OnionShare

Without a doubt, nowadays, you can easily share files thanks to an impressive number of available online file sharing services. However, if you want to be absolutely sure that your privacy stays untouched, then the options you are left with are by no means many.
As you may have guessed based on reading its name, OnionShare is an efficient and user-friendly application that relies on Tor, the most popular 'anonymity network' out there,  in order to share data in a secure and untraceable manner.

Easy installation and minimal configuration process

Before you can get started with this interesting application, you need to make sure that Tor Browser is up and running on your computer's system. Once this is taken care of, you can proceed with the app's installation that should be done in under a minute.
Once installed, you can launch the app via its default executable file and start using it right away, since it does not require complicated configuration. This said, upon launching the app for the first time, you will be greeted by a simple and intuitive user interface.

Share files while taking advantage of everything that Tor Onion has to offer

Thanks to its dedicated buttons, you can swiftly add files or entire folders or even easier, you can drag and drop files directly onto the app's main window. Once you start the sharing process, the application starts the Tor Onion server, loads the data and generates a random and very hard to guess URL link for the available package.
Considering this app is all about ensuring secure sharing of your files, it should come as no surprise that only users with Tor Browsers will be able to access the shared package. Furthermore, you should also know that if the "Stop sharing automatically" box is checked, the server will be shut down once a download has been completed.

Simple, secure and efficient way to share files

Taking everything into consideration, OnionShare is an effective and novice-accessible file sharing application that allows all category of users to share content securely without compromising their privacy and without having to deal with third-party servers.
