The safest and simplest way to download Tor Browser is from the official Tor Project website at https://www.torproject.org. Your connection to the site will be secured using HTTPS, which makes it much harder for somebody to tamper with.
However, there may be times when you cannot access the Tor Project website: for example, it could be blocked on your network. If this happens, you can use one of the alternative download methods listed below.
