Browser Fingerprint
See what websites can quietly detect about your browser and device — the signals that make up your browser fingerprint, plus the combined hash that can identify you across sites.
About this tool
A browser fingerprint is a profile a website builds from dozens of small details your browser exposes — screen size, time zone, language, fonts, graphics hardware, and the subtle way your device renders a hidden image (canvas and WebGL). Combined, these signals are often unique enough to identify and track you without cookies. This test shows you exactly what is exposed and combines it into a single fingerprint hash.
What is being collected
Everything on this page is read using ordinary browser APIs that any website can call — no permissions required. That is the point: you are not granting access, the data is simply available. The more unusual your combination of signals, the more identifiable you are.
Runs entirely in your browser
Your fingerprint is computed locally and never sent anywhere. This tool exists to show you what trackers see, not to track you.
How to reduce your fingerprint
- Use a mainstream browser with default settings — being common makes you blend in.
- Consider anti-fingerprinting browsers like Tor Browser, or antidetect browsers that deliberately spoof these signals for managing multiple accounts.
- Combine with a proxy or VPN — fingerprinting and IP address are separate signals; changing one alone is not enough.
Frequently asked questions
It is a unique profile built from details your browser exposes — screen size, time zone, fonts, graphics hardware, canvas rendering and more. Together these can identify and track you across websites without using cookies.
It is widely used for analytics and fraud prevention and is generally legal, though privacy laws like GDPR may require disclosure and consent when it is used to track individuals. Either way, most sites do not make it visible to you.
Use a privacy-focused browser such as Tor, use an antidetect browser that spoofs these signals, or stick to default settings in a common browser so you blend in. Pair it with a proxy or VPN, since your IP is a separate signal.
No. Every signal is read and hashed entirely in your browser and nothing is transmitted or saved. The tool only shows you what websites are able to see.
