PDFKit.NET is a fully managed .NET class library designed for the creation and manipulation of PDF documents, packaged as a single assembly that allows for straightforward xcopy deployment. It operates independently with no additional requirements beyond the .NET framework itself. At the heart of PDFKit.NET lies a coherent and user-friendly object model comprising various classes like document, page collection, page, canvas, shape, bookmark, annotation, and field. The development team's primary goal is to simplify the integration of this class library into larger applications. With PDFKit.NET 5.0, users can fill in text fields, checkboxes, and radio buttons, while also having the option to save the forms in either an editable state or as a flattened PDF. Additionally, this version introduces the ability to handle dynamic XFA documents through the new XFA processor API, enhancing functionality. Furthermore, PDFKit 5.0 enables users to extract all graphics from a page, compiling them into a collection of various shapes, which can include text, images, and curves, providing versatile options for document manipulation. This makes PDFKit.NET an invaluable tool for developers looking to incorporate robust PDF handling capabilities into their applications.

Generate a PDF from Microsoft Office files, safeguard the information, and seamlessly convert it into various formats. You can programmatically manipulate documents by reordering, inserting, and rotating pages, along with compressing the file sizes. Utilize the same cloud-based APIs that power Adobe's user-focused applications to efficiently provide scalable and secure solutions. Extracting text, images, tables, and other content from both native and scanned PDFs can be done, resulting in a well-structured JSON file. The PDF Extract API utilizes advanced AI technology to precisely recognize text elements and comprehend the natural flow of reading different components, such as headings, lists, and paragraphs that may extend across multiple columns or pages. Additionally, you can capture font styles and metadata, identifying characteristics like bold and italic text along with their respective positions in the PDF. The resulting information is formatted in a structured JSON file, with tables available in CSV or XLSX formats and images stored as PNG files. This comprehensive approach ensures that users can efficiently manage and manipulate their PDF documents while preserving essential data integrity.
