Browser Fingerprint Test
Your browser silently reveals dozens of data points that websites can combine into a unique identifier - Without setting a single cookie. This test shows exactly what is exposed and how unique your fingerprint likely is. No data is stored or transmitted.

What Is Browser Fingerprinting?
Browser fingerprinting is a tracking technique that collects technical attributes from your browser and device - Canvas rendering, installed fonts, screen resolution, WebGL renderer, timezone, language, CPU core count, and more. Individually each attribute is unremarkable, but combined they form a profile that is statistically unique for the majority of users. For a full explanation of the technique, read our guide on what browser fingerprinting is.
Unlike cookies, fingerprints:
- Cannot be deleted - Clearing cookies does not change your canvas hash or WebGL renderer
- Persist across private/incognito windows - Your hardware does not change
- Work across different browsers on the same device if hardware attributes are shared
- Do not require any storage permission on your device
How Fingerprinting Is Used
Fingerprinting is only one part of the picture - Our FAQ covers what data your browser leaks.
| Use Case | Who Uses It | Impact on You |
|---|---|---|
| Cross-site tracking | Advertising networks (Google, Meta, trade desk) | Your activity is linked across every site that loads their script |
| Fraud detection | Banks, payment processors, e-commerce | Legitimate use - Detects account takeovers and carding fraud |
| Bot detection | Cloudflare, Akamai, reCAPTCHA | Distinguishes real users from automated scripts |
| Re-identification after VPN | Advertisers, state actors | Even with a different IP, the fingerprint links sessions back to you |
| Paywalls and geo-blocks | News sites, streaming services | Enforces article limits even after clearing cookies |
How to Reduce Your Fingerprint
| Browser / Method | Canvas Protection | WebGL Protection | Font Enumeration | JS API Noise | Verdict |
|---|---|---|---|---|---|
| Regular Chrome / Edge | None | None | Exposed | None | Fully fingerprintable |
| Firefox (default) | Partial | Partial | Limited | None | Better than Chromium, not sufficient |
| Firefox + privacy.resistFingerprinting | ✓ Randomised | ✓ Spoofed | ✓ Blocked | ✓ Normalised | Strong - May break some sites |
| Brave Browser | ✓ Randomised | ✓ Randomised | ✓ Blocked | ✓ Noised | Strong - Good everyday usability |
| Tor Browser | ✓ Uniform | ✓ Uniform | ✓ Uniform | ✓ Uniform | Best - All users appear identical; very slow |
Practical Steps to Protect Yourself
- Switch to Brave or Firefox: Both offer built-in fingerprint randomisation. Firefox's
privacy.resistFingerprintingflag (about:config) is the strongest option while maintaining good usability. - Use a VPN: Hides your IP so your fingerprint cannot be trivially linked to a specific ISP subscriber. Our Best VPNs guide covers audited, no-logs options. Test it with our VPN Leak Test.
- Disable WebGL or use a spoofer: WebGL renderer and vendor are highly unique - Brave randomises these per session.
- Block JavaScript trackers: uBlock Origin in medium mode blocks most fingerprinting scripts before they run.
- Standardise your window size: A maximised browser window at an unusual resolution is distinctive. Tor Browser uses a fixed 1000×800 window for all users.
- Use Tor Browser for sensitive sessions: The strongest protection - All users appear identical. Pair it with our Proxy Check to verify Tor is routing correctly.
Frequently Asked Questions
Can a website fingerprint my browser without cookies?
Yes. Fingerprinting needs no cookies or storage at all - It combines attributes your browser freely reports, such as canvas and WebGL rendering output, installed fonts, screen resolution, timezone, language, and hardware details. Together these are often unique among millions of visitors, which lets sites recognise a returning browser even after you clear cookies.
Does incognito or private mode stop browser fingerprinting?
No. Private browsing deletes cookies and history when the session ends, but it does not change your hardware, fonts, screen size, GPU, or timezone, so your fingerprint stays essentially identical. The same device produces the same fingerprint in normal and private windows, which is exactly why trackers use the technique alongside or instead of cookies.
How can I reduce my browser fingerprint?
Aim to blend in rather than stand out. Tor Browser makes all its users look alike by design, Firefox offers a resistFingerprinting setting, and Brave randomises canvas and WebGL output. Avoid unusual fonts and niche extensions, and keep your window at a common size. Paradoxically, stacking many anti-tracking add-ons can make your browser rarer and easier to recognise.
