How to Backup Gmail Messages Locally

This guide shows you how to create a local backup of your Gmail messages on your own computer, so you have a copy independent of Google’s servers. You’ll learn the built-in Google Takeout method and a direct email client approach, with clear steps for both. No special software is required for the primary method, just a Google account and a web browser.

What You’ll Need

A Google account with Gmail enabled
A web browser (Chrome, Firefox, Safari, Edge)
Enough free disk space on your computer (Gmail messages are small, but attachments can add up; check your storage usage in Gmail settings)
Optional: An email client like Thunderbird or Outlook if you prefer the direct download method

Step-by-Step

Method 1: Using Google Takeout (Recommended)

Go to Google Takeout. Open your browser and navigate to takeout.google.com. Sign in with the Google account that has the Gmail messages you want to back up.
Deselect all services. On the main page, click Deselect all to avoid downloading unnecessary data from other Google services.
Select Mail. Scroll down and check the box next to Mail. You can click the checkbox itself to select all mail, or click the arrow on the right to expand options and choose specific labels (e.g., Inbox, Sent, or a custom label).
Choose the format and frequency. Click All Mail data included to open the format settings. Choose Export once from the frequency dropdown. For file type, select .zip (or .tgz if you prefer). Set the file size to a reasonable value like 10 GB or 50 GB; Google will split the archive if it exceeds this. Click OK.
Create the export. Scroll down and click Next step. Choose a delivery method (usually Send download link via email). Click Create export.
Wait for the export to complete. Google will prepare your files. This can take from minutes to a few hours, depending on the size of your mailbox. You’ll receive an email when it’s ready.
Download the archive. When the email arrives, click the Download your files button. You may be asked to sign in again. The download will start as a .zip file (or multiple parts).
Extract and store. Once downloaded, extract the .zip file. Inside, you’ll find a folder named Mail containing .mbox files for each label. Store these files in a safe location, ideally on an external drive or cloud storage (not just the same computer).

Method 2: Using an Email Client (Thunderbird)

This method downloads your messages directly to your computer using IMAP.

Install Thunderbird. Download and install Mozilla Thunderbird from the official website.
Add your Gmail account. Open Thunderbird and click Set Up an Existing Email Address. Enter your full Gmail address and password (or an app password if you have 2FA enabled).
Wait for initial sync. Thunderbird will start downloading your messages. This may take a while for large mailboxes. You’ll see a progress indicator at the bottom.
Back up the profile folder. Once synced, your messages are stored locally in Thunderbird’s profile folder. To back them up, close Thunderbird and copy the entire profile folder (usually located at C:\Users\[YourUsername]\AppData\Roaming\Thunderbird\Profiles\[random].default-release on Windows, or ~/Library/Thunderbird/Profiles/ on macOS, or ~/.thunderbird/ on Linux).
Alternatively, export as mbox. If you prefer a single file, install the ImportExportTools NG add-on. Then right-click on your Gmail account in Thunderbird, choose ImportExportTools NG > Export all messages of the folder and save as an .mbox file.

Common Mistakes

Not selecting “All Mail” – If you only select “Inbox”, you miss sent, drafts, and archived messages. Use “All Mail” or select every label you need.
Forgetting about attachments – Google Takeout includes attachments in the .mbox file, but the file size can be huge. Check your storage usage first and plan accordingly.
Storing the backup only on the same computer – If your hard drive fails, you lose both the original and the backup. Use an external drive or a second cloud service.
Deleting Gmail messages after backup – A backup is not a sync; it’s a snapshot. If you delete messages in Gmail after the backup, they won’t be removed from the backup, but they also won’t be added to it. The backup is only as current as the export date.
Using IMAP without local storage – Some email clients (like Outlook) may only cache messages, not store them fully. Ensure your client is configured to keep a local copy (e.g., “Keep messages on this computer” in Outlook).

Tips

Back up regularly – Set a reminder to do a Takeout export every 3-6 months, depending on how much email you receive.
Use two-factor authentication – When using an email client, generate an “App Password” from your Google account settings instead of using your main password. This is more secure and avoids sync issues.
Test your backup – After downloading, try opening the .mbox file in a text editor (it’s a plain text format) or import it into a fresh Thunderbird profile to verify it’s readable.
Compress the backup – If you have many large attachments, the .mbox files can be compressed further with a tool like 7-Zip to save space.
Label your exports – Name your backup files with the date (e.g., gmail-backup-2025-04-01.zip) so you know which is the latest.

Troubleshooting

Download link expires – Takeout links expire after a week. If yours expires, go back to takeout.google.com and click “Manage exports” to re-send the link.
Export is stuck at “In progress” – Large mailboxes can take up to 48 hours. If it’s longer, check your email for a notification. Sometimes, re-creating the export helps.
The .mbox file is huge – If the file exceeds 10 GB, it may be hard to handle. Use the “split by size” option in Takeout or export only specific labels (e.g., Inbox and Sent separately).
Thunderbird doesn’t sync all messages – Make sure you haven’t set a “sync all messages” limit. Go to Account Settings > Synchronization & Storage and set “Keep messages for all folders on this computer” or adjust the limit to “All”.
Can’t open the .mbox file – .mbox is a standard format but not all email clients import it directly. Use Thunderbird with the ImportExportTools add-on, or use a dedicated tool like maildir converter.
App password not working – Ensure you’ve enabled 2FA first. Then go to Google Account > Security > App passwords, generate a new one, and use it immediately. If it still fails, revoke and regenerate.

Frequently Asked Questions

Does Google Takeout include attachments?

Yes, the .mbox files from Takeout include all message content, including attachments, embedded images, and headers.

Can I restore a backup into Gmail?

Yes, you can import .mbox files into Gmail using the built-in import tool (Settings > Accounts > Import). However, this may not preserve labels perfectly; it will create a new label for each imported folder.

Will my backup include drafts and spam?

Takeout includes all labels, including Drafts, Spam, and Trash, unless you specifically exclude them. By default, “All Mail” includes everything except Spam and Trash, but you can select those labels individually.

How long does a Takeout export take?

It depends on the size of your mailbox. Small accounts (a few hundred MB) may take minutes, while large accounts (10+ GB) can take several hours or even a day.

Is there a limit to how many times I can run Takeout?

No, you can run it as often as you like. However, Google may rate-limit exports if you do it excessively in a short period.

Can I use Google Vault instead of Takeout?

Google Vault is for enterprise accounts with admin privileges. For personal accounts, Takeout is the only official way to export your data.
