This tool reads the same browser and device signals that any website can access via JavaScript — user agent, screen size, timezone, canvas rendering, WebGL renderer, and more — and combines them into a single SHA-256 hash. Everything runs locally in your browser; nothing is sent to a server.
Here is what your browser reveals to every site you visit — even without cookies or an account.
This tool collects the individual signals your browser exposes through standard JavaScript APIs: user agent, screen resolution, timezone, CPU core count, estimated memory, touch points, and a canvas fingerprint generated by drawing shapes and text to a hidden canvas element and hashing the result. All values are combined and hashed with SHA-256 to produce the single combined fingerprint shown at the top. Nothing is sent to any server.
A combination of technical signals your browser exposes — user agent, screen resolution, timezone, canvas rendering, WebGL renderer — that websites can combine into a unique identifier to track you without cookies.
No. Everything is read and hashed inside your browser. Nothing is sent to any server or stored after you close the tab.
A page draws hidden shapes to an invisible canvas element and reads the image. Small rendering differences across devices produce a unique output used to identify browsers without cookies.
All signals combined and hashed into a single value. If it changes between loads, your fingerprint has changed.
No. A VPN hides your IP but does not change user agent, screen resolution, timezone, or canvas rendering.
You can reduce it with privacy-focused browsers (Firefox, Brave) or extensions that add noise to canvas and WebGL output. Some signals are difficult to fully hide.
Usually not much. Private mode blocks cookies but your browser's technical signals remain the same. Reload in private mode to compare.
Yes, completely free with no sign-up required and no usage limits.
Everything is computed locally in your browser. Nothing shown here is sent to a server — but this same information is visible to every site you normally visit.
