iText Suite refers to the complete line of products comprising the open-source iText Core PDF library and its add-ons. The iText Suite is a fully-featured SDK for PDF development that allows you to seamlessly embed extensive PDF functionality into your software or workflows.

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.

Why use iText Suite?


The iText Suite builds on over a decade of lessons learned from iText 5 (and iTextSharp) development. The latest release of iText, version 8, is a simpler, more performant and extensible library that is ready to handle the increased challenges of today’s document workflows, one add-on at a time.

We believe the iText Suite is the best PDF SDK out there. With the open-source iText Core PDF library at its heart, and a whole range of add-on functionality, it’s no wonder iText is considered “the developers choice” for PDF. Check out what’s available in the iText Suite below.

  • Future extensibility.
  • Gentle learning curve with extensive documentation and examples
  • Comprehensive out of the box functionality, with the flexibility to extend and customize.
  • Focus on easy integration and open standards.
  • Unicode for bookmarks, PDF names, PDF strings, passwords, etc.
  • Up to date hashing and encryption algorithms for digital signatures and document security.
  • Support for multi-gigabyte files and documents with thousands of pages.
