For developers, it offers a straightforward way to integrate lightweight commenting functionality into document-centric applications, enhancing usability and facilitating more efficient communication among users.

Watermarks in PDFs are semi-transparent text or image overlays that serve as a security and branding tool by marking documents with identifying information. They help protect intellectual property, prevent unauthorized distribution, and reinforce authenticity by displaying ownership, confidentiality, or document status (e.g., "Draft," "Confidential," or "Approved"). Watermarking also enhances professionalism by incorporating company logos or copyright notices. Common use cases include securing legal contracts, corporate reports, research papers, and sensitive business documents to ensure proper handling and compliance. By integrating customizable watermarking, organizations can maintain control over their digital documents while preserving readability and usability.

Several .NET WPF PDF components allow you to add watermarks, including:

  • Syncfusion WPF PDF (part of Syncfusion Essential Studio Enterprise) lets you add customizable watermarks to PDFs, enhancing security, branding, and document control.
