What's My Browser? — Browser & Device Info
See exactly what your browser exposes about you — user agent, operating system, screen and viewport, timezone, languages, CPU cores and more. Every value is read locally in your browser and nothing is ever sent anywhere.
About this browser info tool
Your browser knows a surprising amount about the device it runs on, and it exposes much of it to JavaScript so that pages can adapt. This tool simply reads those built-in values — from the navigator, window, screen and Intl objects — and lays them out in one place so you can see what any website could read the instant you visit.
None of the fields here require a network request. The user agent, platform, preferred languages, screen and viewport dimensions, device pixel ratio, colour depth, timezone, cookie and Do-Not-Track settings, online status, logical CPU cores and (where supported) approximate device memory are all local properties of your browser. That is why the page fills in even with your connection turned off.
Everything you see was gathered by JavaScript on this page and shown only to you. No user agent, timezone or screen size is uploaded, logged or stored by IP Animals. The Copy-all button puts the report on your clipboard for you to share deliberately, if you choose.
Why this matters for privacy
Individually these values seem harmless, but combined they form a remarkably unique signature. Sites can stitch your user agent, screen size, timezone, language list and hardware hints together into a browser fingerprint that follows you even when you clear cookies or use private mode. Notice that your public IP address is not shown here — it isn't part of the local browser environment — which ties into the wider question of whether an IP address is personal data.

Frequently asked questions
Is any of this information sent to a server?
No. Every value on this page is read from your browser's own navigator, window, screen and Intl objects using JavaScript, and displayed only to you. Nothing is uploaded, logged or stored. You can go offline and the page still fills in.
Does this show my IP address?
No. Your IP address is not part of the browser's local JavaScript environment — it is only visible to servers you connect to. This tool shows only what your browser exposes locally. To see your public IP, use the What Is My IP tool.
Why does my screen size look wrong?
Screen width and height are reported in CSS pixels, then multiplied by the device pixel ratio to get physical pixels. A phone may report 390×844 CSS pixels at a ratio of 3, which is a 1170×2532 physical panel. Both numbers are shown so you can compare.
Can websites really see all this?
Most of it, yes. Any site you visit can read these same values in JavaScript, and combined they form a browser fingerprint that can identify you even without cookies. Our fingerprinting guide explains how it works and how to reduce it.
