Document processing involves more than creating and converting files. You may need to prepare content for AI retrieval, verify whether a signed contract has been modified, or extract data from existing documents. The Syncfusion® Document SDKs [2026 Volume 3](https://help.syncfusion.com/common/essential-studio/release-notes/v35.1.37) release introduces updates across several libraries. To make these updates easier to explore, we’re covering them in two blogs. In this blog, we’ll focus on the PDF, Document Chunking, and Data Extraction libraries, exploring their new capabilities and how they can help developers solve real-world challenges. In our upcoming blog, we’ll cover the updates to the Word, Excel, and PowerPoint libraries. Let’s look at what’s new in each library. ## **Introducing .NET Document Chunking** The new [.NET Document Chunking Library](https://www.syncfusion.com/document-sdk/net-document-chunking-library) (Preview) helps developers prepare documents for AI-powered retrieval by dividing content into meaningful chunks while preserving structure, hierarchy, and metadata. This is useful when building an AI assistant that retrieves information from company policies, technical manuals, and product documentation. Unlike fixed-length splitting, which can separate related information, document chunking helps retain meaningful sections for retrieval. The library supports PDF, Word, Excel, PowerPoint, and Markdown formats. Developers can use it to prepare content for retrieval-augmented generation (RAG) and semantic-search applications without implementing separate chunking logic for each format. For instance, an assistant answering a question about company policy can retrieve relevant sections from the prepared document chunks. ## JavaScript PDF Library is now production-ready The [JavaScript PDF Library](https://www.syncfusion.com/document-sdk/javascript-pdf-library) moves from preview to production-ready status in this release. Along with existing PDF creation, editing, page manipulation, form, and annotation capabilities, Volume 3 introduces updates to PDF security, digital signature validation, and document manipulation. These capabilities are useful for applications that handle contracts, financial records, approval documents, and other sensitive information. ### **Strengthen PDF Security** Applications that generate confidential financial statements or customer agreements may need to control who can open a document, modify its contents, or perform specific actions. The JavaScript PDF Library supports security capabilities such as: - RC4 and AES [encryption](https://www.syncfusion.com/document-sdk/javascript-pdf-library/encryption) - User and owner passwords - Document permission restrictions - Digital signatures - Signature validation - Long-Term Validation (LTV) signatures ![Secure PDF documents with encryption, passwords, permissions, and digital signatures.](https://www.syncfusion.com/blogs/wp-content/uploads/2026/10/pdf-security-1024x576.png) Secure PDF documents Encryption, passwords, and permission settings help control document access and operations. Digital signatures help verify document integrity and signing information, while LTV support embeds relevant validation information to support future signature verification. These capabilities are useful when applications need to protect sensitive PDFs or manage signed documents for long-term storage. ### **Validate Digital Signatures** Consider an application that receives digitally signed contracts from customers or business partners. Before sending these documents into an approval workflow, the application may need to check whether the documents have changed after signing and whether the signatures meet its validation requirements. The JavaScript PDF Library provides capabilities to: - Check document integrity. - Inspect signing certificate chains. - Evaluate timestamp information. - Check certificate revocation status. ![Validate PDF signatures](https://www.syncfusion.com/blogs/wp-content/uploads/2026/10/digital-signature-validation-1024x579.png) Validate PDF signatures These checks can help applications identify potential signature-validation issues before documents move into downstream business processes. For example, a contract-management system could validate incoming signed PDFs and flag documents that require additional review. ### **Generate** ** Multi-Page PDF Reports with Tables** Beyond security, the JavaScript PDF Library includes enhancements for generating structured PDF reports. Applications that generate invoices, statements, and reports often need to display large tables across multiple pages. The PDF grid supports structured tables with customizable layouts, formatting, and automatic pagination. Developers can use these capabilities to generate multi-page business documents without manually managing every page break. ![Generate multi-page PDF reports](https://www.syncfusion.com/blogs/wp-content/uploads/2026/10/pdf-grid-report-1024x679.png) Generate multi-page PDF reports ### Search text and customize PDF content Volume 3 also introduces improvements to PDF document manipulation, including: - Text search within PDFs - Image-based list markers - Enhanced annotation border effects Text search helps applications locate specific information within PDF documents, while image-based list markers and annotation border effects provide additional formatting options. These enhancements support applications that need to search, customize, and manage PDF content. ## Convert SVG graphics and HTML content into PDFs PDF generation becomes more challenging when documents contain graphics or content originally designed for the web. A report might include vector logos, diagrams, and charts, while an invoice might be generated from an HTML template. Volume 3 includes updates for both scenarios. - The [.NET PDF Library](https://www.syncfusion.com/document-sdk/net-pdf-library) now supports **SVG-to-PDF conversion**, allowing developers to preserve the quality and scalability of vector graphics such as logos, diagrams, illustrations, and charts when generating PDF documents. - The HTML-to-PDF engine has also been updated with newer Blink binaries, providing improved security and continued compatibility with modern web standards for accurate PDF generation. ![Convert SVG graphics to PDFs](https://www.syncfusion.com/blogs/wp-content/uploads/2026/10/svg-to-pdf-conversion-1024x584.png) Convert SVG graphics to PDFs For organizations generating reports, dashboards, proposals, and customer-facing documents, these enhancements help ensure visual consistency across digital and printed outputs. ## Extracting more value from business documents Beyond document creation and conversion, organizations increasingly need to extract information automatically. The [.NET Data Extraction Library](https://www.syncfusion.com/document-sdk/net-smart-data-extraction-library) expands those capabilities with new conversion and recognition features designed for content reuse and automation. ### PDF-to-Word and PDF-to-HTML conversion Developers can transform PDF documents into editable formats while preserving layouts, images, tables, and formatting. This simplifies document modernization, content migration, and workflow automation. ![Convert PDFs to editable Word documents](https://www.syncfusion.com/blogs/wp-content/uploads/2026/10/pdf-to-word-conversion.png) Convert PDFs to editable Word documents For example, a legal team can convert archived PDF contracts into editable Word documents instead of recreating the content manually. ### Barcode and QR code recognition The .NET Data Extraction Library supports barcode and QR code recognition in supported PDF and image documents. The extracted data can be returned as JSON for use in other applications. This capability can help automate identifier capture in workflows such as logistics, inventory management, manufacturing, and document intake. ## Frequently Asked Questions What is the .NET Document Chunking Library used for?The .NET Document Chunking Library helps developers prepare documents for AI-powered applications such as retrieval-augmented generation (RAG), semantic search, knowledge retrieval, and intelligent chat experiences.
