How to Download Your Facebook Messenger Messages

Meta lets you download a copy of your Messenger conversations as part of its “Download your information” tool. The process happens in the background and can take a while for long histories. Menu names change from time to time, so look for the closest match if a label differs.

To download Messenger messages, open Facebook’s Accounts Center, go to Your information and permissions, then Download your information. Choose your Facebook profile, select only Messages, pick Download to device, set the date range, choose JSON or HTML and tap Create files. Meta notifies you when the ZIP is ready.

Before you request the download

  • You need access to your Facebook account and may be asked to re-enter your password.
  • Select only Messages to keep the file small; a full Facebook download is much larger.
  • Choose JSON if you plan to import the messages into software, HTML if you want to read them in a browser. You can request both.
  • Lower media quality (or no media at all) makes the download much faster.

End-to-end encrypted chats

Meta has been rolling out end-to-end encryption for personal Messenger chats. Encrypted messages are protected so that Meta cannot read them, which also means they may not appear in the standard download.

Messenger offers a separate way to download encrypted chat history. In the Messenger app’s settings, open Privacy & safety, then End-to-end encrypted chats, and look for Message storage and an option to download your stored messages. You may need your secure storage PIN or recovery code.

If a recent conversation is missing from your Accounts Center download, an encrypted chat is the most likely reason.

What you get and how to open it

Meta delivers one or more ZIP files. Inside, messages are organised into folders, with one folder per conversation (usually within an inbox folder). Each conversation contains message files, named like message_1.json or message_1.html, and media folders if you included media.

  • HTML: double-click a conversation’s HTML file to read it in your browser.
  • JSON: structured text with sender names, timestamps and message content; best for importing into software.
  • Very long conversations are split across several numbered files.
  • If accented letters or emoji look garbled when you open a JSON file in a text editor, that is a known quirk of Meta’s encoding, not data loss. Tools built for these files decode it correctly.

Troubleshooting

Keep the download safe

Your download contains years of private conversations, including other people’s messages. Store it on a device you control, avoid leaving copies in shared folders, and delete old copies you no longer need.

Using it with Memory Clone

Memory Clone imports Messenger and Facebook ZIP, JSON and HTML downloads on your Windows PC, repairs Meta’s text encoding, and learns style separately for each relationship. See training an AI on Messenger messages for what happens next.

Frequently asked questions

How long does it take to download Messenger messages?

It depends on how much history and media you request. Messages-only downloads are usually much faster than full-account downloads with high-quality media.

Can I download only one Messenger conversation?

The Accounts Center tool downloads all messages in the date range you choose. You can then open just the conversation folder you need.

Can I download messages from a deactivated account?

You can download the messages that are in your own account, including conversations with people who later deactivated theirs.

Is JSON or HTML better?

JSON is better for importing into apps like Memory Clone; HTML is better for reading. Either can be imported.

Does downloading delete my messages?

No. Downloading creates a copy; your messages stay in Messenger.
