How to password protect PDF documents on Microsoft Word

Yes, you can use Word to add a password to a PDF document, and here's how.

Word add password to PDF

Whether you use Windows 11 or Windows 10, you can use Microsoft Word to secure a PDF document with a password without the need for third-party software, such as Adobe Acrobat.

Microsoft Office apps like Word, PowerPoint, Excel, and Access include a feature to export a document as a PDF file with the option to encrypt the document using a robust 128-bit Advanced Encryption Standard (AES) password, which should be more than enough to keep content secure.

Using this feature, you can add a password for existing PDF documents or export Word documents as PDFs with the same protection.
