Are there any best practices for handling image conversion in PHP?

When handling image conversion in PHP, it is important to ensure that the input and output formats are supported, and that the conversion process does not degrade the image quality. One common approach is to use the GD library, which is a built-in PHP extension that provides functions for image manipulation and conversion.

// Example code snippet using GD library for image conversion
$inputImage = 'input.jpg';
$outputImage = 'output.png';

// Load input image
$source = imagecreatefromjpeg($inputImage);

// Save output image
imagepng($source, $outputImage);

// Free memory
imagedestroy($source);
