Option 2: Download the jar file

Optionally download the IronPDF Java .jar file manually.

Step 2: Apply Your License Key

Option 1: Apply license key in Java code

Add this code to the startup of your application, before IronPDF is used. This method is universally effective and straightforward.

import com.ironsoftware.ironpdf.*;

// Apply your license key
License.setLicenseKey("IRONPDF-MYLICENSE-KEY-1EF01");

// Start using IronPDF!
JAVA

Option 2: Apply license in config.properties config file

Add the following to your config.properties file:

IRONPDF_LICENSE_KEY=IRONPDF-MYLICENSE-KEY-1EF01

Step 3: Test if your key has been installed correctly

// Check if a given license key string is valid.
License.IsValidLicense(String licenseKey);

Note: After adding a license, always remember to clean and republish your application to avoid potential mistakes in deployment.
