iText 7 Core
iText 7 Core is a commercially licensed PDF library and SDK available for Java or .NET (C#). In the PDF library, developers will find the code to program PDF documents. You can also extend the functionality of iText 7 Core with iText add-ons.
When using iText PDF in a closed source environment, you will need to purchase an iText PDF commercial license.
How it works
To demonstrate the powerful high-level capabilities of the iText 7 library, here is a simple "Hello World!" example showing how to create a PDF in just a few lines of Java or C#:
Why use iText 7 Core?
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. 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. In addition to this, they can benefit from our rich and up-to-date technical documentation in the Resource Center.
Focus on the high level, business logic
High-level APIs allow you to keep focus on your business logic and document content as iText 7 Core offers an abstract document model.
Focus on the low level, with internal PDF structures
The low-level APIs give full access to the internal PDF structures, which allow you to read, insert, update and delete any PDF document.
