Check the browser, screen, language, timezone, canvas, and WebGL signals websites can read from your device.
This browser fingerprint check shows the signals websites can read from your device without asking for a login. It inspects your browser, screen, language, timezone, hardware hints, canvas rendering, and WebGL details, then creates a local fingerprint hash. Everything runs in your browser and the report is not sent to a server.
Open the page and the fingerprint report is generated automatically. Use Refresh scan to run it again after changing browser settings, or Copy report to copy the visible signals and local hash. Use the results to understand what a website can see, not as a guarantee of anonymity.
People often think tracking starts when they sign in or accept cookies. In reality, a browser exposes a collection of technical signals before any of that happens. Screen dimensions, timezone, rendering behaviour, graphics details, language settings, and platform hints can combine into a setup that is more distinctive than it first appears.
This tool is useful because it turns that abstract idea into something inspectable. Instead of talking about fingerprinting in general terms, you can see the kind of browser-side signals a site can read from your current session.
If you want to understand how identifiable your browser looks before you log in anywhere, this gives you a practical snapshot.
Different browsers, devices, and profiles often expose noticeably different combinations of signals. Seeing those differences side by side is more informative than assuming they behave the same.
If you change an extension, hardened setting, or browser mode, this tool helps answer the useful question: what actually changed?
Timezone or language on its own may not feel revealing. The issue is the combined pattern, not any single field in isolation.
The local hash is useful as a quick comparison aid between runs. It is not a universal truth about how every tracker or anti-fraud system identifies you.
Changing one exposed value may make a difference, but fingerprinting is about collections of attributes, not one switch.
It is common to install privacy tooling and assume the browser now looks generic. A before-and-after scan is more reliable than assumption.
If one browser instance is treated differently from another, exposed client-side signals are one place to start comparing.
Fingerprinting sounds vague until the relevant attributes are visible together in one report.
This tool inspects common browser-side fingerprint signals. It does not prove whether a specific site is tracking you, measure every possible detection technique, or guarantee anonymity. It is an inspection tool, not a privacy promise.
Privacy decisions improve when they are grounded in something observable. Seeing what your browser exposes is more useful than treating fingerprinting as a purely theoretical concern.
A browser fingerprint is a combination of details your browser exposes, such as screen size, timezone, language, browser features, and graphics rendering. The combination can help websites recognise a browser even without cookies.
No. The scan runs locally in your browser and does not send the fingerprint report or hash to smpl.tools.
No. It can change when you update your browser, change settings, switch devices, add extensions, or use privacy protections.
Graphics rendering can vary by hardware, driver, browser, and operating system. Those differences can become part of a fingerprint.
This tool runs entirely in your browser. Nothing you type or paste is sent to any server — all processing happens locally on your device.
