What is the Gmail attachment size limit?

The attachment size limit in Gmail is 25 MB per email. It doesn’t matter how many files you add. As long as the total size of your attachments stays under the 25 MB restriction set by Gmail.

For example, you could you attach:

  • One 25 MB file
  • Two 12.5 MB files
  • Ten 2.5 MB files and so on

That’s the theory anyways.

Well, the thing is, in actuality, the limit of 25 MB incorporates both your file as well as an encoded duplicate of it. Consequently, the maximum size for a file in Gmail is actually only 12.5 MB, which, truth be told, isn’t all that much.

If you take a quick look at other email service providers, you’ll see that they all have similar restrictions.

Here are the file size limits of the most popular email service providers:

  • Gmail: 25 MB
  • Yahoo: 25 MB
  • AOL: 25 MB
  • Outlook: 20 MB
  • Hotmail: 10 MB

But why is there a maximum attachment size to begin with? ostly fFor safety and storage reasons. Your inbox and the Gmail servers are not designed to process large files.

How to bypass the attachment size limit in Gmail?

Does that mean you can’t send large emails from your Gmail inbox? Not quite. We’ve discovered that there are (at least) 3 ways to get around the Gmail attachment size limit.

Option 1: Send large files with Google Drive

This is (by far) the best option. You can use Google’s cloud storage solution to effortlessly share large files with other people. Google Drive is easy to use and it works great with Gmail.

Step 1: Open your Google Drive.

Step 2: Click on New.

In some cases, Google will ask you to authorize your recipient to access the file. You can choose grant them access as:

  • Viewer (they can view the file)
  • Commenter (they can view and comment the file)
  • Editor (they can view, comment and edit the file)

Select a role. And press send again.

That’s it. You’ve just sent an email with an attachment larger than 25 MB using Google Drive, the cloud storage service associated with your Gmail account.

Option 2: Compress your files

You can’t increase the attachment size limit in Gmail. But you can reduce the size of your files. To do that, you’ll need to compress them into a zip folder. Here’s how to do it.

Step 1: Open your file explorer.

Step 2: Find the files you want to send and select them.

Step 3: Right-click on your documents. From there select Send to and then Compressed folder (on Windows) or Compress (on Mac).

This will significantly decrease the size of your files.

Step 4: Compose a new email in Gmail. And click on Attach files (the small paperclip icon below your message).

Step 5: Find your zipped file. And click Open to attach them to your email.

Step 6: Press Send.

And voilà. Your recipients will receive a compressed version of your files. They can easily unzip those files to return them to their original size.

Option 3: Use a file-sharing service

Email is not always the best way to send large files. But you have other options. Over the last few years, a lot of free tools have popped up across the internet. And some of them are specifically designed to share heavy files.

You can use large file-sending services such as WeTransfer, Dropbox or TransferNow to bypass the Gmail attachment size limit and send a 4K video or a massive PDF to your family or colleagues. All that in a few clicks.

To do that, simply upload your file on one of these platforms. And click send. Your recipient will receive a link. All they need to do is to click on that link. And they can then download and retrieve your file. Easy, right?

But this solution is not perfect. Some of these tools have size limits of their own. For example, WeTransfer comes with a 2 GB size limitation. Which might still not be enough if you want to send multiple large files.

Additionally, some of these platforms are less secure than others. This might be a problem. Especially if you’re sending sensitive information. To protect your data, you may want to encrypt your files.
