How to Export All Your Gmail Emails to a Backup File

I still remember the sinking feeling of watching a client’s Gmail account get suspended with zero warning — five years of client emails, invoices, and contracts, gone in an instant. It turned out fine, because I’d talked them into backing everything up two months earlier. Not everyone is that lucky. Whether you’re switching email providers, worried about a suspension, or just want a local copy of years of correspondence, exporting your Gmail is quicker than most people expect.

What You’ll Need Before You Start

This whole process runs through your browser, so there’s nothing to install. But a few things will make it go smoother:

A working internet connection, ideally not on metered data if your inbox is large
Enough free space on your computer (or in Google Drive) to hold the export — a heavy inbox with years of attachments can easily reach several gigabytes
About 5 minutes of active setup time, plus a wait of anywhere from an hour to a couple of days for Google to actually build the archive

📝 Note: You don’t need any third-party tools for this. Google’s own export tool, called Takeout, handles the entire job for free, and there’s no limit on how many times you can use it.

Step 1: Open Google Takeout

Head to takeout.google.com and sign in with the account you want to back up. If you’re juggling multiple Google accounts in the same browser, double-check the avatar in the top-right corner before you go any further — exporting the wrong inbox is a surprisingly common mix-up.

⚠️ Warning: Takeout only exports data for the account you’re currently signed into. If you manage several Gmail addresses, you’ll need to repeat this entire process separately for each one.

Step 2: Deselect Everything Except Mail

By default, Takeout has every single Google product checked — Photos, Drive, Calendar, all of it. Unless you actually want all of that, click Deselect all at the top of the product list first. It’s a lot faster than unchecking two dozen boxes one by one.

Scroll down until you find Mail and check its box. Right below it, you’ll see a pill-shaped button that says All Mail data included. Click it if you only want specific labels — say, just your Inbox and Sent folder rather than every promotional email you’ve ever received. Leave “Include all messages in Mail” checked if you genuinely want everything, then click OK.

💡 Tip: Drafts only come along for the ride if you tick Drafts as its own label in that filter menu. I’ve seen people assume “all messages” automatically covers drafts — it doesn’t always, so check the box explicitly if you need them.

Step 3: Choose Your File Format and Delivery Method

Scroll to the bottom of the page and click Next step. You’ll land on a screen with a few choices to make. Honestly, this part trips people up more than it should, so here’s the breakdown:

Option	What it does	Best for
Email download link	Google emails you a link when the archive is ready	Most people, smaller inboxes
Add to Drive / Dropbox / OneDrive / Box	Saves the archive directly into cloud storage	Large inboxes, skipping a manual download step

I’d recommend the email link method for most people — it’s simple, and you’re not eating into your Drive storage quota with a copy of data that’s already sitting in Gmail. Next, pick a file type: .zip works fine for almost everyone, while .tgz is really only useful if you’re on Linux and want a native archive format. Finally, set a maximum file size. If your export is bigger than the size you pick, Google just splits it into multiple files instead of one — so don’t stress too much over getting this number exactly right.

⚠️ Warning: If you choose “Add to Drive” for a large mailbox, remember that archive counts against your Drive storage. A backup in the tens of gigabytes can fill your quota fast — delete it from Drive once you’ve moved it somewhere permanent.

Step 4: Create the Export and Wait

Click Create export, and that’s it — Takeout goes to work in the background. You can close the tab; you don’t need to sit and watch a progress bar. For a modest inbox, the archive might be ready in under an hour. For something with a decade of history and thousands of attachments, it can take a day or two.

In my experience, exports for personal accounts under 5GB usually land within a few hours. Business accounts with heavy attachment use take noticeably longer, so plan accordingly if you’re working against a deadline like an account closure date.

📝 Note: Stay logged into your Google account while the export runs. Takeout occasionally re-prompts for two-factor authentication partway through a long-running job, and if you’re logged out, that can stall things.

Step 5: Download and Open Your Backup

Once it’s ready, you’ll get an email at the same Gmail address with a download link. That link is only valid for about a week, so don’t let it sit in your inbox — download the file and store it somewhere safe right away.

Inside the .zip, you’ll find a single file: usually something like “All mail Including Spam and Trash.mbox”. MBOX is a standard, widely supported mailbox format, but it’s not something you can just double-click and read like a PDF. To actually browse it, I’d install Mozilla Thunderbird (free) along with the ImportExportTools NG add-on, which lets you import the .mbox file and read every email exactly as it looked in Gmail, folders and all.

✅ Tip: Before you delete anything from Gmail itself, open the .mbox file in Thunderbird and spot-check a handful of old emails, especially ones with attachments. This takes two minutes and confirms your backup actually worked.

Pro Tips for a Cleaner Backup

Run a search first — try queries like has:attachment larger:10M in Gmail’s search bar to see roughly what’s bulking up your export before you commit to it.
Set up IMAP as a second safety net. Go to Settings → See all settings → Forwarding and POP/IMAP, enable IMAP, then sync the account into Thunderbird. That gives you a live, continuously updated local copy alongside your one-time Takeout archive.
If you sent anything with Confidential Mode, know that it exports as a placeholder, not the actual message body — the real content stays on Google’s servers until it expires.
For just a handful of important emails rather than the whole inbox, you can skip Takeout entirely — forward them to yourself as attachments, which downloads as individual .eml files you can open in almost any email client.

Common Mistakes to Avoid

Exporting the wrong account. Always check the avatar in the top-right corner of Takeout before you start.
Letting the download link expire. You get about a week before it stops working, and you’d have to run the whole export again.
Forgetting Chats or Drafts. These don’t always come bundled with “all messages” — check the label filter if you need them.
Deleting Gmail data before verifying the backup opens correctly. Always open the .mbox file in Thunderbird first.

Quick Recap

Sign into Google Takeout, deselect everything but Mail, choose your format and delivery method, then create the export and wait for the download link. Open the resulting .mbox file in Thunderbird to browse or import your emails.

Wrapping Up

That’s really all there is to it. You now have a full, offline copy of your Gmail account sitting safely on your hard drive, and you know exactly how to open and verify it. Once you’ve confirmed the backup is solid, you’re free to switch providers, clean out your inbox, or close the account altogether without worrying about losing anything important. If you end up managing more than one Gmail address, just remember to repeat the process for each one separately.
