<tbody>
<tr>
<td>Item 1</td>
<td>2</td>
<td>$50.00</td>
<td>$100.00</td>
</tr>
<!-- Add more rows for additional items -->
</tbody>
</table>
<div class="invoice-footer">
<p><strong>Total:</strong> $100.00</p>
</div>
</div>
</body>
</html>`
/* Load HTML Template To Generate PDF */
const pdf = await PdfDocument.fromHtml(invoiceHTML);
// Save the PDF document to the file system.
await pdf.saveAs("html-string-to-pdf.pdf");
This Node.js code uses the IronPDF library to convert an HTML invoice template into a PDF document. The HTML includes styling for a well-designed invoice with borders and is then saved to the file system as "html-string-to-pdf.pdf".

3.2. HTML File to PDF Documents
Converting HTML to PDF is essential for scenarios like dynamic report generation, invoicing, archiving, and document sharing. Tools like IronPDF in Node.js simplify this process for developers. In the below code example, we will create PDF label from HTML file.
Input HTML File
import {PdfDocument} from "@ironsoftware/ironpdf";
const pdf = await PdfDocument.fromFile("label.html");
// Save the PDF document to the file system.
await pdf.saveAs("html-file-to-pdf.pdf");
This JavaScript code employs the IronPDF library to seamlessly convert an HTML file, "label.html," into a PDF document. It then efficiently saves the generated PDF as "html-file-to-pdf.pdf" on the file system.
Output PDF File
3.3. URL To PDF File
URL to PDF conversion is vital for archiving web content, creating offline versions of web pages, and generating shareable documents. This process finds applications in digital documentation, research, and content preservation, ensuring accessibility beyond online environments. Below we will create convert URL to PDF format.
import {PdfDocument} from "@ironsoftware/ironpdf";
(async () => {
const pdf = await PdfDocument.fromUrl("https://www.wikipedia.org/");
await pdf.saveAs("pdf-from-url.pdf");
})();
This JavaScript code utilizes the IronPDF library to convert the content of the Wikipedia homepage (via its URL) into a PDF document. It asynchronously generates the PDF and saves it as "pdf-from-url.pdf" on the local file system.
Output PDF File
