Applying Licenses to Projects in IronPDF for Java

How to Get a License Key

Adding an IronPDF license key allows you to deploy your project live without restrictions or watermarks.

You can purchase an IronPDF license or sign up for a free 30-day trial license.

Step 1: Define IronPDF as a Java Dependency

<dependencies>
    <!-- Adds IronPDF Java. Use the latest version in the version tag.-->
    <dependency>
        <groupId>com.ironsoftware</groupId>
        <artifactId>ironpdf</artifactId>
        <version>20xx.xx.xxxx</version>
    </dependency>

    <!-- Adds the slf4j logger which IronPDF Java uses. -->
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-simple</artifactId>
        <version>2.0.3</version>
    </dependency>
</dependencies>

<dependencies>
    <!-- Adds IronPDF Java. Use the latest version in the version tag.-->
    <dependency>
        <groupId>com.ironsoftware</groupId>
        <artifactId>ironpdf</artifactId>
        <version>20xx.xx.xxxx</version>
    </dependency>

    <!-- Adds the slf4j logger which IronPDF Java uses. -->
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-simple</artifactId>
        <version>2.0.3</version>
    </dependency>
</dependencies>

Step 2: Apply Your License Key

import com.ironsoftware.ironpdf.License;

public class MyApplication {
    public static void main(String[] args) {
        // Apply your license key
        License.setLicenseKey("IRONPDF-MYLICENSE-KEY-1EF01");

        // Start using IronPDF!
    }
}

import com.ironsoftware.ironpdf.License;

public class MyApplication {
    public static void main(String[] args) {
        // Apply your license key
        License.setLicenseKey("IRONPDF-MYLICENSE-KEY-1EF01");

        // Start using IronPDF!
    }
}

IRONPDF_LICENSE_KEY=IRONPDF-MYLICENSE-KEY-1EF01

Step 3: Test if your key has been installed correctly

Here's how you can test the validity of your license key in Java code:

import com.ironsoftware.ironpdf.License;

public class LicenseTest {
    public static void main(String[] args) {
        String licenseKey = "IRONPDF-MYLICENSE-KEY-1EF01";

        // Check if the given license key string is valid
        boolean isValid = License.isValidLicense(licenseKey);

        if (isValid) {
            System.out.println("License key is valid.");
        } else {
            System.out.println("License key is invalid.");
        }
    }
}

import com.ironsoftware.ironpdf.License;

public class LicenseTest {
    public static void main(String[] args) {
        String licenseKey = "IRONPDF-MYLICENSE-KEY-1EF01";

        // Check if the given license key string is valid
        boolean isValid = License.isValidLicense(licenseKey);

        if (isValid) {
            System.out.println("License key is valid.");
        } else {
            System.out.println("License key is invalid.");
        }
    }
}

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