Using IronPDF for Java
Define IronPDF as a Java Dependency
pom.xml Dependency
To define IronPDF as a dependency, please add the following to your pom.xml
:
<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.-->

Download jar file
Optionally download the .jar manually from https://search.maven.org/artifact/com.ironsoftware/ironpdf/2022.11.0/jar
First Build and Run
IronPdfEngine
binaries will automatically be downloaded when running the project for the first time. The IronPdfEngine
process will start when you call any IronPdf function for the first time, and stop when your application is closed, or when it enters an idle stage.
Start writing Java code
Once the dependence is defined, you can get started by adding the import com.ironsoftware.ironpdf.*
statement to the top of your Java code. Here is a simple sample HTML to PDF example to get started:
// Import statement for IronPDF Java
import com.ironsoftware.ironpdf.*;
// Apply your license key
License.setLicenseKey("YOUR-LICENSE-KEY");
// Set a log path
Settings.setLogPath(Paths.get("C:/tmp/IronPdfEngine.log"));
// Render the HTML as a PDF. Stored in myPdf as type PdfDocument
PdfDocument myPdf = PdfDocument.renderHtmlAsPdf("<h1> ~Hello World~ </h1> Made with IronPDF!");
// Save the PdfDocument to a file
myPdf.saveAs(Paths.get("html_saved.pdf"));
This is another simple example which demonstrates URL to PDF:
// Import statement for IronPDF Java
import com.ironsoftware.ironpdf.*;
// Apply your license key
License.setLicenseKey("YOUR-LICENSE-KEY");
// Set a log path
Settings.setLogPath(Paths.get("C:/tmp/IronPdfEngine.log"));
// Render the URL page as a PDF. Stored in myPdf as type PdfDocument
PdfDocument myPdf = PdfDocument.renderUrlAsPdf("https://ironpdf.com/java");
// Save the PdfDocument to a file
myPdf.saveAs(Paths.get("url_saved.pdf"));
PdfDocument pdfDocument = PdfDocument.renderUrlAsPdf("https://ironpdf.com/java");
Full Main.java Example
package org.example;
// Import statement for IronPDF Java
import com.ironsoftware.ironpdf.*;
import java.io.IOException;
import java.nio.file.Paths;
public class Main {
public static void main(String[] args) throws IOException {
// Apply your license key
License.setLicenseKey("YOUR-LICENSE-KEY");
// Set a log path
Settings.setLogPath(Paths.get("C:/tmp/IronPdfEngine.log"));
// Render the HTML as a PDF. Stored in myPdf as type PdfDocument
PdfDocument myPdf = PdfDocument.renderHtmlAsPdf("<h1> ~Hello World~ </h1> Made with IronPDF!");
// Save the PdfDocument to a file
myPdf.saveAs(Paths.get("html_saved.pdf"));
}
}
Further Settings Information
Note: Please note that all settings, logging, and licensing operations must be executed before any IronPDF methods are called.
Applying License Key
To apply your license key, add the following to the top of your method:
com.ironsoftware.ironpdf.License.setLicenseKey("YOUR-LICENSE-KEY");
Logging
IronPDF Java uses the slf4j logger. To enable logging use:
com.ironsoftware.ironpdf.Settings.setDebug(true);
To specify the IronPdfEngine log path add:
com.ironsoftware.ironpdf.Settings.setLogPath(Paths.get("C:/tmp/myIronPdfEngineLog.log"));
