Sending Large Files by Email – Experts’ Best Advice

In today’s fast-paced digital world, the need to share large files via email has become a common challenge for individuals and businesses alike.

While email is a convenient means of communication, it was originally designed for sending text-based messages, and many email providers impose strict limits on the size of attachments.

These limits often range from 10 to 25 megabytes (MB), which can be insufficient when dealing with large documents, high-resolution images, videos, or other hefty files.

To address this issue, experts have devised a range of strategies to help you send large files by email efficiently and securely.

The Challenge of Sending Large Files

Before diving into expert advice, it’s important to understand the limitations and challenges associated with sending large files via email.

The email was originally conceived as a means of exchanging text-based messages. Consequently, most email providers have implemented attachment size limits to prevent email servers from becoming overwhelmed with oversized files.

While these limits are set to ensure the smooth operation of email services, they can pose significant obstacles when you need to transmit larger files.

This is where expert-recommended solutions come into play.

Expert Advice for Sending Large Files

Here are some tried-and-true methods recommended by experts for sending large files via email:

1. Use File Compression

File compression is a highly effective technique for reducing the size of your files before sending them as email attachments.

By compressing files into formats like ZIP or RAR, you can significantly decrease their size.

Numerous software tools are available for this purpose, both free and paid, making it a convenient solution.

2. Harness the Power of Cloud Storage Services

Cloud storage services such as Google Drive, Dropbox, and Microsoft OneDrive offer an excellent alternative to traditional email attachments.

Instead of attaching the file directly to the email, you can upload it to your chosen cloud storage provider and share a secure download link.

This approach not only bypasses email attachment size limits but also ensures that your recipient can access the file at their convenience.

3. Consider FTP (File Transfer Protocol)

For extremely large files or sensitive data that require the utmost security, experts often recommend using FTP (File Transfer Protocol). FTP enables secure, direct file transfers between your computer and the recipient’s server. While FTP may require some technical expertise to set up, it is a highly reliable method for sending large files.

4. Prioritize Email Encryption

Security is a paramount concern when sending large files, particularly when they contain sensitive or confidential information.

Email encryption ensures that your email and its attachments are protected during transit. Many email providers offer encryption options, and there are also third-party encryption tools available for added security.

5. Explore Online File Transfer Services

Numerous online services specialize in facilitating large file transfers. These services allow you to upload your file to their platform, generate a download link, and share it with your intended recipient. Popular options include WeTransfer and SendSpace, among others.

6. Verify Recipient’s Email Limits

Before attempting to send a large file via email, it is advisable to check the email service provider’s attachment size limits that your recipient uses.

Some email providers may have more generous attachment size limits, allowing you to send the file directly if it falls within their acceptable range.


To provide further clarity on the topic of sending large files by email, let’s address some frequently asked questions:

What is the maximum file size for email attachments?

The maximum file size for email attachments varies from one email service provider to another, but it typically falls within the range of 10 to 25 megabytes.

However, using alternative methods like cloud storage or file transfer services can bypass these limitations.

Are there any security concerns associated with sending large files?

Yes, security is a critical consideration when sending large files, particularly if they contain sensitive or confidential information.

Utilizing email encryption or secure file transfer methods like FTP can help mitigate these security risks.

Can I send large video files via email?

Sending large video files via email can be challenging due to their size.

It is generally recommended to use cloud storage or video-sharing platforms like YouTube or Vimeo to share videos with others.

What if the recipient is not familiar with cloud storage or file transfer services?

In cases where the recipient is not familiar with these services, it is essential to provide clear and concise instructions on how to access and download the file from the cloud storage or file transfer service you have used.

This ensures a seamless experience for the recipient.

Is there a limit to the number of files I can send using online file transfer services?

The limitations of online file transfer services can vary depending on the specific service provider and whether you are using a free or paid version.

It is advisable to review the terms and conditions of the service to understand any restrictions that may apply.

Can I password-protect large email attachments?

Yes, some email providers and compression tools offer the option to password-protect large email attachments, adding an extra layer of security to your files.


Sending large files via email does not have to be a daunting or frustrating task.

By following the expert advice outlined in this guide and considering alternative methods such as file compression, cloud storage, FTP, and encryption, you can ensure that your large files reach their destination securely and efficiently.

Communication with your recipient about the chosen file-sharing method can further enhance the overall experience and ensure a successful file transfer.
