    await pdf.saveAs("output.pdf");

    // Advanced Example with HTML Assets

    const htmlContentWithAssets = "<img src='icons/iron.png'>";

HTML String to PDF

Use the fromHtml method to convert HTML strings and files into PDF documents. The resulting PDF document should be identical to the one generated by the print feature of the Google Chrome browser. IronPDF utilizes the Chrome engine for rendering HTML to PDF documents, ensuring the same output when using the same configuration as Google Chrome.

In addition to its rendering capabilities, IronPDF offers a wealth of features for manipulating PDF documents. It seamlessly combines rendering and manipulation into a set of new features. For example, consider the HTML stamping feature of IronPDF, which involves rendering HTML and merging the resulting PDF with the main HTML content to produce a final document with HTML stamps either behind or in front of the primary content.
