Which one should you use?
While dire au revoir is used for standard departures where you expect to see the person again, adieu implies a much more permanent or final separation, translating to 'farewell'. Other options include À bientôt for 'see you soon' and À plus, which is a shortened form of à plus tard meaning 'see you later'. Depending on the time of day, you might say bonne soirée for 'good evening' or bonne journée for 'have a good day'.
Is there a formal and an informal way to say it?
Salut is an informal way to say both 'hi' and 'bye', suited for friends and peers. Ciao, borrowed from Italian, is also used as a casual way to say goodbye. In contrast, adieu is a more formal and slightly dramatic way to say goodbye, implying a final farewell.
How does it change in a sentence?
When used as a standalone greeting or farewell, the infinitive dire is dropped and you simply say au revoir.
When do people say it?
When saying goodbye, French speakers often choose their phrase based on the expected duration of the separation or the time of day. For instance, one might use bonne soirée if leaving someone in the evening or bonne journée during the day.
