How to Send a 20GB File Online for Free (2026 Guide)
Trying to send a 20GB video, project folder, backup, or collection of files?
Email attachments are generally not designed for files this large, and many file-sharing services have upload limits that can interrupt your workflow.
The good news is that you can use a large-file sharing platform to upload your files and send someone a download link instead.
In this guide, we'll show you how to share a 20GB file online using OpenBeam, a temporary file-sharing platform that supports uploads of up to 100GB.
Why can't you send a 20GB file through email?
Most email services have attachment size limits far below 20GB.
For example, Gmail typically limits direct attachments to 25MB. Larger files can be shared using cloud storage links, but available storage and other limits may apply.
For large videos, ZIP archives, game builds, design assets, and project backups, a dedicated file-sharing service can be a more practical option.
How to send a 20GB file using OpenBeam
Step 1: Open OpenBeam
Visit https://openbeam.cloud in your web browser.
OpenBeam provides temporary file sharing and supports uploads up to 100GB per upload.
Step 2: Select your file
Choose the 20GB file you want to send.
This could be a video, ZIP archive, game build, design project, or another supported file type.
Step 3: Upload your file
Start uploading and wait for the transfer to complete.
The time required depends on your internet upload speed and connection stability.
For example, a 20GB file may take approximately:
| Upload speed | Approximate upload time |
|---|---|
| 10 Mbps | 4 hours 27 minutes |
| 25 Mbps | 1 hour 47 minutes |
| 50 Mbps | 53 minutes |
| 100 Mbps | 27 minutes |
These are theoretical estimates using decimal GB and Mbps, excluding network overhead and interruptions. Actual uploads may take longer.
Step 4: Copy your sharing link
Once the upload finishes, copy the generated sharing link.
You can send this link through email, a messaging app, or another communication channel.
Step 5: Share it with your recipient
The recipient can open the link and download the file while the share remains available.
Check the link's expiration and access settings before sending it.
Can you send an entire folder?
Yes. OpenBeam also supports folder uploads, making it useful for projects containing multiple files.
For example, a video editor could share a folder containing video clips, audio tracks, and other project assets.

Tips for sharing large files
Use a stable connection. Large uploads are more vulnerable to interruptions.
Check your upload speed. Upload bandwidth, not download bandwidth, is what matters when sending a file.
Verify the link. Make sure your recipient receives the correct URL and knows when it expires.
Protect sensitive files. Use appropriate access controls and avoid sharing confidential data without reviewing the service's security and privacy terms.
Final thoughts
Sending a 20GB file doesn't have to involve splitting it into dozens of attachments.
A large-file sharing platform lets you upload your file and share a link with the person who needs it.
