What are some methods to display HTML files as PDF directly on a website?

One method to display HTML files as PDF directly on a website is to use a library like TCPDF or mpdf in PHP. These libraries allow you to convert HTML content to PDF format and display it on the website. By using these libraries, you can generate PDF files on the fly from HTML content and present them to the users without the need for external tools or plugins.

// Include the TCPDF library
require_once('tcpdf/tcpdf.php');

// Create new PDF document
$pdf = new TCPDF();

// Set document information
$pdf->SetCreator('Your Name');
$pdf->SetAuthor('Your Name');
$pdf->SetTitle('HTML to PDF');

// Add a page
$pdf->AddPage();

// Set HTML content
$html = '<h1>Hello, World!</h1>';
$pdf->writeHTML($html, true, false, true, false, '');

// Output PDF as a file
$pdf->Output('example.pdf', 'I');
