We have used iText for over 7 years in the DocuSign flagship product, our eSignature services. We use it with the purpose of extracting text, applying watermarks, and performing other general purpose PDF functions. We use iText to provide high availability and a reliable service to our customers and their documents.

iText is very readable and easy to understand. Also, in iText I don't need to write lots of code, you already provide almost all the methods necessary to do something.

Using the iText DITO Editor to develop our report templates is a huge time saver. I can now do in just 45 minutes what would have taken over two weeks to do in code using other PDF libraries!

We chose iText over other open source solutions because it was really quick and easy to develop our application using iText. That's thanks to the guides and documentation available on the iText website, and the many examples on developer communities like Stack Overflow.
