The visibility of your Facebook Reels depends on the audience you choose when sharing them. Here are the three options and who can see your reels in each case:

Public:

• Visible to anyone on or off Facebook, even without them having an account.
• People can use your original audio and create remixes of your reel (if you allow it).
• This is the default audience when you first create a reel.

Friends:

• Only your Facebook friends can see your reel.
• Your friends cannot remix your reel or use your original audio.

Friends Except...:

• You can choose specific friends to exclude from seeing your reel while still keeping it visible to the rest of your friends.
• Otherwise, it functions the same as the "Friends" option.
