How to Send Large Files via Email?

Email has become a ubiquitous tool for communication, allowing us to send messages, documents, and files with ease. However, when it comes to sending large files, many email services impose a limit on the size of attachments. This can be a significant hurdle for those who need to share large files such as high-resolution photos, videos, or large documents. But fear not, there are several ways to send large files via email, and this guide will walk you through each step.

Understanding Email Attachment Limits

Before we delve into how to send large files via email, it's important to understand why there are limits in the first place. Most email services, including Gmail, Yahoo, and Outlook, have a limit on the size of attachments you can send. This is primarily to prevent their servers from being overwhelmed with large amounts of data. Additionally, it also helps to protect users from potential security threats associated with large files.

For example, Gmail allows you to send attachments up to 25MB in size. If your file is larger than this, you'll need to use an alternative method to send it. Similarly, Yahoo Mail has a limit of 25MB, while Outlook limits attachments to 20MB. It's important to keep these limits in mind when trying to send large files via email.

Methods to Send Large Files via Email

Now that we understand why there are limits on email attachments, let's explore the different methods you can use to send large files via email. There are several options available, each with its own set of advantages and disadvantages. The method you choose will depend on the size of the file, your recipient's technical capabilities, and your own preferences.

Here are some of the most common methods:

1. Using Cloud Storage Services

Cloud storage services like Google Drive, Dropbox, and OneDrive allow you to upload large files to the cloud and then share a link to the file via email. This is a popular method because it bypasses the email attachment size limit altogether. The recipient can then download the file directly from the cloud storage service at their convenience.

Most of these services offer a certain amount of storage space for free, and you can purchase more if needed. They also offer robust security features to protect your files. However, keep in mind that the recipient will need to have an account with the same service to download the file.

2. Using File Compression Software

File compression software, such as WinZip or 7-Zip, can reduce the size of your file, making it small enough to send as an email attachment. This method is particularly useful for sending multiple files or folders, as the software can compress them into a single, smaller file.

However, the recipient will need to have the same software to decompress the file and access its contents. Additionally, while compression can significantly reduce the size of some files, it may not be enough for very large files.

3. Using File Transfer Services

File transfer services like WeTransfer or SendAnywhere allow you to upload your file to their servers and then send a link to the file via email. These services are designed specifically for sending large files, and they often allow you to send much larger files than cloud storage services.

Most file transfer services offer a free tier with a maximum file size limit, and you can pay for a premium tier if you need to send larger files. However, these services often do not offer the same level of security as cloud storage services, so they may not be suitable for sending sensitive files.

Choosing the Right Method for You

When choosing a method to send large files via email, consider the size of the file, the technical capabilities of your recipient, and the importance of security. If you're sending a very large file, a file transfer service may be your best bet. If security is a concern, a cloud storage service may be more appropriate. And if you're sending multiple files or folders, file compression software could be the most convenient option.

Remember, the goal is not just to send the file, but to ensure that your recipient can easily receive and access it. By understanding the different methods available and their pros and cons, you can choose the best method for your needs.


Sending large files via email can be a challenge, but with the right tools and knowledge, it's entirely possible. Whether you choose to use a cloud storage service, file compression software, or a file transfer service, each method has its own advantages and can help you overcome the limitations of email attachment sizes.

Remember to always consider the size of your file, the capabilities of your recipient, and the level of security you need when choosing a method. With these considerations in mind, you'll be well-equipped to send large files via email with ease.
