That means the library is free to use in open source projects. The library has been using the AGPL license model since iText 5. In addition to this, they can benefit from our rich and up-to-date technical documentation in the Resource Center. At the same time your development team has full access to all internal PDF structures, offering them the possibility to read, insert, update and delete any PDF object they want. With iText 7 Core you don't have to worry about PDF technologies and standards, you can just focus on your business needs and document content. IText 7 Core is a straightforward, performant and extensible library that is ready to handle the challenges of today's digital document workflows. See some definitions from the iText site. The library is a collection of several components, but the primary concern of this article is the IText Core component. It can be used to create static or dynamic PDFs and manipulate already existing PDFs with minimum concern for the PDF standards. The iText library can be used to manipulate almost any PDF. To start, I'll begin with a short overview of the library to provide readers with a better understanding of the concept.
