SwifDoo PDF

When you need to transfer files containing sensitive information, passwords are the most common security method. In the case of a single file, you will probably encounter a password-protected PDF document.

Many people choose to set a password for PDF files to prevent others from editing or copying the content. Is there any solution to protect a PDF? The answer is yes.

Before you learn how to protect a PDF file with passwords, you should know that PDF password codes have two types: the user password and owner password. The former will block you from the PDF and this one will block you from editing.

Password types

In the case of PDF files, you will encounter two types of passwords, concerning the entire document or only some of its functions.

  • Document opening password

Files containing confidential data are most often protected with this type of password. It prevents someone who doesn’t have the file from viewing it. When you try to open a document, you are prompted to enter it.

To protect your content, you can use encryption with a password. This prevents third parties from viewing or modifying the content without your consent.
