iText is a more versatile, programmable and enterprise-grade PDF solution that allows you to embed its functionalities within your own software for digital transformation.
iText Core is available under open source (AGPL) as well as a commercial license.
iText SDK available on AWS
iText is now available on the AWS Marketplace. iText Suite BYOL offers a wide range of common PDF tasks for developers to use at their utmost convenience using the REST API.
How it works
To demonstrate the powerful high-level capabilities of the iText Core 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 Core?
With iText Core you don't have to worry about PDF technologies and standards, you can just focus on your business needs and document content. The high-level API provides easy methods to create, and manipulate PDF documents in all kinds of ways, such as splitting, merging, form filling, and much more.
At the same time your development team has full access to all internal PDF structures, with the low-level API 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 Knowledge Base.
Focus on the high level, business logic
High-level APIs allow you to keep focus on your business logic and document content as iText 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.
