Deleting your account, on the other hand, kills it completely: You won't be able to log back in to retrieve or view anything you've posted to Facebook, and if you want to use Facebook again, you would have to start from scratch.
Facebook recommends that you download a copy of the data you're published to the site before you delete your account. Open the settings menu on Facebook while logged in to your account by clicking on the gear icon in the upper left. Next, select Account Settings, and on the the General Account Settings page, look for Download a copy of your Facebook data and click the link. This will guide you through the process of downloading an archive of all your Facebook data.
The company doesn't make it immediately obvious as to how to delete your Facebook account, but to do so, log in to Facebook with your account, then visit Facebook's account deletion form to carry out the process.
Keep in mind: Once your Facebook account is gone, it's gone, so you should only delete your account if you're really, really sure that you won't use Facebook again.
