Are there any best practices for optimizing the performance of PDF to PNG conversion in PHP?

PDF to PNG conversion in PHP can be optimized by using a library like Imagick, which provides better performance compared to other methods. To further enhance performance, it is recommended to adjust the resolution and quality settings based on the requirements of the output PNG image. 

// Load the PDF file
$pdf = new Imagick('input.pdf');

// Set the resolution and quality settings
$pdf->setResolution(300, 300);
$pdf->setImageFormat('png');
$pdf->setImageCompressionQuality(90);

// Convert each page of the PDF to PNG
foreach ($pdf as $page) {
    $page->writeImage('output_' . $pdf->getIteratorIndex() . '.png');
}

// Clear resources
$pdf->clear();
$pdf->destroy();
