How do I renew my US passport?
Unfortunately, you cannot yet renew your passport online. I would guess this is for two reasons: Actual physical photos are needed for your new passport (which you need to purchase and provide on your own the government isn't going to do it for you). You need to provide your old passport as verification that it is authentic/nothing is wrong. Renew a Passport details the instructions you need to follow. It's not too bad luckily just fill out the form they provide, and mail it in with your current passport and new photos. (Make sure you get some kind of tracking number when you mail it in to ensure nothing bad happens).
