Before you can share files, you need to open Tor Browser in the background (or install and run a system Tor service). This will provide the Tor service that OnionShare uses to start the onion service.

Open OnionShare and drag and drop files and folders you wish to share, and click Start Sharing. It will show you a .onion URL such as http://asxmi4q6i7pajg2b.onion/egg-cain and copy it to your clipboard. This is the secret URL that can be used to download the file you’re sharing. If you’d like multiple people to be able to download this file, uncheck the “close automatically” checkbox.

Send this URL to the person you’re trying to send the files to. If the files you’re sending aren’t secret, you can use normal means of sending the URL: emailing it, posting it to Facebook or Twitter, etc. If you’re trying to send secret files then it’s important to send this URL securely.

The person who is receiving the files doesn’t need OnionShare. All they need is to open the URL you send them in Tor Browser to be able to download the file.

You can download OnionShare for Windows and macOS from https://onionshare.org/. It should be available in your package manager for Linux, and it’s included by default in Tails.
