Browser information

What every website can see about you

None of the values above required a permission prompt. They are read from standard web APIs that exist so pages can adapt to your device — and the same APIs let any site build a profile of your setup the moment you load it.

Screen and viewport

Screen resolution is the size of your display; viewport is the visible area inside the browser window, which is smaller and changes when you resize or open developer tools. Device pixel ratio tells a site how many physical pixels back each CSS pixel — 2 or 3 on modern phones and Retina displays — so it can serve appropriately sized images.

Timezone and language

Your timezone is derived from your operating system clock, not your IP address, which is why it can disagree with your apparent location when a VPN is active. That mismatch is a well-known signal: a connection routed through Amsterdam whose browser reports Asia/Baghdad is visibly using a VPN.

Hardware hints

CPU core count and touch support exist to help sites tune their behaviour — limiting parallel work on a modest device, or enlarging tap targets on a touchscreen. They are also strong fingerprinting inputs, because the combination is far less common than any single value.

How fingerprinting works in practice

No single value here identifies you. The power comes from combination. Your browser and version might be shared with millions; add an unusual screen size, a specific timezone, a particular language list and a CPU core count, and the population sharing all of them at once can drop to a handful.

Because it needs no storage, fingerprinting survives clearing cookies and works in private browsing. It is the main reason cookie-blocking alone is not sufficient privacy protection.

Reducing your exposure

• Use a browser that actively defends against it. Tor Browser standardises values across all users; Firefox offers resistFingerprinting; Brave randomises certain outputs.
• Do not over-customise. Every unusual setting adds entropy. A stock configuration blends in better than a heavily modified one.
• Understand what a VPN does. It changes your IP address and nothing on this page. Your fingerprint crosses the tunnel unchanged.

What this page reads, and what it deliberately does not

Everything shown here comes from properties your browser exposes to any script on any page you visit. Nothing is sent to IPGet's server, nothing is stored, and the same values were available to every site you opened today. That is the point of showing them: exposure you cannot see is harder to reason about than exposure you can.

Several things a browser could be asked for are deliberately not requested. Precise geolocation requires a permission prompt and is not asked for. Neither are camera, microphone, clipboard or notification access. Canvas and audio fingerprinting — which extract a stable identifier by measuring tiny rendering differences between machines — are techniques this page describes rather than performs.

Why individually harmless values become identifying together

No single value here identifies you. Millions of people share your browser version, and millions share your screen size. The problem is combinatorial: each additional attribute multiplies the number of distinguishable groups, and a handful of ordinary values can narrow a population of billions down to a group small enough to be tracked without a cookie.

Timezone, language list, screen dimensions, pixel ratio, platform, and the set of fonts a system has installed are the classic inputs. This is why the more unusual your configuration, the more identifiable you are — an uncommon font set or an exotic language ordering does more to single you out than a common browser does to hide you. Reducing exposure means looking more like everyone else, not more locked down.

Browser vendors have been narrowing this surface for years: the User-Agent string has been frozen and reduced, and Chromium browsers now send low-entropy hints by default while requiring a server to ask explicitly for anything more specific. Passive fingerprinting is meaningfully harder than it was, though it has not gone away.
