How to Transfer a 20 GB File Online - 3 Steps
Step 1
Open FileSendZone in your browser on the device with the 20 GB file. Click 'Add Files' to select the file, or 'Add Folder' to send an entire folder.
Step 2
A link and QR code appear on screen right away. Copy the link and share it however you like - or let the recipient scan the QR code with their camera.
Step 3
The recipient opens the link and the 20 GB file downloads directly from your device. No server upload needed on your end. Transfer starts immediately when they open the link.
Built for sharing without friction
20 GB - Free, No Exceptions
At 20 GB, every major competitor either charges you or tells you the file is too big. FileSendZone does neither. Send 20 GB free, same as any other file size.
No Server in the Middle
Uploading 20 GB to a server before someone can download it would take a very long time. FileSendZone sends directly between devices. Both sides start moving at the same time.
Completely Free - No Strings
FileSendZone does not have a paid plan. There is nothing to upgrade to. 20 GB transfers are free now and will stay free.
No Account, No App to Install
Open FileSendZone in any browser, pick your 20 GB file, and get a link. No email, no password, no app download needed on either side.
Private - Nothing Left on a Server
Most tools that handle 20 GB store your file on their servers for days. That file sits there accessible to anyone who gets the link. FileSendZone stores nothing. Your file goes from your device to theirs and disappears.
Any Device Can Handle It
Send 20 GB from Windows, Mac, iPhone, or Android. The person receiving can be on any device. The browser does all the work.
Questions? Answered.
Can I transfer a 20 GB file online for free?
Yes. FileSendZone is free for 20 GB transfers. At this size, most other services require a paid plan. FileSendZone has no paid plans and no size limit.
What kind of files are 20 GB?
Multiple 4K video clips, a full wedding video project, a large game backup, a VM image, a full hard drive backup folder - these often reach 20 GB. FileSendZone sends all of them.
How long does a 20 GB transfer take?
At 100 Mbps, roughly 30 to 35 minutes. At 200 Mbps, about 15 minutes. Your actual speed depends on the network, but FileSendZone transfers at your full internet speed since there is no server bottleneck.
Is a 20 GB file transfer safe on FileSendZone?
Yes. Your 20 GB file goes directly from your device to the recipient using peer-to-peer technology. It is never stored on any server. No one can intercept or access your file during the transfer.
Can both devices be in different countries?
Yes. FileSendZone works across the internet. The sender and receiver do not need to be nearby or on the same network. Any two devices with an internet connection and a browser can use it.
What happens if the connection drops during a 20 GB transfer?
If the connection drops, the transfer will stop. You will need to restart it. For very large transfers on unstable connections, a wired internet connection on both sides is recommended for better reliability.
