Send files

Recipients get an expiring link by email and need no account. Every file is hashed in your browser and checked again on arrival.

Choose your files

Drop files here or click to choose them Nothing leaves your browser until you press Send. Each file is then hashed locally, uploaded in verified pieces and checked again on our server.

Who is it for?

The link is emailed to this address and is never shown here, so nobody looking over your shoulder can take it.

Confirm it is you

Only verified accounts can send. Sign in here: your files stay put while you do.

No account yet? Create a free one: it takes about a minute and needs an authenticator app.

Or use your Google or Microsoft account: signing in that way creates your BlckRhino Send account too, if you do not have one yet. It opens in a separate window so the files you have chosen stay where they are.

You can stop and come back once uploading starts. A send begins by checking your files on this device: that part is local, cannot be paused usefully, and starts again if you leave. From the first uploaded part onwards, Pause becomes available and closing the tab is safe: everything already uploaded stays on our servers for seven days. To carry on, open this page again and add the same files: we skip what is already uploaded and send only what is left. If your sign-in has expired by then, we will ask for your authenticator code and continue from the same point.
