The Email Attachment Limit Problem
We've all been there: you've prepared the perfect file to sendβa high-resolution video presentation, a complete photo album from your latest project, or a comprehensive design packageβonly to see the dreaded error message: "Attachment size exceeds limit."
Most email providers impose strict attachment size limits. Gmail caps attachments at 25MB, Outlook at 20MB, and Yahoo at 25MB. When you're trying to send large files for work, creative projects, or personal use, these email attachment limits can bring your productivity to a grinding halt.
The good news? There are multiple effective ways to send large files over 25MB without the frustration of email limitations. In this comprehensive guide, we'll explore seven proven methods to share big files, comparing their speed, security, ease of use, and cost.

Method 1: Peer-to-Peer (P2P) File Transfer β Fastest & Most Secure
How It Works
Peer-to-peer file transfer creates a direct connection between your device and the recipient's device using WebRTC technology. Your files never pass through intermediate servers, making transfers faster and more private.
Best for: Sending large files quickly (videos, project folders, high-res images) when both parties are online simultaneously.
β Advantages
- Lightning-fast transfer speeds (often 3x faster than cloud services)
- Complete privacy with end-to-end encryption
- No file size limits (up to 10GB on most platforms)
- Files never stored on third-party servers
- No registration required
- Completely free
β Limitations
- Both sender and receiver must be online
- Requires modern web browser
- Link expires after transfer completes
- Not ideal for multiple recipients
How to use: Visit LargeFileTransfer.org, select your file, generate a share link, and send it to your recipient. They click the link and download instantlyβno uploads to servers, no waiting.
Method 2: Cloud Storage Services (Google Drive, Dropbox, OneDrive)
Cloud storage platforms let you upload files to their servers and share access via a link. This is one of the most popular methods to send large files because most people already have accounts.
Google Drive
Google Drive offers 15GB of free storage shared across Gmail, Google Photos, and Drive. It integrates seamlessly with Gmail, making it easy to send large files that exceed the email attachment limit.
Steps to send files via Google Drive:
- Upload your file to Google Drive
- Right-click the file and select "Get link"
- Set sharing permissions (anyone with link can view/download)
- Copy the link and share it via email or messaging
Dropbox
Dropbox provides 2GB of free storage and is known for reliable sync across devices. It's particularly popular among creative professionals for sharing design files and large media.
Microsoft OneDrive
OneDrive offers 5GB free and integrates perfectly with Microsoft Office. If you're already in the Microsoft ecosystem, this is a natural choice for file sharing.
β Advantages
- Recipients don't need accounts to download
- Files stay accessible until you delete them
- Good for sharing with multiple people
- Integration with email and productivity tools
- Automatic backup of your files
β Limitations
- Slower than direct transfer (upload + download required)
- Limited free storage space
- Files stored on third-party servers
- Upload time can be significant for large files
- Paid plans required for larger transfers
Method 3: WeTransfer β Simple & Quick
WeTransfer is a dedicated file transfer service designed specifically for sending large files. The free version allows files up to 2GB, while the paid WeTransfer Pro supports up to 200GB.
WeTransfer's key advantage is simplicity: upload your file, enter the recipient's email, and they receive a download link. Files are stored for 7 days (free) or up to 1 month (paid).
Best for: One-time file transfers when you don't need the file stored permanently.
Tip: WeTransfer is excellent for creative professionals sending portfolios, video files, or design packages to clients. However, for sensitive files, consider more secure alternatives with end-to-end encryption.
Method 4: FTP/SFTP β For Technical Users
File Transfer Protocol (FTP) and its secure variant SFTP are traditional methods used primarily by developers and IT professionals. This method requires setting up a server and using FTP client software like FileZilla or Cyberduck.
Best for: Regular large file transfers in business environments, backing up websites, or sharing files within technical teams.
Advantages: Unlimited file sizes, very fast transfer speeds, complete control over security and access.
Limitations: Requires technical knowledge, server setup and maintenance, not user-friendly for non-technical recipients.
Method 5: Physical Media (USB Drive, External Hard Drive)
Sometimes the old-fashioned way is the best way. For extremely large files (hundreds of GB or TB) or situations where internet access is limited, physical media remains a viable option.
The joke in tech circles is relevant here: "Never underestimate the bandwidth of a station wagon full of hard drives." For massive datasets, shipping a hard drive can actually be faster than uploading terabytes over the internet.
Best for: Extremely large datasets, backup archives, or situations with poor internet connectivity.
How to Choose the Right Method for Your Needs
Selecting the best way to send large files depends on your specific situation. Here's a decision framework:
Choose P2P Transfer (LargeFileTransfer.org) if:
- You need the fastest transfer speed possible

- You're in a business/enterprise environment
Security Considerations When Sending Large Files
When you send large files over the internet, security should always be a priority, especially for sensitive or confidential information. Here are key security factors to consider:
1. Encryption in Transit
Ensure files are encrypted while being transferred. Look for services using HTTPS (for web uploads) or end-to-end encryption (for P2P transfers). This prevents interception by third parties.
2. Encryption at Rest
If files are stored on servers (cloud storage), verify they're encrypted while stored. However, remember that the service provider may have access to encryption keys.
3. Password Protection
For sensitive files, use services that offer password protection. Share the password through a separate communication channel (text message, phone call) for added security.
4. Link Expiration
Choose services that allow you to set expiration dates on sharing links. This limits the window of vulnerability if a link falls into wrong hands.
5. File Deletion
For highly sensitive files, use services that don't store files on servers (like P2P transfer) or ensure you delete files from cloud storage after the recipient downloads them.
Security Best Practice: For confidential business documents, medical records, legal files, or financial information, prioritize end-to-end encrypted methods like P2P transfer or encrypted cloud storage with strong access controls.
Tips for Faster File Transfers
Want to speed up your large file transfers? Follow these proven tips:
- Use a wired connection: Ethernet is significantly faster and more stable than Wi-Fi for large uploads and downloads.
- Compress files when possible: ZIP files before sending to reduce size. This is especially effective for folders containing many small files.
- Transfer during off-peak hours: Internet speeds are often faster late at night or early morning when network congestion is low.
- Close unnecessary applications: Free up bandwidth by closing streaming services, auto-sync programs, and other bandwidth-heavy applications.
- Choose the right method: P2P transfers are generally 2-3x faster than cloud uploads because they eliminate the upload step to intermediate servers.
- Check your internet speed: Use a speed test to verify your upload speed. If it's unusually slow, contact your ISP.
Common Mistakes to Avoid
1. Not Checking File Size Before Sending
Verify your file size before choosing a method. A 5GB file won't work with WeTransfer's free tier or many email workarounds.
2. Sending Sensitive Files Without Encryption
Never send confidential information through unsecured methods. Always use encrypted transfer methods for sensitive data.
3. Forgetting to Compress Files
Compressing files can significantly reduce transfer times. A folder of documents might compress by 50% or more.
4. Not Verifying the Recipient Received the File
Always confirm the recipient successfully downloaded the file, especially for time-sensitive transfers.
5. Using Free Cloud Storage for Regular Large Transfers
If you frequently send large files, you'll quickly exhaust free storage quotas. Consider dedicated transfer solutions instead.
Conclusion: The Best Way to Send Large Files in 2025
