After converting, the file does not open anymore. Message: Something went wrong.

PDF file does not open after converting. The original file opens normally on the computer. It is 6MB and contains 8 pages.

Input file: Name: original.pdf Size: 6MB

Output file: Name: original.pdf Size: 1.65MB

PHP: 8.1

Error: after converting, the file does not open anymore. From failure.

My code:

<?php

namespace App\Classes;

use Exception;
use Spatie\PdfToImage\Pdf;

class FileHandler
{
    public function __construct()
    {
    }

    /**
     * @throws Exception
     */
    public function handle_file($file_path): void
    {
        $allowed_types = ['image/jpeg', 'image/png', 'application/pdf'];

        // Check if the file type is allowed
        $file_type = mime_content_type($file_path);
        if (!in_array($file_type, $allowed_types)) {
            throw new Exception("Invalid file type: {$file_type}");
        }

        // Reduce the quality of images
        if (str_starts_with($file_type, 'image/')) {
            $image = imagecreatefromstring(file_get_contents($file_path));
            imagejpeg($image, $file_path, 80);
        }

        // Reduce the size of files
        $max_size = 1024 * 1024; // 1 MB
        if (filesize($file_path) > $max_size) {
            $pdf = new Pdf($file_path);
            $pdf->setCompressionQuality(80);
            $pdf->setPage(1);
            $pdf->saveImage($file_path);
        }
    }
}

Short class, which takes the converted file and sends it to the server.
