Think You’re Anonymous Online? Think Again.
You’ve cleared your cookies.
You’re using Incognito Mode.
You’ve even connected to a VPN.
But websites still know who you are.
How?
Through something called a browser fingerprint — and chances are, you’re leaking far more than you think.
In this guide, you’ll learn:
- What browser fingerprinting is
- How websites track you invisibly
- How to check your fingerprint without using any extensions
- How to reduce and protect your digital fingerprint in 2025
Let’s pull the curtain back on one of the internet’s most silent tracking methods.
What Is Browser Fingerprinting?
Browser fingerprinting is a method websites use to uniquely identify you based on your browser’s configuration and device details — even if you don’t log in or accept cookies.
It collects:
| Detail Collected | Example |
|---|---|
| Browser type & version | Chrome 125, Firefox 118 |
| OS & Device | Windows 11, macOS, Android |
| Screen size & resolution | 1920×1080 |
| Installed fonts & plugins | Arial, WebGL, Java |
| Language & time zone | en-US, GMT+5 |
| Hardware info | CPU, GPU, Battery status |
| Canvas/WebGL fingerprint | Unique drawing behavior |
| Audio & media decoding | How your browser plays sound |
| Network data | IP address, proxy, Tor, VPN usage |
All this forms a unique fingerprint, often more accurate than cookies.
Why Is It a Privacy Threat?
Even with VPNs and Incognito Mode, browser fingerprinting can:
- Track you across websites
- Link different sessions together
- Bypass cookie blockers and anti-tracking tools
- Expose VPN usage or Tor connections
How to Check Your Browser Fingerprint
Here are 3 completely free, no-install websites to analyze your fingerprint instantly:
1. AmIUnique.org
✅ Free open-source tool
✅ Shows uniqueness score
✅ Compares you to global user base
✅ No extension required
How to use:
- Visit https://amiunique.org
- Click “View My Fingerprint”
- Review the details (canvas hash, screen info, timezone, etc.)
2. Device Info – CreepJS
✅ Most detailed fingerprint analysis tool (2025)
✅ Shows canvas, WebGL, font detection, emoji support
✅ Highlights what makes your fingerprint unique
How to use:
- Open: https://abrahamjuliot.github.io/creepjs/
- Scroll down to see all your browser leaks
- Hover over “Lies” to see if your browser is trying to spoof data (and failing)
3. Cover Your Tracks (EFF)
✅ Run by Electronic Frontier Foundation
✅ Tests tracking protection, ad blocking, fingerprinting protection
✅ No signup, no extension needed
How to use:
- Visit: https://coveryourtracks.eff.org/
- Click “Test your browser”
- Read the results for:
- Trackers blocked
- Unique fingerprint
- Protection score
How to Reduce Browser Fingerprinting (Working Fixes – 2025)
Even though you can’t fully erase your fingerprint, you can confuse it enough to become “noisy” — making tracking unreliable.
1. Use Firefox with Enhanced Tracking Protection
✅ Firefox has built-in fingerprint blocking
Go to:
- Settings > Privacy & Security
- Set to “Strict”
2. Use Brave Browser (Best in 2025)
Brave randomizes fingerprinting data and blocks tracking scripts out of the box.
Benefits:
- Anti-fingerprinting
- Script blocking
- Built-in VPN (Brave Premium)
- Shields reports to show blocked attempts
3. Turn Off JavaScript (When Possible)
Most fingerprinting happens through JS.
Use extensions like NoScript, or in Brave/Firefox, toggle JS for sensitive sites.
⚠️ Downsides:
- Some sites may not load properly
- Breaks dynamic pages (e.g. Google Docs)
4. Disable or Control Canvas & WebGL
Use Firefox privacy flags or extensions to spoof or block canvas fingerprinting.
Example in Firefox:
- Go to:
about:config - Search:
privacy.resistFingerprinting→ Set totrue
5. Use Tor Browser (For High-Privacy Use)
Tor browser is designed to make every user look the same — defeating fingerprinting.
⚠️ Not ideal for daily browsing (slow, may trigger captchas), but great for:
- Whistleblowing
- Activism
- Private research
6. Avoid Logging In While Using Anti-Fingerprint Methods
If you check Gmail, Facebook, etc., while trying to hide your fingerprint — you just linked it to your real identity.
Always separate anonymous and real sessions.
Real User Experience
“I was browsing a forum about VPN leaks. I had VPN, Incognito, and cleared cookies.
But then I visited CreepJS… and boom — it showed 99.7% unique fingerprint.
That’s when I realized: even with VPN, I was being tracked.”Now I browse with Brave, use Firefox containers, and feel truly invisible.

FAQs – Browser Fingerprinting & Privacy (2025)
🔹 What is a browser fingerprint?
A unique set of data collected from your browser (like screen size, fonts, plugins) that can be used to identify and track you online.
🔹 Can websites track me even with a VPN?
Yes. If your browser fingerprint is unique, websites can still recognize you across sessions and VPNs.
🔹 What’s the best browser to avoid fingerprinting?
- Best (daily use): Brave
- Best (maximum privacy): Tor
- Best mainstream: Firefox (with privacy settings enabled)
🔹 Can I remove my browser fingerprint?
Not completely. But you can blend in by using tools that make your fingerprint similar to others.
🔹 Is Incognito Mode enough?
No. Incognito only clears cookies and history — it does not protect against fingerprinting or DNS leaks.
Final Thoughts: Privacy Isn’t Just About VPNs
You may think you’re invisible — but your browser fingerprint is loud and unique.
Now you know how to:
- Check it without any tools
- Understand what makes it unique
- Reduce it and protect yourself
💡 Privacy in 2025 is not automatic — it’s intentional.
