There are two main tools for converting HTML to professional-quality PDF on Windows: Puppeteer (uses Chromium headless, ideal for complex CSS and web fonts) and wkhtmltopdf (standalone binary, no Node.js required).
const puppeteer = require('puppeteer');
async function convertToPdf({ html, output, format = 'A4', margin = {top:'15mm',bottom:'15mm',left:'15mm',right:'15mm'} }) {
const browser = await puppeteer.launch({ headless: 'new' });
const page = await browser.newPage();
await page.setContent(html, { waitUntil: 'networkidle0' });
await page.pdf({ path: output, format, margin, printBackground: true,
displayHeaderFooter: true,
footerTemplate: '<div style="font-size:9px;width:100%;text-align:center;color:#888">Page <span class="pageNumber"></span> of <span class="totalPages"></span></div>' });
await browser.close();
}
