How to send a 50 GB file online
By the WispFile team · Updated 24 September 2026
To send a 50 GB file online you need either a paid cloud plan with at least 50 GB of room, or a direct transfer that skips storage entirely. Free upload services stop far below 50 GB. A direct transfer (browser to browser) has no storage limit and no upload-then-download wait, but both computers must stay online, and at typical home upload speeds 50 GB takes hours either way.
Key facts
- 50 GB is over every free cloud tier compared here.
- At 20 Mbit/s upload it takes about 5.6 hours; at 100 Mbit/s, about 67 minutes.
- A direct transfer saves the second leg: the receiver downloads while you send.
- Keep both machines awake and on power for the whole transfer.
Your options for 50 GB
| Option | Works for 50 GB? | What it costs you |
|---|---|---|
| No | Attachments stop at 20–25 MB | |
| WeTransfer Free | No | 3 GB in total per 30 days |
| Dropbox Basic, OneDrive free, Google Drive free | No | 2 GB, 5 GB and 15 GB of storage |
| Paid cloud storage | Yes | A plan with the space; upload, then their download |
| USB drive or SSD by courier | Yes | A day or more in the post; a drive to lose |
| Direct browser transfer (WispFile) | Yes, no limit set | Both computers online until it finishes |

How long 50 GB really takes
The bottleneck is almost always the sender’s upload speed. Fibre and office lines upload fast; cable and DSL broadband often upload at a tenth of their download speed. Run a speed test and read the upload figure.
| Upload speed | Direct transfer | Upload service (upload + download) |
|---|---|---|
| 10 Mbit/s | 11 hours | About 22 hours |
| 20 Mbit/s | 5.6 hours | About 11 hours |
| 50 Mbit/s | 2.2 hours | About 4.5 hours |
| 100 Mbit/s | 67 minutes | About 2.2 hours |
| 500 Mbit/s | 13 minutes | About 27 minutes |
The right-hand column assumes the receiver downloads at the same speed as you upload; a faster download shortens the second leg but never removes it.
How to send 50 GB directly
- Test first. Send a small file to the same person. If it connects, the big one will too. Free links need a direct path between the two networks.
- Prepare the machines. Plug both in, turn off sleep, and check the receiver has 50 GB free plus some headroom.
- Use Chrome or Edge on the receiving end if you can: they write the file straight into the chosen folder.
- Send. Add the file on WispFile, share the link, and leave the tab open.
- If it drops, carry on. A dropped connection pauses the download; when both sides are back it continues from the last verified piece, not from zero.
What is verified, and what is not yet
We publish what we have measured. 5 GB transfers are verified end to end: the copy arrived with an identical SHA-256 and the receiver used under 10 MB of memory, because the file streams to disk in 256 KB pieces. Nothing in that design changes at 50 GB, and 50 GB is the next test on our list. Until it is published, treat very large transfers as untested and keep the test-file habit.
Tips for very large transfers
- Send over a wired connection or strong Wi-Fi; weak Wi-Fi halves throughput.
- Pause cloud backups and big downloads on the sending machine.
- For video, send an edit or proxies first so the other person can start, then the camera originals. See sending large video files.
- Same building? Put both machines on the same network: direct transfers between them run at local network speed.
Frequently asked questions
How long does it take to send 50 GB?
At 20 Mbit/s of upload, about 5.6 hours; at 100 Mbit/s, about 67 minutes; at 500 Mbit/s, about 13 minutes. With an upload service the receiver also waits for their download afterwards, so their total wait is roughly double.
Can I send 50 GB for free?
Not through the free tiers of the common upload services: WeTransfer Free allows 3 GB in 30 days, Dropbox Basic 2 GB, OneDrive 5 GB of storage and Google Drive 15 GB shared with Gmail. A direct transfer has no storage to fill, so it costs nothing, but both computers must be online for the whole transfer.
Does WispFile handle 50 GB?
No limit is set and files stream to disk rather than memory, so the size is handled the same way as a small file. So far, transfers are verified end to end up to 5 GB; 50 GB is being tested now. Send a small test file first to check the two networks connect directly.
Should I compress a 50 GB file first?
Only if it compresses. Video, photos and existing archives barely shrink, so zipping them wastes time. Raw data, layered design files, CAD and databases often shrink a lot and are worth compressing.
