カスタマイズ可能な透かしをPDFに簡単に追加して、ドキュメントのセキュリティを強化し、知的財産を保護し、ブランディングを強化

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.
  • Telerik UI PDF for WPF (part of Telerik UI for WPF) enables dynamic watermarking in PDFs, ensuring confidentiality, copyright protection, and professional branding.
  • IronPDF for .NET by Iron Software facilitates advanced PDF watermarking, allowing developers to overlay text or images for security and authenticity in .NET projects.
