Free Online Privacy & VPN Tools

We test VPNs for a living. Every review on vpnrank.io starts with the same routine: check the IP the provider hands us, probe the browser for WebRTC leaks, yank the connection to see whether the kill switch holds, and look up the server's real network owner. Over time we turned that internal routine into the public tools on this page, because the questions we answer in our testing lab are exactly the questions readers keep asking us.

Most "free tool" sites exist to harvest emails or push pop-ups. Ours exist so you can verify — not trust — that your privacy setup works. Each tool gives you the raw result first, then explains what it means and what to do if the result is bad. If a result reveals you need a VPN (or a better one), our independently tested VPN rankings are one click away — that's the whole business model, stated plainly.

The first five tools inspect your connection. What Is My IP is the foundation: it shows the public IP address every website, app, and tracker sees, plus the location and internet provider that address reveals. If you run a VPN, this is the fastest way to confirm the IP shown belongs to the VPN server and not to your home connection.

The WebRTC Leak Test covers the sneakiest failure mode: browsers can expose your real IP through WebRTC even while a VPN tunnel is active, silently undoing everything the VPN does. Is My VPN Working? bundles the IP and leak checks into a single pass/fail verdict, and the VPN Kill Switch Test walks you through safely simulating a dropped connection to confirm your VPN blocks traffic instead of leaking it. Finally, IP Address Lookup works in the other direction: paste any IPv4 or IPv6 address — from a server log, a suspicious email header, or your own VPN server — and see its location, network owner, and reverse-DNS hostname.

A VPN hides your traffic, but a weak or leaked password still hands attackers the keys. The Password Generator creates cryptographically random passwords entirely in your browser using the Web Crypto API — no password ever touches our servers. The Password Strength Checker estimates how long real-world cracking hardware would need to break a password and pinpoints what makes it weak, and the Password Leak Checker tests whether a password already appears in known data breaches — using k-anonymity, so the full password never leaves your device.

Three rules apply to every tool here. First, no accounts and no email walls — every tool works the moment the page loads. Second, minimal data: the password tools run entirely client-side, and the IP tools only read the address your browser already presents to every website you visit. Third, no result storage: we don't log lookups, we don't build profiles, and results exist only in your browser tab. The point of a privacy toolbox that spies on you would be hard to explain.

Where a tool needs outside data — like the network owner of an IP address — we say so on the tool page and the request fails gracefully rather than blocking your result.

If you already use a VPN, start with Is My VPN Working? — it catches the most common failures in one run. If you don't use a VPN yet, open What Is My IP and look at how much a single page load reveals: your approximate location, your internet provider, and a stable identifier that follows you across the web. That result is usually the moment the case for a VPN stops being abstract — and our best VPN guide ranks the services that actually fixed it in our tests, led by NordVPN and Surfshark.
