Create PDF Watermarks in .NET

Watermark annotation support gives developers greater control over branding, document status, and appearance in programmatically generated PDFs.

Create PDF Watermarks in .NET

Support for watermark annotations in a PDF component enables developers to add watermark content, such as text or images, as PDF annotations rather than directly modifying the page content. This provides greater control over properties such as position, appearance, opacity, and print behavior, while helping applications add branding, confidentiality notices, document status information, or other persistent visual identifiers programmatically.

Several PDF components for .NET feature support for watermark annotations, including:

  • Document Solutions for PDF .NET by MESCIUS lets you create watermark annotations with configurable text, appearance, positioning, opacity, and printing behavior.
  • Telerik UI for WinForms PdfProcessing allows you to add watermark annotations to PDF documents programmatically, supporting controlled placement and visual presentation.
  • IronPDF for .NET by Iron Software facilitates adding watermarks to PDFs programmatically, enabling developers to apply text or image-based content with configurable presentation options.
  • Aspose.PDF allows you to create watermark annotations in PDF documents, with control over annotation appearance, positioning, opacity, and other properties.
