    What is the HTML to PDF Converter?

    HTML to PDF is a client-side, browser-native document rendering tool that converts HTML code, inline CSS styles, HTML5 semantic elements, and web templates into crisp, print-ready PDF files. Designed for developers, accountants, and content creators, it features live iframe previews, customizable document headers, editable subtitles, custom timestamps, paper format controls (A4, Letter, Legal), and 100% local processing with zero server uploads.

    Key Features & Capabilities

    100% Client-Side Privacy

    All HTML parsing and PDF rendering happen locally in your web browser RAM. Sensitive invoices, customer agreements, and web pages never touch external servers.

    Live In-Browser Preview

    Real-time iframe viewer updates automatically as you type or edit HTML, allowing instant inspection of layout, spacing, and CSS formatting.

    Custom Headers & Dates

    Easily configure Header Titles, Subtitles, Date/Time stamps (or click 'Now'), and Footer subtext for official report generation.

    Paper & Margin Controls

    Select A4, Letter, or Legal paper dimensions in Portrait or Landscape orientation with custom margin presets.

    Clickable Links & Styling

    Preserves active hyper-links (<a href>), inline styles (style="..."), CSS tables, blockquotes, code pre blocks, and images.

    Dual Export Options

    Print/Save directly to PDF via your browser native print dialog, or download print-ready HTML files for archiving.

    Interactive HTML Scenario Explorer

    Select an HTML use case to inspect preview behavior, sample structure, and render specs:

    HTML Tag / FeatureExample UsagePDF Render ResultOptimization Tip
    <table><table border="1">...</table>Structured PDF TableUse border-collapse: collapse; for sharp gridlines.
    <a href="..."><a href="https://...">Link</a>Interactive HyperlinkURLs remain clickable inside the exported PDF file.

    Programmatic HTML to PDF Code Examples

    Automate HTML-to-PDF rendering in your backend framework or scripts:

    // Node.js - Convert HTML to PDF using Puppeteer
const fs = require('fs');
const puppeteer = require('puppeteer');

async function htmlToPdf(htmlString, outputPath = 'document.pdf') {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();

  // Load HTML string directly
  await page.setContent(htmlString, { waitUntil: 'networkidle0' });

  // Generate A4 PDF with background colors
  await page.pdf({
    path: outputPath,
    format: 'A4',
    printBackground: true,
    margin: { top: '16mm', bottom: '16mm', left: '16mm', right: '16mm' },
  });

  await browser.close();
  console.log('HTML successfully converted to PDF:', outputPath);
}

const htmlSample = '<h1>Invoice #1042</h1><p>Client-side HTML rendering.</p>';
htmlToPdf(htmlSample);
