Installing iText free trial for Java and .NET developers

This guide is for users of the iText Suite free 30-day trial. If you want to use iText under AGPLv3 terms or already have purchased a commercial license, see Installing iText for Java or Installing iText for .NET.

Thank you for your interest in the iText Suite PDF SDK, we hope you will enjoy using our product and share your experiences with us and the iText community. We will walk you through the installation process for the trial.

If you require any help during the trial period, you can contact Support to get professional assistance from our team.

How does your free trial work?

For 30 days you can try out the iText Suite—totally free—under the terms of iText’s commercial license. Learn more about our licensing options here.

Please note that the iText trial is only intended for evaluation purposes and is prohibited from use in a production environment. After the 30 days, the license will revert to AGPL mode. If the license is loaded after this period, iText Core and open-source add-ons will continue to work under AGPL but closed-source add-ons will stop working. To continue using iText Core or any of the add-ons, you should disclose your code to your users, or purchase a commercial license. Refer to the AGPLv3 terms for more information.

iText Core add-ons are not included in the iText Core commercial license—a separate commercial license is needed per add-on.

Pre-installation

To use the iText free trial you need to install a valid trial license and the license key library. The requirements to install the license and the license key library are as follows:

• Obtain a trial license, which is required to use iText’s proprietary libraries. You can request a 30-day free trial here.

• After accepting the terms of use, click the link provided in the email. This will download a zip file containing a license key file named (for example) “itextkey.json”. This JSON file contains information about who you are, and a key allowing you to use the software.

• To be able to load this license file you need an additional library—the license key library. If you have previously downloaded the license key library, please make sure you have the latest one.

Refer to the Compatibility Matrix to check which is the latest version of the license key library.

Installation

1. Make sure you have downloaded your individual trial license key, as instructed in "Pre-installation" above:

2. Download iText Core and your desired add-ons:

• For Java, you can find the latest instructions on where and how to download iText Core and add-ons here.

• For .NET, you can find the latest instructions on where and how to download iText Core and add-ons here.

Your license key will work for both.

3. Follow the instructions to download, install and load the license key and license key library. If you have any problems, make sure to check the "Troubleshooting" and "License key FAQs" listed after the installation instructions.

• You can verify your license is loaded correctly by checking the producer line on generated PDFs. As an example, the producer line for iText 9 would be “iText® Core 9.x.y © 2000-2025 Apryse Group NV”, followed by information on the type of license. For example:

  • “AGPL version”, when not using the licensing library or when using an invalid/expired license;

  • “Trial version”, when using the licensing library and a valid trial license;

  • “Licensed version”, when using the licensing library and a valid license.

4. That’s it, you’re ready to go! We’ll keep in touch via email throughout the trial period, so let us know if you have any questions.
