Unless you’re very sure you want to get rid of your Facebook account once and for all, we’d recommend going down the deactivation route.
Deactivating your account hides your profile from friends and search, but allows you to reactivate your account – complete with friends, updates, pictures and Likes – if you have any reason to return, simply by entering your login information.
Deleting your account is a major step, so think it through before you proceed. Facebook takes between 14 to 90 days to process account deletion requests, but once your account’s gone, it’s gone forever.
Before taking the plunge, it’s well worth downloading a copy of the data Facebook has on you.
To do this:
Click the downwards-pointing arrow in the top-right corner of the screen
Select Download a copy of your Facebook data
Or simply visit https://web.facebook.com/settings and the proceed by clicking on “Download a copy” of your information.
See the screenshot below:
Once that’s done, you’re ready to delete your account. Bear in mind, however, that your sent messages will continue to exist even when all other traces of your account are gone.
