You can read HTML content and convert it to PDF using jsPDF:

var doc = new jsPDF();

var elementHTML = document.getElementById('content').innerHTML;

doc.fromHTML(elementHTML, 15, 15);'myDocument.pdf');

Custom Styles and Page Breaks

jsPDF allows you to customize the style of your PDF:

Puppeteer: Advanced HTML to PDF Conversion

Puppeteer is a powerful Node.js library that provides a high-level API to control Chrome or Chromium over the DevTools Protocol. It’s perfect for generating PDFs from HTML, especially for complex pages or when you need more control over the rendering process.

const puppeteer = require('puppeteer'); (async () => {

const browser = awaitpuppeteer.launch();

const page = await browser.newPage();

awaitpage.goto('', {

waitUntil: 'networkidle2'


await page.pdf({

path: 'example.pdf', format: 'A4'


await browser.close();

}) ();

This code launches a headless browser, navigates to a webpage, and saves it as a PDF file.

Advanced Customization

Puppeteer offers advanced customization options for PDF generation, such as setting page margins, format, and scale:

await page.pdf({

path: 'example.pdf',

format: 'A4',

margin: {

top: '20px',
