Syncfusion Blazor PDF Viewer SDK is a dedicated PDF rendering component for Blazor applications that enables in-browser viewing, annotation, printing, and downloading of PDF documents without relying on external web services. It uses a WebAssembly build of PDFium for efficient client-side processing and consistent performance across supported platforms.

Client-Side PDF Rendering

Render PDF documents directly within Blazor applications using the WebAssembly version of PDFium. This architecture removes the need for server-side rendering services and reduces JavaScript interop calls, resulting in responsive page loading, smooth scrolling, and reliable zooming behavior.

Optimized Performance And Memory Usage

Handle PDF documents with improved efficiency through optimized rendering and resource management. The component is designed to reduce memory consumption while maintaining fast loading, navigation, and interaction, even when working with large or complex files.

Text Search And Navigation

Enable users to search for text within PDF documents and navigate between matches with highlighted results. Built-in page navigation options such as thumbnails and direct page access help users move efficiently through lengthy or detailed documents.

Modern Navigation Toolbar

Provide users with an intuitive toolbar that centralizes navigation, zoom controls, page layout options, and document actions. Developers can configure and customize available commands to align with specific application requirements and user roles.

Annotation and Markup Support

Add and manage annotations such as highlights, shapes, freehand drawings, and comments directly within the PDF viewer. This functionality supports collaborative review workflows and enables programmatic control over annotation creation and persistence.

Interactive Form Filling

Enable users to complete interactive AcroForm fields including text boxes, checkboxes, radio buttons, and dropdown lists. The component supports data entry and form interaction within the Blazor interface, making it suitable for digital document processes.

Advanced Printing Support

Print PDF documents directly from the Blazor application with reliable handling of annotations, rotated pages, and large files. The printing process is optimized to maintain performance and efficient memory usage during output generation.

Download and Export Options

Allow users to download PDF documents after viewing or annotating them within the application. Developers can configure access to these capabilities to align with document management policies and security requirements.

Bookmark and Thumbnail Navigation

Display document bookmarks and page thumbnails to help users quickly locate specific sections within a PDF. This structured navigation support improves usability when working with lengthy reports, manuals, or technical documentation.
