Ironpdf License Key
using IronPdf;// Place this at the very beginning of your application entry point IronPdf.License.LicenseKey = "IRONPDF.MYCOMPANY.2023.ABCD1234EFGH";
// Now you can use IronPDF var renderer = new ChromePdfRenderer(); var pdf = renderer.RenderHtmlAsPdf("<h1>Hello, PDF!</h1>"); pdf.SaveAs("output.pdf");
You can generate multiple license keys under one account. Use a trial key for local development and your paid key for staging/production. This prevents accidental leakage of your production key.
After setting the key, you can verify that it is working:
bool isValid = IronPdf.License.IsValidLicense; Console.WriteLine($"License valid: isValid");
string licenseType = IronPdf.License.LicenseType; Console.WriteLine($"License type: licenseType");
Also, generate a simple PDF and check for the absence of the red watermark:
var renderer = new ChromePdfRenderer();
var pdf = renderer.RenderHtmlAsPdf("<h1>Test License</h1>");
pdf.SaveAs("test.pdf");
If the watermark is gone, the license is correctly applied.
Cause: You have exceeded the number of allowed developers or machines. A Single Developer license allows one named developer but unlimited deploys to servers. However, simultaneous usage from multiple developer machines triggers this.
Fix: Purchase additional developer seats. Or ensure only one developer's machine runs the code during build.
This usually happens if the application cannot access the config file or if the key format has been corrupted during deployment.

Understanding IronPDF License Keys: A Complete Guide If you are developing .NET or Java applications that require high-quality PDF generation, you’ve likely encountered IronPDF. While the library is famous for its "HTML-to-PDF" capabilities, moving from development to a live production environment requires a valid IronPDF license key.
This guide covers everything you need to know about acquiring, activating, and managing your license keys to ensure your deployment is seamless and legal. Why Do You Need an IronPDF License Key?
IronPDF is a commercial library. While it offers a free trial for development purposes, a license key is required to:
Remove Watermarks: Trial versions place a "PRO" watermark on every page generated.
Enable Production Use: Legal compliance for deploying applications to live servers, clouds (Azure, AWS), or desktop clients.
Access Support: Licensed users get priority technical support and direct access to the engineering team.
Ensure Security: Licensed versions receive the latest security patches and updates. Types of IronPDF Licenses
Iron Software offers several licensing tiers tailored to different business sizes and project needs:
Lite License: Best for individual developers or small projects. It typically covers one developer and one internal application.
Plus License: Aimed at small teams. It often includes support for more developers and multiple locations or web applications. using IronPdf; // Place this at the very
Professional License: The standard for enterprise-level projects. It includes coverage for large teams, SaaS services, and OEM redistribution rights.
Free Trial Key: You can request a 30-day free trial key from the IronPDF website to test the full feature set without watermarks before committing to a purchase. How to Get an IronPDF License Key 1. Requesting a Free Trial
To test IronPDF in a production-like environment without watermarks: Visit the IronPDF License Page. Enter your email address in the "Free Trial" section. The license key will be sent instantly to your inbox. 2. Purchasing a Perpetual License
IronPDF uses a perpetual licensing model, meaning you pay once and own that version forever. You can purchase these directly through the Iron Software website or via authorized resellers. How to Install Your IronPDF License Key
Once you have your key (a long string of alphanumeric characters), you need to register it in your project. There are three common ways to do this in .NET: Method 1: Web.config or App.config (Easiest)
Add the key directly to your configuration file. IronPDF will automatically detect it.
Set the license key in your application's entry point before any IronPDF methods are called.
IronPdf.License.LicenseKey = "IRONPDF-MY-LICENSE-KEY-12345"; Use code with caution. Method 3: Environment Variables
For cloud deployments (like Azure or Docker), you can set an environment variable named IronPdf_LicenseKey. This keeps the key out of your source code for better security. Troubleshooting Common License Issues
"License Key Not Found": Ensure the key is set before you call any ChromePdfRenderer functions.
Watermarks Still Appearing: Check that there are no hidden spaces in the key string and that the key hasn't expired (if using a trial).
Deployment Errors: Ensure the license type matches your deployment. For example, a "Lite" license may not work if you are deploying a SaaS product intended for thousands of external users. Conclusion
An IronPDF license key is the bridge between a successful local prototype and a professional, watermark-free production application. Whether you are using a 30-day trial or an Enterprise perpetual license, the setup process is designed to be developer-friendly.

The "proper story" of the IronPDF license key is a transition from a watermark-only trial to a strict, key-required system that allows developers to test functionality before committing to a commercial license. How the Licensing Works
IronPDF previously allowed free use for development with a watermark, but starting from version 2024.1.20, a valid license key (even a free trial key) is required to run the library in any project. Without one, the library will throw a LicensingException.
