This article will use IronPDF - a Java library for creating PDF documents programmatically.
Iron Software engineers have now developed IronPDF for Java which helps Java developers to create, edit, and manipulate PDF documents. IronPDF allows you to work with all aspects of PDF files. It offers developers a wide range of features to create and customize PDFs. It also helps to control the layout and formatting of the PDF document.
The main features include the ability to create a PDF file from various sources such as HTML, JavaScript, CSS, XML documents, and various image formats. In addition, IronPDF offers the abilities to add headers and footers to your PDF, create tables in PDFs, include digital signatures, and attachments. It supports complete multithreading and provides even more features!
To create a PDF Java conversion application, you need to download and install the following prerequisites:
IronPDF Java Library: Now you need to add the latest version of the IronPDF Java Library as a dependency to your PDF conversion application. Add the following IronPDF dependency to the pom.xml
file of your project:
<dependency>
<groupId>com.ironsoftware</groupId>
<artifactId>ironpdf</artifactId>
<version>LATEST_VERSION</version>
</dependency>
<dependency>
<groupId>com.ironsoftware</groupId>
<artifactId>ironpdf</artifactId>
<version>LATEST_VERSION</version>
</dependency>
You will also need to add the Slf4j dependency in the pom.xml
file.
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-simple</artifactId>
<version>2.0.5</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-simple</artifactId>
<version>2.0.5</version>
</dependency>
Once all the prerequisites are downloaded and installed, the project can now be used to convert HTML files to PDF documents in Java applications.
First, you need to add the IronPDF import to your main Java file where you want to run the code for the PDF converter. You need to import all the required classes, and this can be done with this single line of code:
import com.ironsoftware.ironpdf.*;
import com.ironsoftware.ironpdf.*;
Next, in the main method, enter the license key you obtained at the time of purchase or trial key using the IronPDF setLicenseKey
.
// Set the license key for IronPDF. Replace "Your license key" with your actual license key.
License.setLicenseKey("Your license key");
// Set the license key for IronPDF. Replace "Your license key" with your actual license key.
License.setLicenseKey("Your license key");
IronPDF can convert HTML content to PDF with simply one line of code.
// Convert an HTML string to a PDF document.
PdfDocument myPdf = PdfDocument.renderHtmlAsPdf("<h1> ~HTML2PDF in JAVA~ </h1> Made with IronPDF!");
// Save the PDF document to a file.
myPdf.saveAs(Paths.get("html_saved.pdf"));
// Convert an HTML string to a PDF document.
PdfDocument myPdf = PdfDocument.renderHtmlAsPdf("<h1> ~HTML2PDF in JAVA~ </h1> Made with IronPDF!");
// Save the PDF document to a file.
myPdf.saveAs(Paths.get("html_saved.pdf"));
In the above code, the renderHtmlAsPdf
method is used to pass the HTML string that will be converted to a PDF document. Then the saveAs
method is called to generate the PDF.
This creates a PDF document named "html_saved.pdf" which contains the HTML content passed as a string.
With the following code, you can convert the HTML file into a PDF document:
// Render the HTML file as a PDF. The resulting PDF is stored in myPdf as a PdfDocument object.
PdfDocument myPdf = PdfDocument.renderHtmlFileAsPdf("example.html");
// Save the PdfDocument to a file.
myPdf.saveAs(Paths.get("html_file_saved.pdf"));
// Render the HTML file as a PDF. The resulting PDF is stored in myPdf as a PdfDocument object.
PdfDocument myPdf = PdfDocument.renderHtmlFileAsPdf("example.html");
// Save the PdfDocument to a file.
myPdf.saveAs(Paths.get("html_file_saved.pdf"));
Here, the renderHtmlFileAsPdf
method is used to convert an HTML file into a PDF file. CSS and JavaScript can also be rendered along with the HTML file, preserving the layout and formatting of the HTML file.
Sometimes you want to create PDF files directly from a web page. For this purpose, the IronPDF library provides the method renderUrlAsPdf
to convert HTML from a URL to PDF. So the URL is used as an argument to the method.
// Render the HTML content from a URL as a PDF. The resulting PDF is stored in myPdf as a PdfDocument object.
PdfDocument myPdf = PdfDocument.renderUrlAsPdf("https://ironpdf.com");
// Save the PdfDocument to a file.
myPdf.saveAs(Paths.get("url.pdf"));
// Render the HTML content from a URL as a PDF. The resulting PDF is stored in myPdf as a PdfDocument object.
PdfDocument myPdf = PdfDocument.renderUrlAsPdf("https://ironpdf.com");
// Save the PdfDocument to a file.
myPdf.saveAs(Paths.get("url.pdf"));
You can also specify the formatting of the PDF file, such as page size, page orientation, margin size, layout, and many other properties simply by using the ChromePdfRenderOptions
and passing the layout options in the renderUrlAsPdf
method as the second argument.
After running the project with any of the above code samples, PDF files will be generated for all HTML content. Below you can see the sample output of "Convert HTML to PDF".

IronPDF renders all images and text without losing any formatting. Buttons are clickable, and text boxes are editable in the PDF file.
This article demonstrated how to create a PDF using the "Convert HTML to PDF" feature of the IronPDF Java API.
IronPDF for Java is free to use but for deployment purposes, it has a commercial license information which starts from only $749. You can also access the free trial of IronPDF for Java to test its functionality in production mode.
IronPDF for Java is a Java library designed to create, edit, and manipulate PDF documents programmatically. It supports converting various formats to PDF, including HTML, JavaScript, and images.
IronPDF for Java allows you to create PDFs from HTML, add headers and footers, create tables, include digital signatures, and manage various PDF customizations like layout and formatting.
You need the Java Development Kit (JDK), Maven, and the IronPDF Java Library installed. Additionally, you must add the Slf4j dependency to your project.
Use the `PdfDocument.renderHtmlAsPdf` method, passing the HTML string you want to convert. Then, save the PDF document using the `saveAs` method.
You can use the `PdfDocument.renderHtmlFileAsPdf` method, providing the path to the HTML file. The resulting PDF can be saved with the `saveAs` method.
Yes, you can convert a web page URL to a PDF using the `PdfDocument.renderUrlAsPdf` method, passing the URL as an argument.
Yes, IronPDF can render CSS and JavaScript along with HTML, preserving the layout and formatting in the resulting PDF.
IronPDF for Java offers a commercial license starting from $liteLicense. It also provides a free trial to test its functionality in production mode.
You set the license key using the `License.setLicenseKey` method in your main Java file, replacing 'Your license key' with your actual license key.
IronPDF for Java excels in preserving the formatting of the original document, supports multithreading, and offers extensive features for PDF customization.
