Does a VPN slow your internet down?

Yes. Anyone who tells you otherwise is selling something. The useful question is how much, and whether you will notice.

What you should expect

On a decent connection to a nearby server, somewhere between 5% and 15%. On a 100 Mb line that is the difference between 100 and about 88, which no human notices while streaming, browsing or on a call.

Connecting to a server on another continent is different. Physics does not negotiate: London to Sydney is roughly 17,000 km each way, and light takes time. Expect a real drop and noticeably higher latency.

What actually causes it

Distance. The dominant factor by a wide margin. A server in London behaves very differently from one in Singapore.

Encryption. Real but small on any device made in the last decade. WireGuard, which we use, is substantially lighter than the older OpenVPN.

Server load. A crowded server is slow regardless of how close it is. This is the usual culprit when a free VPN crawls.

Your own connection. A VPN cannot make your line faster than it is, and on poor Wi-Fi the VPN is rarely the bottleneck.

When a VPN is genuinely faster

Rare, but real:

Your provider is throttling something. Some providers slow particular traffic types. They cannot identify what they cannot see, so a VPN can restore full speed.

Bad routing. Occasionally your provider's path to a service is congested and the VPN's is not.

Making it faster

• Pick a nearby server. The single biggest lever. If you do not need a specific country, choose

the closest one.

• Use WireGuard rather than an older protocol, if your app offers the choice.
• Try a different server in the same country. Load varies.
• Use a wire if you are chasing the last few percent. Wi-Fi is usually the real limit.

What actually matters for how it feels

For streaming, browsing and calls, latency matters more than raw speed. A nearby server with a 15 ms round trip feels instant even if your headline number dropped. A distant one at 300 ms feels sluggish even at high throughput.

Which is the practical advice: choose close unless you have a reason not to.
