Fingerprint Intelligence
Browser Fingerprint Checker
Get a shareable report that outlines how unique your digital fingerprint is. We run everything in your browser so your data never leaves your device.
The Browser Fingerprint Checker gathers a snapshot of client-side signals such as user agent, timezone, screen size, language, rendering hints, and other browser capabilities. It summarizes those signals into a hashed identifier so you can see how unique your setup appears to websites.
Your fingerprint summary
We combine dozens of browser signals (network, device, locale, rendering) to generate a hashed ID.
Collecting data... What this tool does
The Browser Fingerprint Checker gathers a snapshot of client-side signals such as user agent, timezone, screen size, language, rendering hints, and other browser capabilities. It summarizes those signals into a hashed identifier so you can see how unique your setup appears to websites. All calculations run locally, so the data stays in your browser while you get a clear view of your current fingerprint profile.
When to use this tool
Use it when you want to understand how trackable your browser is or when testing privacy changes like a new extension, profile, or VPN. It is also useful alongside security checks such as SSL Certificate Viewer when you are evaluating how a site handles visitor security and identity signals.
How it works
The tool reads available browser APIs to collect a set of non-sensitive signals, normalizes them, and combines them into a single hash. It then displays the raw values so you can understand which factors contribute most to uniqueness. Refreshing the page re-runs the process, allowing you to compare changes over time.
Example use case
You install a new privacy extension and want to confirm it reduces fingerprint uniqueness. Load the tool, record the hash and key values, enable the extension, and refresh. If the hash changes and fewer signals are reported, you can confirm the extension is altering trackable attributes.
Use cases
- Assess how a new privacy extension changes your fingerprint.
- Compare browser fingerprints before and after enabling a VPN.
- Document client environment details for support cases.
Notes & limitations
A fingerprint is a snapshot, not a guarantee of anonymity. Some sites combine fingerprints with server logs, cookies, or login data. The signals displayed here may differ across browsers and updates, and some privacy features deliberately randomize values. Use the results as guidance and pair them with broader privacy practices.
A stable fingerprint can still appear different when you switch networks or use a private browsing session. Treat the hash as a comparison tool rather than a permanent identifier. If you want to reduce uniqueness, focus on consistent, minimal browser configuration across sessions.
