OnionShare lets you securely and anonymously share files of any size. It works by starting a web server, making it accessible as a Tor onion service, and generating an unguessable URL to access and download the files. It doesn’t require setting up a server on the internet somewhere or using a third party file-sharing service. You host the file on your own computer and use a Tor onion service to make it temporarily accessible over the internet. The other user just needs to use Tor Browser to download the file from you.

- Invisible to users, but this version includes some major refactoring of the codebase, and a robust set of unit tests which makes OnionShare easier to maintain going forward
How to Use
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.
