PDF security keeps your information safe.

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

You can add password security to PDFs to prevent unauthorised access and protect sensitive information. You can also customise 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 any time.

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.

Give it a try.

You can try some of our online tools right now to create a more secure PDF. Up your PDF security by adding a password online in a click — and see how easy working with PDFs can be with Adobe Acrobat.
