Screen: Indicates that CSS rules are intended for on-screen viewing. Styles are optimized for digital screens, which typically include considerations like colors and layouts that look good on computer monitors.
Print: Instructs the browser to apply styles tailored for printed documents. This means the CSS rules are optimized for printing, ensuring readability and proper formatting when the HTML content is printed on physical media, like paper.

import {PdfDocument} from "@ironsoftware/ironpdf";

(async () => {
    // Create a PDF from an HTML string
    const pdf = await PdfDocument.fromHtml("<h1>Hello World</h1>");

    // Export the PDF to a file
    await pdf.saveAs("output.pdf");

    // Advanced Example with HTML Assets
    // Load external HTML assets: Images, CSS, and JavaScript.
    const htmlContentWithAssets = "<img src='icons/iron.png'>";
    const advancedPdf = await PdfDocument.fromHtml(htmlContentWithAssets);

    // Save the PDF with loaded assets
    await advancedPdf.saveAs("html-with-assets.pdf");
})();

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 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, 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.
