Send Large Files Free

Too big for email? Send videos and files up to 10 GB each, straight to the other device. Nothing is uploaded, so there is no waiting for an upload and no link that expires.

🔒 Files never stored
What “files never stored” means for this tool

Files go straight between your two devices over an encrypted link that only those two devices can read. They are never uploaded to this website or stored anywhere.

How the devices find each other: for a few seconds, a small pairing service (pair.kcnebula.com) passes connection details between them, such as their internet addresses. It never sees the files, their names or their sizes, keeps nothing on disk, and forgets each pairing within 10 minutes.

Different networks are fine (say your phone on mobile data and your computer on home Wi-Fi): each device finds its own public internet address and they connect straight across the internet. A few networks, such as some office, school and mobile networks, block direct links. If yours does, the page tells you, and putting both devices on the same Wi-Fi fixes it. Files are never sent through a server instead.

On the receiving device, large files are written to the browser's own private storage as they arrive, then removed after you save them.

Who can see what: the two devices learn each other's internet address, as with any direct connection. Like any website, the server that delivers this page sees basic connection details such as your IP address. This site counts visits with privacy-friendly analytics: no cookies, no ads, never anything you send.

On your other device, scan this code

or open kcnebula.com/transfer and type

····-····

Send the link to your other device (text, email, chat) and open it there to link up.

Got a code from another device?

Type the 8-character code it shows.

How it works

  1. Open this page on both devices. Any phone, tablet or computer with a modern browser. No app, no account.
  2. Pair them. Scan the code with the other device's camera, or type the 8-character code into it. Each code works once and expires after 10 minutes.
  3. Check the symbols. Both screens show the same four symbols when the link is private to your two devices. If they differ, press Disconnect.
  4. Send. Drop files in on either device, in either direction, as many as you like, up to 10 GB each. On the other device, press Save (or Share… on phones).

How often does linking fail, and why?

Most pairs of devices link directly. In studies of real-world connections, roughly 8 to 15 in every 100 pairs of networks can't, because of how the network is set up rather than anything wrong with your devices:

The fix: put both devices on the same Wi-Fi, or turn on your phone's hotspot and join it from the computer. Direct links between devices on the same network almost always work. Files are never sent through a server as a fallback.

How to use the Send Large Files Free

  1. Open this page and send the other person the code (or the link it makes).
  2. They open kcnebula.com/transfer and type the code.
  3. Both check the symbols match.
  4. Drop the files in. They save them on their side.

Questions

How big can the files be?

Up to 10 GB per file, as many files as you like.

Do both people need to be online at the same time?

Yes. Files go directly between the two devices, so both keep the page open until the transfer finishes. Nothing waits on a server.

Are my files uploaded anywhere?

No. They go straight from one device to the other over an encrypted link and are never stored on a server.

Is it encrypted?

Yes, always. Files travel over an encrypted link between the two devices, and both screens show matching symbols so you know nobody is in the middle.
