Keep your work safe. Encrypt your PDF with a password.

You can add password security to PDFs to prevent unauthorized access and protect sensitive information. You can also customize security settings to restrict editing, modifying, printing, or copying the content of your PDF files. With Adobe Acrobat, you get advanced security features to keep your work as safe as possible.

Create a protected PDF in Microsoft applications.

Document security matters. If you’re working in Microsoft Word, Excel, Outlook, or PowerPoint, you can turn your document into a protected PDF document without even leaving the application.

Remove security anytime.

When PDF password protection is no longer needed, it’s just as easy to remove it as it was to add it. If you own the document or have permission, protected PDF files can be unlocked with the correct password, and security options can then be adjusted as needed. Adobe keeps your original document perfectly intact.
