The reality is that all VPNs will slow down your internet connection to some extent. This is because they have to encrypt and decrypt your data, and route it through a server somewhere else in the world. All of that takes time, so it makes sense that VPN connections are slower than regular ones. However, the best providers keep this speed loss to a minimum. With the fastest VPNs, you probably won’t even notice any difference from your regular connection. That means you won’t have to deal with buffering, lag, or long loading times while connected to the VPN.
