iText for .NET is a free open-source .NET API for creating and working with PDF documents in C#/VB.NET applications. It lets .NET application developers write applications for generating, modifying, and extracting content from PDF files.

iText for .NET is a port of the original iText API, which was written in Java programming language. It was developed to provide PDF document processing features to .NET application developers. It is used in various domains such as document management systems, reporting tools, and other applications that require PDF generation and manipulation.
