Internet diagnostic tool

VPN speed test

A VPN can add latency, reduce speed, and expose unstable connections. This test checks whether your connection has enough speed and stability for remote work, private browsing, and VPN-heavy apps.

Ready to test

Test if your internet is actually good enough

Run a quick browser-based diagnostic for calls, gaming, streaming, VPN, and remote work. Verdicts appear before raw technical numbers.

MVP note: latency, jitter, packet loss, and speed are browser-based estimates. Fetch failures/timeouts approximate packet loss and may be affected by blockers, CORS, or third-party test endpoints.

VPN speed test: what the results mean

A VPN can add latency, reduce speed, and expose unstable connections. This test checks whether your connection has enough speed and stability for remote work, private browsing, and VPN-heavy apps.

What matters for VPN quality

  • Download speed for browsing and file downloads.
  • Upload speed for remote desktop, calls, and file sharing.
  • Latency for responsiveness.
  • Packet loss and jitter for stable VPN tunnels.

How to improve VPN performance

  • Choose a closer VPN server.
  • Avoid VPN for real-time apps if latency rises.
  • Use Ethernet before blaming the VPN.
  • Compare results with VPN on and off.

Frequently asked questions

Why is my VPN slow?

VPNs can be slow because of distant servers, encryption overhead, overloaded VPN nodes, ISP routing, high latency, or packet loss.

What speed is good for VPN use?

For everyday VPN use, aim for at least 20 Mbps download, 5 Mbps upload, stable latency, and packet loss below 1%.

Should I use a VPN for gaming or calls?

Only if needed. A VPN often increases latency and jitter, which can hurt games and video calls.
