    You can exclude certain image types from images sizes, like gifs

    function wpdocs_disable_upload_sizes( $sizes, $image_meta ) {
        // Get filetype data.
        $filetype = wp_check_filetype( $image_meta['file'] );
        $exclude_file_types = array(
        // Check if file type is on exclude list 
        if ( in_array( $filetype['type'], $exclude_file_types ) ) {
            $sizes = array();
        // Return sizes you want to create from image (None if image is gif.)
        return $sizes;
    add_filter( 'intermediate_image_sizes_advanced', 'wpdocs_disable_upload_sizes', 10, 2 );
