WordPress: Server Doesn't Have ImageMagick or GD Installed/Enabled

Error Explanation: The error message indicates that your server is missing ImageMagick or GD, two PHP libraries required by WordPress to handle image processing tasks like resizing, cropping, or generating thumbnails.

For closely related WordPress and image library topics, see Install ImageMagick or GD — Admin Guide, Server Does Not Have ImageMagick or GD — How to Check, and DB_COLLATE in WordPress.

Run the following PHP script to check for these libraries:

<?php

if (extension_loaded('gd')) {

    echo "GD is installed and enabled.\n";

} else {

    echo "GD is not installed.\n";

}



if (extension_loaded('imagick')) {

    echo "ImageMagick is installed and enabled.\n";

} else {

    echo "ImageMagick is not installed.\n";

}

?>

Save the file as check.php and access it via your browser or command line.

Install ImageMagick:

sudo apt update
sudo apt install imagemagick php-imagick -y
sudo systemctl restart apache2  # For Apache
sudo systemctl restart php7.x-fpm  # For Nginx with PHP-FPM

Install GD:

sudo apt update
sudo apt install php-gd -y
sudo systemctl restart apache2  # For Apache
sudo systemctl restart php7.x-fpm  # For Nginx with PHP-FPM

Verify Installation:

php -m | grep -E 'gd|imagick'

1. Enable GD and/or ImageMagick in php.ini:

extension=gd
extension=imagick

2. Restart the web server.
