Is Jupiter Denser Than Saturn?

Jupiter is the largest planet in our solar system, but it's not the densest. And that's because as you add gas to Saturn, for example, try to turn it into Jupiter. It doesn't just grow in volume, that gas gets compressed. So adding a lot more mass to Jupiter also wouldn't make it much bigger. But it does get bigger though, right? It does get bigger, absolutely. There's also a maximum size to a gas planet.
