Use CSS to enhance the website’s visual appeal and ensure responsiveness.

CSS Code:

cssCopy codebody {
    font-family: Arial, sans-serif;
    margin: 0;
    padding: 0;
    background-color: #f4f4f4;
    color: #333;
}

header {
    text-align: center;
    background-color: #007BFF;
    color: white;

3. PHP: Implementing the Backend Logic

The PHP script processes uploaded JPG files, converts them to a single PDF, and provides a downloadable link.

PHP Code (`convert.php`):

phpCopy code<?php
if ($_SERVER['REQUEST_METHOD'] == 'POST' && isset($_FILES['images'])) {
    require('fpdf/fpdf.php');

    $pdf = new FPDF();
    $uploadDir = 'uploads/';

    // Handle uploaded files
    foreach ($_FILES['images']['tmp_name'] as $key => $tmpName) {
        $fileType = mime_content_type($tmpName);
        if ($fileType == 'image/jpeg') {
            $pdf->AddPage();
            $pdf->Image($tmpName, 10, 10, 190);
        } else {
            echo "Invalid file type: $fileType";
            exit;
        }
    }

    // Save the PDF
    $outputFile = $uploadDir . 'converted_' . time() . '.pdf';
    $pdf->Output('F', $outputFile);

    echo "Conversion successful! <a href='$outputFile' download>Download PDF</a>";
}
?>
