Is iText PDF free?

Yes, the iText PDF library is open source, and can be used freely under the AGPL requirements. For more information, see below. The iText Core library has had 3 major releases: iText 2, iText 5, and iText 7. The good news is that all iText Core library versions including the latest one, iText 7, are open source. The license for iText 5 and iText 7 is however different than iText 2, let me elaborate: iText 7 Core and a number of open-source add-ons are available under the AGPLv3 open-source license: https://itextpdf.com/en/how-buy/agpl-license. If you cannot comply with the AGPLv3 license requirements, it is still possible to use iText 7 with a commercial license. iText 7 Core and its open-source add-ons already supersede all iText 2 and iText 5 functionality, but in addition there are also several closed-source add-ons which provide extra functionality. A complete overview of open-source and closed-source add-ons can be found in the product overview: https://itextpdf.com/en/products.
