What are the advantages and disadvantages of using the imagepng() function in PHP for saving images?

The imagepng() function in PHP is used to save an image as a PNG file. One advantage of using this function is that it allows for easy conversion of images to the PNG format. However, a disadvantage is that it may result in larger file sizes compared to other image formats like JPEG. Additionally, the image quality may be slightly lower when saving as a PNG. 

// Sample code snippet demonstrating the use of imagepng() function
$source_image = imagecreatefromjpeg('input.jpg');
$output_file = 'output.png';

// Save the image as a PNG file
imagepng($source_image, $output_file);

// Free up memory
imagedestroy($source_image);
