How to Email A Large File as Email Attachments Quickly


Nowadays, we often use email in our daily life. For small files, such as text files or photos, we can easily send them over the Internet as email attachments. However, when we need to send large files, the sending process becomes more troublesome.

Generally, emails are allowed to send files up to 20-25 Mb. Limitations and other difficulties prevent us from sharing large files via email. If you want to send any normal file whose size is not above 10 or 20 MB, you can easily send that file through email but if you are having a large file whose size can be above 100 MB or 500 MB then it is possible to use the methods we provided below.

Section 1 - How to Send Large Files via Email

Many email servers prevent you from sending large files over a certain size. When this problem happens, most users don't know how to email large files. Next, we will use Gmail as an example to introduce the method of sending large files.

The max attachment size of Gmail is 25 MB. If you have more than one attachment, they can't add up to more than 25 MB. If your file is greater than 25 MB, Gmail automatically adds a Google Drive link in the email instead of including it as an attachment.

Step 1. Open Gmail on your computer. Then log in to your Gmail account.

Step 2. At the top left, click the "Compose" button.


Step 3. If your file is smaller than 25MB, you can click the "Attach files" button to upload the file from your computer.

If your file is larger than 25MB, click the "Insert files using Drive" icon to select the files you want to attach. Then it will be sent as a Google Drive link.

Step 4. Type the text and the email address of the recipient. Click the "Send" button to send large files via email.


"You can also use other emails like Outlook and Yahoo. They also limit the size of files you can send. By default, Outlook does not send email messages with attachments that exceed 20 MB and Yahoo must not exceed 25MB in total file size."

Section 2 - Share Large Files via Cloud Storage Service

In addition to sending large files via email directly, you can also store files to be shared on cloud storage services such as Dropbox, Google Drive, or One Drive. You can share files with someone and notify them via email. Then they can click the link and download the file directly to their computer.
