                    <div class="preview">
                        <div id="previewHtmlContent"></div>
                    <div style="margin-bottom: 25px" class="input-group">
                        <input type="button" value="Show Preview" class="btn btn-info" id="previewHtml"><span id="error-message" class="error"></span>
                        <input type="button" value="Create PDF" class="btn btn-info hidden" id="convertHtmlToPDF">

Open convert.js file and add this complete code into it.

// Preview button click event
$(document).on('click', '#previewHtml', function() {

// Convert HTML to PDF
$(document).on('click', '#convertHtmlToPDF', function() {

// Show HTML preview function
function previewHTMLFile() {

    var filePath = $('#fileUpload').get(0).files[0];
    var fileContents;
    $("#fileUpload").css("border", "#a6a6a6 1px solid");
    if ($(filePath).length != 0) {
        var reader = new FileReader();
        reader.onload = function(e) {
            fileContents =;
    } else {
        $("#fileUpload").css("border", "#d96557 1px solid");

// Function to convert HTML to PDF
function converHTMLToPDF() {
    const { jsPDF } = window.jspdf;
    var pdf = new jsPDF('l', 'mm', [1200, 1210]);
    var pdfjs = document.querySelector('#previewHtmlContent');
    pdf.html(pdfjs, {
        callback: function(pdf) {
        x: 10,
        y: 10

Above code is the complete code to handle Preview function before generating HTML to PDF. Also, it handles when you hit to generate to PDF.


Suppose we have this pdf-format.html file which contains a simple HTML code structure.

<!DOCTYPE html>
<html lang="en">

    <title>HTML File Format</title>
    <meta charset="utf-8" />
