HTML to PDF API | RocketUtils

Why use an API for PDFs?

✅ No server bloat: Installing headless chrome on your own backend is heavy and complex. Offload it to us.
✅ Consistent Rendering: We use the latest Chromium engine to ensure modern CSS (Flexbox, Grid) renders perfectly.
✅ Security: Generating PDFs from user input can be risky. We sandboxing the execution for you.

Generate an Invoice

Send your raw HTML string, and get a PDF buffer back.

const invoiceHtml = \`
  
    
      Invoice #1024
      Billed to: John Doe
      
      Total: $49.00
    
  
\`;

const response = await fetch('https://rocketutils.dev/v1/pdf', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'x-api-key': 'YOUR_KEY'
  },
  body: JSON.stringify({ html: invoiceHtml })
});

const pdfBuffer = await response.arrayBuffer();
// Save or email this buffer!
