Protecting a PDF with a password is an important step to ensure that sensitive information stays secure. PDFs often contain personal, financial, or confidential data, and adding a password helps prevent unauthorized access. Fortunately, the process is simple and can be done using various software tools.

Most PDF editors, such as Adobe Acrobat, allow users to set passwords directly. To do this, open the PDF file, select the “Protect” or “Encrypt” option, and choose a strong password. Make sure your password is unique, combining letters, numbers, and symbols to increase security. Some online tools also offer password protection for PDFs, but it is safer to use trusted software to avoid data leaks.
