Navigate PDFs Faster with Bookmarks

April 24, 2026
Provide structured, tree-based navigation that lets users jump directly to relevant sections and interact with documents more efficiently.

Bookmark navigation in a PDF Viewer enables developers to expose the hierarchical bookmark structure embedded within a PDF so users can quickly jump to specific sections or pages. It typically presents bookmarks in a tree view synchronized with the document, allowing programmatic control and event handling for selection changes. This capability improves usability in applications that handle large or structured documents by reducing manual scrolling, supporting faster content discovery, and providing a more organized reading experience.

Several WinForms PDF Viewer components support bookmark navigation, including:

Enable In-PDF Annotations for Clearer Feedback

April 21, 2026
Allow users to add notes, highlights, and visual markers directly within documents, keeping feedback clear and accessible in one place.

Annotation capabilities in PDF Viewer components allow users to interact with documents through visual and textual markup, supporting review, collaboration, and documentation processes. Tools such as Line, Rectangle, and Free text help highlight structure and add clarity, while Sticky note and Stamp annotations provide contextual feedback and status indicators. By embedding these capabilities directly into a viewer, applications can offer a cohesive experience for editing and reviewing PDFs without requiring external software.

Common annotations include:

  • Ellipse annotations offer a circular or oval shape tool for highlighting regions in a less rigid form than rectangular annotations.
  • Free text annotations let users insert editable text anywhere on the page for inline commentary or corrections.
  • Freehand draw (Ink) annotations enable natural, pen-like input for signatures, sketches, or handwritten notes.
  • Line annotations allow users to draw straight connectors or highlights between points, often used for pointing out relationships or alignment.
  • Rectangle annotations provide a way to frame areas of interest, making it useful for emphasizing sections of a page.
  • Stamp annotations apply predefined or custom labels, such as approval or review statuses, directly onto the document.
  • Sticky note annotations add comment markers that can store detailed feedback without cluttering the document visually.

Remove Sensitive Data from PDFs

April 20, 2026
Implement PDF redaction in ASP.NET Core applications to protect sensitive information and prevent access to confidential data.

PDF redaction is the process of permanently removing sensitive or confidential information from a document so that it cannot be recovered or viewed. Unlike simple visual masking, true redaction deletes the underlying content, ensuring it is not accessible through copying, searching, or metadata extraction. This capability is essential for regulatory compliance, data protection, and secure document sharing, particularly in industries that handle personal, financial, or legal information.

Several ASP.NET Core PDF components allow you to redact PDFs, including:

  • Document Solutions for PDF by MESCIUS provides a .NET API that enables developers to define and apply redaction regions and permanently remove sensitive content from PDFs.
  • ImageGear for .NET by Accusoft includes redaction annotations allowing applications to mark and obscure confidential information within documents.
  • Syncfusion ASP.NET Core PDF (part of Syncfusion Essential Studio Enterprise) offers redaction support, with APIs to mark and remove sensitive text or images.
