/*change thumbnail quality in woocommerce*/
    add_filter( 'woocommerce_get_image_size_gallery_thumbnail', function( $size ) {
        return array(
            'width' => 600, //change this to edit thumbnail witdth - default 150px
            'height' => 600, //change this to edit thumbnail height - default 150px
            'crop' => 0,
        );
    } );

That’s wonderful ?? Thank you for sharing the solution with the community.
