How can high resolution images be efficiently compressed in PHP without compromising quality?

High resolution images can be efficiently compressed in PHP without compromising quality by using libraries like Imagick or GD to resize the images and save them in a more compressed format like JPEG. Additionally, optimizing the compression settings and quality level can help reduce the file size while maintaining image quality. 

// Load the original image
$image = new Imagick('original_image.jpg');

// Set compression quality
$image->setImageCompressionQuality(80);

// Resize the image
$image->resizeImage(800, 600, Imagick::FILTER_LANCZOS, 1);

// Save the compressed image
$image->writeImage('compressed_image.jpg');
