itext7 9.6.0

iText represents the next level of SDKs for developers that want to take advantage of the benefits PDF can bring. Equipped with a better document engine, high- and low-level programming capabilities and the ability to create, edit and enhance PDF documents, the iText PDF library can be a boon to nearly every workflow. iText allows you to build custom PDF scenarios for web, mobile, desktop or cloud apps in .NET.

iText was built on nearly a decade of lessons learned from iText 5 (iTextSharp) development. It 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.

The iText Suite consists of iText Core and several add-ons. The add-ons are accessible as different packages.
