Browser fingerprint checker
See what your browser gives away besides its IP address: canvas, graphics card, fonts, screen, time zone and more, plus a check of whether those signals agree with each other. It runs entirely in your browser and sends nothing anywhere.

Consistency checks
Sites rarely block a browser for one value. They block it when the values contradict each other. These are hints, not verdicts.

Every signal this page can read
Any website can read the same values without asking you.
The tables appear here once the page has read your browser.
Why this matters when you use proxies
A proxy changes one signal. A fingerprint is made of dozens.
The IP is only one signal
A new IP with the same canvas hash, fonts and graphics card is still recognisably the same browser. Check your address with What is my IP, then look at everything else here.
Profiles need their own fingerprint
Anti-detect browsers give each profile its own consistent set of values. Pair each profile with its own IP, as described on the social media proxies page.
The values have to fit the IP
Time zone and language should match the country of the proxy, and nothing should leak around it. Run the WebRTC leak test with the proxy switched on.
Browser fingerprint questions
What is a browser fingerprint?
A set of values a site can read from your browser without cookies: how it draws text and graphics, which fonts and graphics card it has, its screen, time zone and language. Combined, they are distinctive enough to recognise a browser when it returns.
Does a proxy change my fingerprint?
No. A proxy changes your IP address and nothing else. To change the fingerprint you need a separate browser profile, which is what anti-detect browsers provide. Most people use both together.
Is the fingerprint ID on this page the one websites see?
No. There is no single fingerprint. Every tracking script picks its own signals and computes its own ID. The ID here is a hash of the values listed on this page, shown so you can tell whether two browsers or profiles differ.
Why did my ID change?
Because one of the values changed: a browser update, a new font, a different screen or graphics driver. Window size is left out of the ID on purpose, so resizing the window does not change it.
What do the warnings mean?
That two values contradict each other, or that a value is typical of automated browsers. They are hints. A warning does not mean you will be blocked, and a clean result does not mean you cannot be recognised.
Do you store my fingerprint?
No. Everything is read and hashed inside your browser. This page makes no network request with the results and stores nothing. The “Copy report” button copies the values to your own clipboard.
