How to encrypt and add watermark to PDF for free with pdfFiller

Encrypting and adding a watermark to your PDF documents helps protect sensitive information while ensuring your work remains recognizable. With pdfFiller, you can accomplish this seamlessly and without cost.

What is encrypting and adding a watermark to PDFs?

Encrypting a PDF refers to the process of securing the document with a password or other protection methods, ensuring that only authorized users can access its contents.
