Overview

Html2PDF is a REST API that converts HTML markup or any public web URL into a downloadable PDF document. You send your HTML content or a URL, and the API returns a PDF binary or a link to download it. It is handy for generating reports, receipts, or printable pages directly from web content.

💡

Beginner Tip

If converting a URL, make sure the page is publicly accessible — the API fetches the URL from its own servers, so localhost or private network URLs will not work.

  }
});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

Common Errors & Troubleshooting

401 Unauthorized The apikey query parameter is missing or incorrect.
Append ?apikey=YOUR_API_KEY to every request URL.
Empty or corrupted PDF The target URL returned an error page or the HTML string was malformed.
Test the URL in a browser first to confirm it renders correctly, and validate your HTML before sending.
Timeout error The target URL took too long to load, exceeding the API render timeout.
Optimize the page being converted, or send raw HTML in the request body instead of a URL.
