Protect PDF with Password Online
Add robust password protection to your PDF documents to prevent unauthorized access and modification. Our Protect PDF tool lets you set both a document open password and a permissions password, using industry-standard AES encryption.
Two Levels of Protection
The document open password restricts who can view the PDF. The permissions password controls what authorized users can do, including whether they can print, copy text, edit content, or add comments.
