About this tool
Track your browser fingerprint
Browser Fingerprint Visualizer shows the signals your browser exposes — things like screen size, fonts, timezone and hardware hints — that sites can combine to identify you. It's an eye-opening way to understand online tracking and your own digital fingerprint.
Open Browser FingerPrint on AltFTool — it loads instantly in your browser.
Add your input to the workspace.
Adjust the options until the result looks right.
Copy or download the output and put it to work.
See the actual signals your browser leaks.
Understand fingerprint-based tracking.
Signals are read and shown in your browser.
No — it reads and displays your own browser's signals locally so you can see them; it doesn't store or transmit them.
It's the combination of browser and device characteristics that, together, can uniquely identify a visitor even without cookies.
Privacy-focused browsers and anti-fingerprinting settings can reduce the signals exposed.
