   Example

   In a theme’s functions.php file:

   
   function wpdocs_remove_plugin_image_sizes() {
   	remove_image_size( 'image-name' );
   }
   add_action('init', 'wpdocs_remove_plugin_image_sizes');
   

   You could combine this with the add_image_size function in your theme.

   
   function wpdocs_remove_then_add_image_sizes() {
   	remove_image_size( 'image-name' );
   	add_image_size( 'image-name', 200, 200, true );
   }
   add_action('init', 'wpdocs_remove_then_add_image_sizes');
   

To remove all the image sizes keeping only the default WordPress image sizes –

function remove_extra_image_sizes() {
    foreach ( get_intermediate_image_sizes() as $size ) {
        if ( !in_array( $size, array( 'thumbnail', 'medium', 'medium_large', 'large' ) ) ) {
            remove_image_size( $size );
        }
    }
}

add_action('init', 'remove_extra_image_sizes');
