How to protect a pdf file. PDF Password Protect Free is a program for installing protection of pdf documents. Several types of encryption

If you want to remove a password from a PDF file, this can be done quite easily, provided that you know how to remove it. See how to remove password from PDF file using different methods.

PDF security can be useful, especially when you are transferring an important document that should not be accessed by outsiders. But in practice, using such a file sometimes annoys the recipient, who has to enter a password each time to open it. If this annoys you, you can easily remove the protection. There are two ways to do this - through the "print to PDF" function, that is, create a copy without a password, and also using Adobe programs Acrobat Pro.

Method 1: Remove password by printing method

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 the disk. You can use this mechanism to create a copy of a file. This copy will already be without a password.

For Windows 10 users

Windows 10 has built-in print to PDF functionality. It is enough to open a protected file in any text editor(you can even use the Edge browser as it also has built-in support) and then click on the printer icon. For example, in Edge, click "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. Printer "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 you like. Thus, a copy is created that is exactly the same, with the only difference that it does not have a password.

For Windows 8.1 and earlier users

If your computer is running Windows 8.1 or earlier, there is no built-in option for printing to PDF. But this does not mean at all that there is no way to remove the established protection. To do this, you can download the free BullZip PDF Printer utility.

After installing the program, a virtual printer is added, which allows you to convert content using the virtual print function. Open the protected document in any text editor and select the print option.

Select "BullZip PDF Printer" as the printer and click on "Print". A window will appear where you can save a copy. She will already be without protection.

Method 2: How to remove password through Adobe Acrobat Pro

The second way is to use full version Adobe Acrobat Pro software. If you don't have a license, Adobe provides a 7-day trial period, during which you can use all the features 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 a password to confirm opening the file.

Then click right click mouse in the document select in context menu item "Properties".

In the window that opens, go to the Security tab. Here you can change the security level. It is enough to select the “No protection” checkbox in the “Protection method” field.

A notification appears if you are sure you want to disable protection. Confirm execution by clicking on "OK" and close the document. When you close, you will be prompted to save the changes - click "Yes". Thus, you can remove the set password and now you can open any file without entering it.

This small and fast utility is designed to protect 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 to do this. For the program to work successfully, you must specify the path to the file to be encrypted, enter the user password and the 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 under the screenshot.

User password and owner password protection

This utility allows, firstly, to set a user password, which sets protection for opening a pdf document. Secondly, the utility makes it possible to set an owner password, which restricts access rights to the document. In this case, you can prohibit editing the pdf file, printing it, copying, and so on.

Reliable protection

After the document is encrypted, the protected file can be opened using either the user password or the owner's password. However, you can remove restrictions on access rights to a document only if you know the owner's password. Therefore, when encrypting a pdf document, these passwords are not recommended to be the same.

Several types of encryption

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 designed for use on a PC or laptop with operating system Windows, including Windows XP, Windows 7, Windows 8, Windows 10. In addition to the password protection function for pdf files, the program has several additional functions - removing the protection of a pdf document if there is an owner password and searching for a password to open a PDF document.
