Getting Started with IronPDF

Installing IronPDF Java Library in Your Maven Project is a straightforward process. Follow the steps below to install the library using the provided dependency:

1. Open your Maven project in an IDE such as Eclipse, IntelliJ IDEA, or NetBeans.
2. Open the pom.xml file for your project.

Scroll down to the dependencies section and add the following code:

<dependency>
    <groupId>com.ironsoftware</groupId>
    <artifactId>ironpdf</artifactId>
    <version>YOUR_VERSION</version>
</dependency>
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-simple</artifactId>
    <version>1.7.30</version>
</dependency>

<dependency>
    <groupId>com.ironsoftware</groupId>
    <artifactId>ironpdf</artifactId>
    <version>YOUR_VERSION</version>
</dependency>
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-simple</artifactId>
    <version>1.7.30</version>
</dependency>

This code adds the IronPDF Java library and the slf4j-simple logging library as dependencies for your project.

1. Save the pom.xml file.
2. Build your project to download and install the IronPDF Java library and its dependencies.

You can now use the IronPDF Java library in your project. To do so, add the following import statement to your Java class:

import com.ironsoftware.ironpdf.*;

import com.ironsoftware.ironpdf.*;

You can now use the IronPDF for Java API to create, edit, and manipulate PDF documents.

You have successfully installed the IronPDF Java library in your Maven project using the provided dependency. You can now use the library to convert HTML documents to PDF, create PDF documents from scratch, and modify existing PDF documents.

Convert HTML to PDF file

To convert HTML content to a PDF file using IronPDF for Java, you can use the following Java code:

import com.ironsoftware.ironpdf.*;
import java.io.IOException;
import java.nio.file.Paths;

public class HtmlToPdfConverter {
    public static void main(String[] args) {
        // 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
        PdfDocument myPdf = PdfDocument.renderHtmlAsPdf("<h1>Hello World</h1> Made with IronPDF!");

        // Save the PdfDocument to a file
        myPdf.saveAs(Paths.get("html_saved.pdf"));
    }
}

import com.ironsoftware.ironpdf.*;
import java.io.IOException;
import java.nio.file.Paths;

public class HtmlToPdfConverter {
    public static void main(String[] args) {
        // 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
        PdfDocument myPdf = PdfDocument.renderHtmlAsPdf("<h1>Hello World</h1> Made with IronPDF!");

        // Save the PdfDocument to a file
        myPdf.saveAs(Paths.get("html_saved.pdf"));
    }
}

The above program sets the license key using the License.setLicenseKey method. It then sets the log path using the Settings.setLogPath method to specify the output folder where the log file should be saved.

Next, it uses the PdfDocument.renderHtmlAsPdf method to render the HTML as a PDF document. The HTML content is passed as a string argument to this method. In this example, the HTML content is a simple "Hello World" message.

After the PDF document is created, the program saves it to a file using the saveAs method, specifying the file path as an argument. In this example, the file is saved as "html_saved.pdf" in the current directory.

Convert HTML Files to PDF File Format

Using the HTML file to generate PDF files is a complex task. But IronPDF makes it very easy and with the help of IronPDF, we can do this task with a few lines of code.

import com.ironsoftware.ironpdf.*;
import java.io.IOException;
import java.nio.file.Paths;

public class HtmlFileToPdfConverter {
    public static void main(String[] args) {
        // Apply your license key
        License.setLicenseKey("YOUR-LICENSE-KEY");

        // Set a log path
        Settings.setLogPath(Paths.get("C:/tmp/IronPdfEngine.log"));

        // Render the HTML file as a PDF
        PdfDocument myPdf = PdfDocument.renderHtmlFileAsPdf("invoice.html");

        // Save the PdfDocument to a file
        myPdf.saveAs(Paths.get("html_file_saved.pdf"));
    }
}

import com.ironsoftware.ironpdf.*;
import java.io.IOException;
import java.nio.file.Paths;

public class HtmlFileToPdfConverter {
    public static void main(String[] args) {
        // Apply your license key
        License.setLicenseKey("YOUR-LICENSE-KEY");

        // Set a log path
        Settings.setLogPath(Paths.get("C:/tmp/IronPdfEngine.log"));

        // Render the HTML file as a PDF
        PdfDocument myPdf = PdfDocument.renderHtmlFileAsPdf("invoice.html");

        // Save the PdfDocument to a file
        myPdf.saveAs(Paths.get("html_file_saved.pdf"));
    }
}

First, the IronPDF library is imported along with the required Java IO classes. A license key is set to enable the use of the IronPDF library. The log path is set to the specified directory for logging purposes.

Next, the HTML file is rendered as a PDF document using the IronPDF renderHtmlFileAsPdf method. The resulting PDF document is stored in a variable named myPdf.

Finally, the PDF document is saved to a file using the saveAs method, with the output file path specified.

Convert URL to PDF File

The provided code can be used to convert any URL to a PDF document swiftly and save it to a file using the IronPDF library.

import com.ironsoftware.ironpdf.*;
import java.io.IOException;
import java.nio.file.Paths;

public class UrlToPdfConverter {
    public static void main(String[] args) {
        // Apply your license key
        License.setLicenseKey("YOUR-LICENSE-KEY");

        // Set a log path
        Settings.setLogPath(Paths.get("C:/tmp/IronPdfEngine.log"));

        // Render the URL as a PDF
        PdfDocument myPdf = PdfDocument.renderUrlAsPdf("https://ironpdf.com");

        // Save the PdfDocument to a file
        myPdf.saveAs(Paths.get("url.pdf"));
    }
}

import com.ironsoftware.ironpdf.*;
import java.io.IOException;
import java.nio.file.Paths;

public class UrlToPdfConverter {
    public static void main(String[] args) {
        // Apply your license key
        License.setLicenseKey("YOUR-LICENSE-KEY");

        // Set a log path
        Settings.setLogPath(Paths.get("C:/tmp/IronPdfEngine.log"));

        // Render the URL as a PDF
        PdfDocument myPdf = PdfDocument.renderUrlAsPdf("https://ironpdf.com");

        // Save the PdfDocument to a file
        myPdf.saveAs(Paths.get("url.pdf"));
    }
}

Here are the steps involved in converting a URL to PDF:

1. Import the necessary classes from the IronPDF library and from the standard Java libraries.
2. Set your IronPDF license key using the License.setLicenseKey method. You can obtain a license key from the IronPDF website.
3. Set the path for the IronPDF log file using the Settings.setLogPath method. This step is optional but recommended for debugging purposes.
4. Use the PdfDocument.renderUrlAsPdf method to render the URL as a PDF. This method returns a PdfDocument object that represents the generated PDF.
5. Use the PdfDocument.saveAs method to save the PDF to a file. This method takes a Path object representing the file path where the PDF should be saved.
