Disable Unwanted Image Sizes Generation in WordPress
Do you know that every single time you upload an file to your WordPress size. The WordPress will automatically generate a tons of images without your notice? If you are notice about it and yes, I’ve came over with solutions.
To stop WordPress from generating the Images, you need to use a child theme and add it to your child theme function.php file.
// Disable WordPress and Woocommerce Image Sizes
function disable_wp_image_sizes( $sizes ) {
unset( $sizes['thumbnail'] );
unset( $sizes['medium'] );
unset( $sizes['medium_large'] );
unset( $sizes['large'] );
unset( $sizes['1536x1536']);
unset( $sizes['2048x2048']);
// WooCommerce Image Size
unset( $sizes['woocommerce_thumbnail'] );
unset( $sizes['woocommerce_single'] );
unset( $sizes['woocommerce_gallery_thumbnail'] );
unset( $sizes['shop_catalog'] );
unset( $sizes['shop_single'] );
unset( $sizes['shop_thumbnail'] );
return $sizes;
}
add_filter('intermediate_image_sizes_advanced', 'disable_wp_image_sizes');
// Disable Scale Image Sizes
add_filter('big_image_size_threshold', '__return_false');
// Disable Other Image Sizes
function disable_wp_other_image_sizes() {
remove_image_size('post-thumbnail'); // disable images added via set_post_thumbnail_size()
remove_image_size('another-size'); // disable any other added image sizes
}
add_action('init', 'disable_wp_other_image_sizes');
Once you have place the code to the function.php, don’t forget to save it. It will works immediately, I have test it with latest version of WordPress 5.4.
