What is the largest file you can send online?
With a file transfer service the practical ceiling is set by the plan rather than by the technology. On MyAirBridge that means 20 GB on the free tier, 50 GB on Basic, 250 GB on Pro, and no limit at all on Enterprise.
Limits by plan
| Plan | Per-transfer limit | Storage |
|---|---|---|
| Guest and Free | 20 GB | None |
| Basic | 50 GB | 200 GB |
| Pro | 250 GB | 2 TB |
| Enterprise | Unlimited | Unlimited, geo-redundant |
What limits you in practice
- upload speed, which decides how long the transfer takes rather than whether it is possible
- connection stability over hours-long uploads
- the recipient's ability to download and store the result
- available disk space on both ends
At 100 Mbps upload, 250 GB takes roughly six hours under ideal conditions, so scheduling matters as much as the limit itself.
How other methods compare
| Method | Practical ceiling |
|---|---|
| Email attachment | About 25 MB |
| Free transfer services | Usually 2 to 20 GB |
| Cloud storage free tiers | 5 to 15 GB total, not per transfer |
| Paid transfer plans | Hundreds of gigabytes or unlimited |
| Physical drive by courier | Any size, but slow and manual |
For very large deliveries
Above a few hundred gigabytes, the question shifts from limits to logistics: start the upload when the connection is otherwise idle, use a wired connection, and keep the material in storage rather than repeating the transfer for each recipient.
FAQ
What is the biggest file I can send online?
On MyAirBridge, 20 GB free, 50 GB on Basic, 250 GB on Pro, and unlimited on Enterprise.
Is there a technical maximum?
In practice the limits are commercial rather than technical. Time and connection stability become the real constraints for very large transfers.
How long does a very large upload take?
At 100 Mbps upload speed, roughly half an hour for 20 GB and around six hours for 250 GB, before overhead.
Summary
Transfer size limits are set by plan: 20 GB free, up to unlimited on Enterprise. Beyond a certain size the constraint stops being the limit and becomes upload time, connection stability, and what the recipient can handle.
