Java - Convert URL or HTML Strings to PDF

In this article, I am going to introduce how to convert an URL (or a web page) and HTML strings to PDF by using Free Spire.PDF for Java with QT plugin. The plugin is an open-source library and be downloaded from the following links. Download the package that fits in with your operation system, and unzip it somewhere on your hard drive.

Installing Spire.Pdf.jar

If you create a Maven project, you can easily import the jar in your application using the following configurations. For non-Maven projects, download the jar file from this link and add it as a dependency in your application.

Example 1. Convert URL to PDF

import com.spire.pdf.graphics.PdfMargins;
import com.spire.pdf.htmlconverter.qt.HtmlConverter;
import com.spire.pdf.htmlconverter.qt.Size;

public class ConvertUrlToPdf {

    public static void main(String[] args) {

        //Specify the url path
        String url = "https://www.stackoverflow.com/";

        //Specify the output file path
        String fileName = "output/Result.pdf";

        //Specify the plugin path
        String pluginPath = "E:\\Products\\Java\\plugins-windows-x64";

        //Set plugin path
        HtmlConverter.setPluginPath(pluginPath);

        //Convert URL to PDF
        HtmlConverter.convert(url, fileName, true, 1000000, new Size(1000f, 900f), new PdfMargins(0));
    }
}

Example 2. Convert HTML string to PDF

import com.spire.pdf.graphics.PdfMargins;
import com.spire.pdf.htmlconverter.LoadHtmlType;
import com.spire.pdf.htmlconverter.qt.HtmlConverter;
import com.spire.pdf.htmlconverter.qt.Size;

public class ConvertHtmlStringToPdf {

    public static void main(String[] args) {

        //Specify the html string
        String htmlString = "<html>" +
                "<body>" +
                "<h2>An Unordered HTML List</h2>\n" +
                "<ul>" +
                " <li>Coffee</li>" +
                " <li>Tea</li>" +
                " <li>Milk</li>" +
                "</ul>" +
               "<h2>An Ordered HTML List</h2>" +
                "<ol>" +
                " <li>Coffee</li>" +
                " <li>Tea</li>" +
                " <li>Milk</li>" +
                "</ol>" +
                "</body>" +
                "</html>";

        //Specify the output file path
        String outputFile = "output/HtmlToPdf.pdf";

        //Specify the plugin path
        String pluginPath = "E:\\Products\\Java\\plugins-windows-x64";

        //Set plugin path
        HtmlConverter.setPluginPath(pluginPath);

        //Convert html string to PDF
        HtmlConverter.convert(htmlString, outputFile, true, 100000, new Size(600, 900), new PdfMargins(0), LoadHtmlType.Source_Code);
    }
}
