How to Send Large Files via Email

Forget the limits on attachment size your provider allows

Sending a file as an email attachment is common practice to anyone. But not any file. You can only send a file that fits the size limits imposed by both the sender’s and the recipient’s email provider. When you create a movie project or a photo album, and want to share it with family or friends, you will want to use a large file transfer service. A file transfer service is a great solution if you need to send very big files that are gigabytes in size via email, when a regular email attachment wouldn’t work.

Using file transfer services helps you easily and securely share files or folders via email. All of these services have the same purpose, but they can differ greatly in functionality.

Check out this list of the most popular services that will allow you to send large files via email. We have also listed monthly limits on file size and number of recipients for free subscribers, and a description of all major features for each service.



  • Works with mobile devices.
  • AES-256 encryption.
  • Upgraded account encompasses a customized Filebox that can be used by others to send you large files.


  • Not very safe to use, as there is no scan for viruses.
  • Your account cannot be password-protected if it is free.
  • Free edition results in a slow file transfer speed.

The limitation of SendThisFile is that you can send large files via email for free with a lowered speed and a six-day download limit. Paid plans provide extra features and can be used to send and receive large branded files via a website or using an Outlook plugin.

SendThisFile combines safe file transfer and storage with the use of AES-256 encryption, but it does not perform scanning for viruses.

All you need to do is upload your file to the SendThisFile online interface and give the recipient’s email address.

There is no limit on size, so this service works well when you need to send large video files or photos.

FileMail uses cloud storage for your uploaded files. You provide an email address and a message, and your recipient gets alerted when the files are uploaded, and guided on how to download them and how to send large files over the internet.

Your Web-Based Email Service

How to send large files via email? Check out this article and you will learn all the secrets.

Most email services let you send large files via email storing them in the cloud. This is time-saving but generally is almost the same as sending a file as a regular email attachment. You may ask how to send large files over the internet. The answer is via the following services:

​Gmail: sends files up to 10GB using Google Drive

Outlook Mail on the Web: lets you send files up to 10GB using OneDrive.

Zoho Mail: lets you send files limited in size to your Zoho Docs account (also available with Google Drive, Dropbox, and other services).

Another new way to transfer big files online is FileWhopper - an online service that lets you transfer extremely large files online. Even 1TB! That’s quite impressive, but let’s see how it works. There are no Pro or premium plans, or a monthly subscription. The feature that makes FileWhopper stand out is that you pay a one-time fee depending on the size of the file you want to send.

FileWhopper supports multithreaded data transfer technology, so your files will be uploaded and downloaded at the highest possible speed.

FileWhopper is the perfect choice if you need to send a huge file just one time, or once in a while, to your friends or family.

    In general, when attaching files to an email, you can be reasonably sure that up to 10MB of attachments are okay. Some email servers may have smaller limits, but 10MB is generally the standard.
