How to Convert Markdown to PDF in Node.js (with one API call)

Stop wrestling with Puppeteer and LaTeX. Here is the simplest way to convert Markdown to PDF, DOCX, or HTML using a single API call from Node.js.

The problem with converting Markdown to PDF

Converting Markdown to PDF in Node.js usually means one of three painful paths: Puppeteer (memory-hungry, breaks on serverless), LaTeX (fragile dependencies), or pandoc (needs a system install). None scale cleanly in modern deploy targets like Vercel, Cloudflare Workers, or AWS Lambda.

The simple solution

**MarkdownPDF** is a single API endpoint that handles the conversion. No browser, no LaTeX, no system dependencies — just an HTTP call.

Quick example

const response = await fetch('https://markdownpdf.p.rapidapi.com/convert', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'X-RapidAPI-Key': process.env.RAPIDAPI_KEY,
  },
  body: JSON.stringify({
    markdown: '# Hello\n\nThis is **markdown**.',
    format: 'pdf',
    theme: 'modern'
  })
});

const pdf = await response.arrayBuffer();

That is the whole integration. Sub-100ms response time, zero dependencies in your bundle.

Five themes, three formats

• **Themes:** modern, classic, minimal, terminal, elegant
• **Formats:** PDF, DOCX, HTML
• **Page sizes:** A4, US Letter, Legal
• **Extras:** custom headers/footers, table of contents, syntax-highlighted code blocks

Common use cases

• **Invoicing:** generate PDF invoices from markdown templates
• **Reports:** turn markdown reports into branded PDFs
• **Documentation exports:** ship docs as downloadable PDF or DOCX
• **Receipts and confirmations:** transactional documents at scale
