Convert an HTML File to PDF

The HtmlConvert.convert() method has a different overload HtmlConvert.convert(String htmlString, String fileName, boolean enableJavaScript, int timeout, com.spire.pdf.htmlconverter.qt.Size pageSize, com.spire.pdf.graphics.PdfMargins margins, com.spire.pdf.htmlconverter.LoadHtmlType urlHtml), which takes HTML string as a parameter. We need first convert our HTML file to a HTML string, and then render the HTML sting as a PDF document. It is worth mentioning that both inline CSS style and internal CSS style are supported while converting.

Here is what the sample HTML file looks like in a Web browser.

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;
import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.IOException;
public class ConvertHtmlToPdf {
    public static void main(String[] args) throws IOException {
        //Invoke the custom method HtmlToString() to convert HTML file to string
        String htmlString = HtmlToString("C:\\Users\\Administrator\\Desktop\\Sample.html");
        //Specify the output file path
        String outputFile = "output/HtmlToPdf.pdf";
        //Specify the plugin path
        String pluginPath = "F:\\Libraries\\Plugin\\plugins-windows-x64";
        //Set plugin path
        HtmlConverter.setPluginPath(pluginPath);
        //Convert HTML string to PDF
        HtmlConverter.convert(htmlString, outputFile, true, 100000, new Size(700, 900), new PdfMargins(0), LoadHtmlType.Source_Code);
    }
    //Convert a HTML file to string
    public static String HtmlToString(String filePath) throws IOException {
        String path = filePath;
        File file = new File(path);
        FileReader fileReader = new FileReader(file);
        BufferedReader bufferedReader = new BufferedReader(fileReader);
        StringBuilder stringBuilder = new StringBuilder();
        String temp = "";
        while ((temp = bufferedReader.readLine()) != null) {
            stringBuilder.append(temp + "\n");
        }
        bufferedReader.close();
        String str = stringBuilder.toString();
        return str;
    }
}
