How to Send Large Files (10 GB+) for Free — Without WeTransfer or Email
Email caps at 25 MB. WeTransfer free at 2 GB. The fastest, simplest way to send anything bigger is peer-to-peer — and the math on why is striking.
The math, in one widget
Drag the slider below to set a file size. The bars race in real time to show how long the same file takes by each common method — and which ones refuse outright.
Why P2P pulls ahead at every size
Cloud upload-and-download is doing the work twice: the file has to travel from you to the server (your upload speed, often slow) and then from the server to the recipient (their download speed). P2P skips the middle entirely and uses the fastest path between the two devices — which, on the same Wi-Fi, is your router itself.
The real “limits” of free services
- Gmail / Outlook attachments — 25 MB hard cap. Anything bigger gets rewritten into a Drive/OneDrive link.
- WeTransfer free — 2 GB per transfer. After that you need WeTransfer Pro at €10/mo.
- Google Drive free — 15 GB total quota across Gmail and Photos. One 4K wedding video can eat half of it.
- iCloud Mail Drop — 5 GB per file, 30-day expiry, requires an Apple ID on both sides.
- InterDrop P2P — no cap. Throughput is whatever your network supports.
Free tiers exist to upsell you to paid tiers. P2P doesn’t have tiers — it just runs.
When to use what
- Up to 25 MB, recipient checks email anyway → email attachment.
- Few hundred MB, recipient is offline → Drive/Dropbox link.
- Anything 1 GB+, both sides can open a browser → P2P, always.
- Sensitive file of any size → P2P, no server copy to worry about.
