to open the "Save As" dialog box.
- Select the PDF output filter and open the security page.
- Check the box “use security settings” and enter your passwords
- Click "continue" and then select the file where you want to save the new password-protected PDF file.
Differences between owner and user of PDF passwords
You can set two passwords on the security page. This could be the file owner's password, which is required to protect the file, as well as the user's password, which is required to open the password.
Please be aware that the owner has full access to the file, so it is better to choose different passwords. If both passwords are the same and someone opens a PDF file with that password, then they automatically have full access to the file because they opened the file as the owner. If you want to protect the file from printing and set a password for opening the file, then you must select a different password.

If you want to remove a password from a PDF file, it can be done quite easily, provided you know the removal methods. See how to remove a password from a PDF file using various methods.
PDF protection can be useful, especially when you are transmitting an important document that you don't want others to have access to. But in practice, using such a file sometimes irritates the recipient, who has to enter a password every time to open it. If this annoys you, you can remove the protection in a simple way. There are two ways to do this - through the “print to PDF” function, that is, create a copy without a password, and also using the program Adobe Acrobat Pro.
Method 1: Removing the password by printing
Print to PDF is a feature that allows you to export any document to this format. In this case, the document is not printed, but saved in the specified format on disk. You can use this mechanism to create a copy of a file. This copy will no longer have a password.
For Windows 10 users
Windows 10 has a built-in print to PDF feature. It is enough to open the protected file in any text editor (you can even use Edge browser, since it also has built-in support) and then click on the printer icon. For example, in Edge, click the three dots and select Print.
A window with parameters will open. In the Printer field, select “Microsoft PDF Printer” and click the Print button.
Of course, nothing will actually be printed. The Microsoft PDF Printer exports the document to PDF and instead of printing, a window will appear in which you need to specify where to save the file.
Select a folder and give it any name. This creates a copy that is exactly the same, the only difference being that it does not have a password.
For users of Windows 8.1 and previous versions
If your computer is running Windows 8.1 or earlier, there is no built-in PDF printing option. But this does not mean that it is not possible to remove established protection. To do this, you can download the free BullZip PDF Printer utility.
After installing the program, it is added virtual printer, which allows you to convert content using the virtual print function. Open the protected document in any text editor and select print.
Select “BullZip PDF Printer” as your printer and click on “Print”. A window will appear in which you can save a copy. She will no longer be protected.
Method 2: How to remove your password using Adobe Acrobat Pro
The second way is to use full version Adobe programs Acrobat Pro. If you don't have a license for it, Adobe provides a 7-day trial period, during which you can use all functions for free.
To use it you need to create account Adobe and then download the program. After installation, you need to log into your account to activate the 7-day license.
Then open the protected document in Acrobat Pro. Enter your password to confirm opening the file.
After click right click mouse in the document, select in context menu"Properties" item.
In the window that opens, go to the Security tab. Here you can change the security level. Just check the “No protection” checkbox in the “Protection method” field.
A notification will appear to let you know if you are sure you want to disable the protection. Confirm execution by clicking “OK” and close the document. When closing, you will be asked to save changes - click “Yes”. This way you can remove set password and now you can open any file without typing it.
In this article we will look at two ways protection pdf file. The first is setting a password to open pdf file and the second is protection against printing a document, copying content, changing (converting) a document. Installation of protection is possible when creating pdf.
For this you need a program PDF Creator. After you have downloaded and installed PDF Creator, double click mouse launch this program.
A settings window will open
Next, select “PDF” and click on the “Protection” tab
If we want to protect against opening, then check the box “A password is required to open.” (If you forget your password, it can be removed)
If we want to protect against printing a document, copying content, changing (converting), then in the “Prohibit user” item, check the following four boxes:
1) printing the document;
2) copy content;
3) change the document;
4) change comments.
After that, save the settings. In the next window, also click “Save”. A window will open where you need to specify passwords.
After specifying the password, the pdf creation process will be completed. We can see what our secure pdf looks like. If, when creating a pdf, you set a password to open it, then when you launch such a file, the following window will appear:
So, you have protected your pdf document.
This one is small and quick utility is designed to install protection on pdf documents. This free software will be indispensable if you need to put a password on pdf files, but there are no tools on your computer that allow you to do this. For the program to work successfully, you must specify the path to the file that needs to be encrypted, enter the user password and owner password, set restrictions on manipulations with the encrypted document, and select the encryption method. This simple program can be downloaded from the link located below the screenshot.
User and owner password protection
This utility allows you, firstly, to set a user password, which sets protection for opening pdf document. Secondly, the utility allows you to set an owner password, which limits access rights to the document. In this case, you can prohibit pdf editing file, printing it, copying it, and so on.
Reliable protection
After the document is encrypted, you can open the protected file using either the user password or the owner password. However, you can remove restrictions on access rights to a document only if you know the owner’s password. Therefore, when encrypting pdf document It is not recommended to make these passwords the same.
Multiple encryption types
In order to password protect a pdf file, the program provides a choice of encryption type: 40-bit RC4, 128-bit RC4, 128-bit AES, 256-bit AES. Moreover, AES encryption is considered more reliable. This tool is designed for use on a PC or laptop with an operating system Windows system, including Windows XP, Windows 7, Windows 8, Windows 10. In addition to the function of password protection of pdf files, the program has several additional functions - removing protection of a pdf document if there is an owner password and searching for a password for opening PDF document.
In OS X, you can password protect not only your documents, but also ordinary documents. For example, creating a password-protected PDF literally takes one minute, and now we'll look at how to do it.
First we need any document. It could be Pages file, Word, Excel or another - in the future we will still convert it to PDF format. For our experiments, I specially created a test Word document.
To convert a file to PDF, open any text editor, go to the “File” menu, select “Print” and then “Save as PDF”.
But it’s too early to save our new document. We go to the file security settings, where the system will prompt us to choose a password, without which access to the document will be impossible.
With this simple trick you can easily protect your document from prying eyes. When trying to hack a file, an attacker will only see strange symbols in place of its contents, in other cases you cannot do without a password. It is very convenient if someone else sometimes works on your computer.
Of course, to protect more high level it is recommended to use rather than separate files and folders. In this case, it will be possible to open it only after entering a special key, which is automatically generated by the system itself.
On the other hand, a professional hacker will definitely find a way to bypass any protection, especially built into operating system, so do not trust such methods to secure extremely important documents.
