How to delete all of your Facebook messages, using a web browser or the Messenger mobile app

• You can't delete all your Facebook messages at once, but you can delete them one chat at a time.
• To delete a chat on Facebook, go to the chat settings and click Delete chat.
• To delete a chat on Messenger, swipe to the left, tap More and Delete.

Facebook Messenger is one of the most popular messaging apps in use today, in large part because it's available on nearly every platform.

But Facebook has never made it especially easy to manage your messages. For example, it took years for Facebook to give users the ability to delete an accidentally sent message from both the sender and receiver's app — and even then you only have 10 minutes to do so.

But what if you want to delete all your messages from Facebook Messenger? Here's what you need to know.

4. In the menu that pops up to the left, click Delete conversation.

5. In the pop-up window, confirm you want to do this by clicking Delete Chat.

6. Repeat this for every chat you want to remove.
