    What is the Convertor to PDF Tool?

    Convertor to PDF is a browser-first, privacy-focused document conversion engine designed for developers, technical writers, and teams. It transforms Markdown READMEs, HTML templates, JSON payloads, CSV spreadsheets, source code snippets, XML, text, and images into print-ready PDF files. Featuring editable document headers, customizable subtitles (pasted-content), custom dates, table-of-contents generation, and adjustable margins—all executed locally without server uploads.

    Key Features & Capabilities

    100% Client-Side Privacy

    All file parsing, HTML rendering, and PDF layout generation happen inside your browser memory. Proprietary code, invoices, and docs remain private.

    Editable Subtitle & Timestamp

    Easily replace default header placeholders like pasted-content · date with custom document titles, version numbers, or custom dates.

    Multi-Format Source Support

    Seamlessly switch between Markdown READMEs, JSON, CSV tables, HTML templates, source code snippets, and SVG images with auto-detected formatting.

    Auto Table of Contents

    Markdown heading structures (# H1, ## H2) are parsed automatically into hyperlinked PDF bookmarks and outline navigation.

    Print & Page Specs

    Select A4, A3, Letter, or Legal paper dimensions in portrait or landscape orientations with adjustable margins, custom fonts, and watermark options.

    Clickable Links & Tables

    Markdown tables, CSV datasets, code pre blocks, and hyperlinked URLs retain full layout fidelity and interactivity in the output PDF.

    Programmatic PDF Conversion Examples

    Automate document-to-PDF rendering in your server or build pipeline:

    // Node.js - Render HTML / Markdown to PDF using Puppeteer
    const fs = require('fs');
    const puppeteer = require('puppeteer');
    
    async function convertToPdf(htmlContent, outputPath = 'document.pdf') {
      const browser = await puppeteer.launch();
      const page = await browser.newPage();
      
      await page.setContent(htmlContent, { waitUntil: 'networkidle0' });
      
      await page.pdf({
        path: outputPath,
        format: 'A4',
        margin: { top: '16mm', bottom: '16mm', left: '16mm', right: '16mm' },
        printBackground: true,
      });
    
      await browser.close();
      console.log('PDF rendered successfully:', outputPath);
    }
    
    const sampleHtml = '<h1>Project Documentation</h1><p>Exported via JsonifyTools</p>';
    convertToPdf(sampleHtml);

    Browser Client-Side PDF Rendering vs External Server APIs

    Client-Side Browser Engine (JsonifyTools)

    • Zero Data Exposure: Documents are processed in local RAM and never leave your web browser.
    • Instant Live Preview: Real-time iframe preview reflects text, header, and margin updates immediately.
    • 100% Free & Unlimited: No API rate limits, subscription paywalls, or document page caps.

    Cloud API / Server PDF Services

    • Privacy & Security Risk: Requires uploading sensitive files to remote third-party cloud servers.
    • Network Latency: Involves round-trip file uploads, remote rendering queues, and download delays.
