Browser Fingerprint

Generate a report only when you click Inspect. Basic inspection reads browser identification, language, time zone, display and limited hardware hints. Extended checks are off by default.

Optional extended checks (expose additional signals) Canvas drawing and pixel digest WebGL and GPU information Audio offline audio digest (no recording/playback) Candidate font check (approximate matches)

Click Edit above to enable changes and hash selection, then Edit beside a value to change it and its type. An * after a name marks a user-provided or edited value. Checkboxes control hashing only; exported reports still include all values, original detections and source labels. Delete removes a field from the current report and hash; reinspection or Restore brings detected fields back. Manual values do not change your browser or hardware.

Ordinary web pages cannot reliably read MAC addresses, CPU serials or IMEI. These fields are user-provided only and excluded from hashing by default.

Full report (JSON, sources and hash input)

Reports and digests stay in page memory, never uploaded or put in URLs/persistent browser storage. Clearing, refreshing or leaving removes them. Manage explicitly copied/exported reports yourself. Optional completion counts contain only fixed tool/action/basic-or-extended mode, never signals or digests.

Understanding the result

Click Inspect to generate a local report. Canvas, WebGL, offline Audio and candidate font checks are optional and off by default. Re-run to compare snapshots in this tab. The summary is not a globally unique identifier, tracking test or privacy score.

Browsers may restrict, normalize or randomize signals; missing fields are not necessarily abnormal. Only selected field names, typed values and the summary schema version participate. Inspection time, unselected fields, inspection options and source labels do not. Equal selected values produce equal digests; editing an unchecked field leaves the digest unchanged. Matching digests do not prove the same person, nor do different digests prove different people. Without a cross-user dataset, this tool cannot calculate uniqueness, population entropy or a privacy score.

Cookie enabled reflects a reported setting, not a test of third-party cookie access. Hardware/platform signals may be approximate or spoofed. Audio renders a fixed offline graph without recording or playback. Font checks compare a fixed candidate list against generic fallback measurements; substitutions and browser protections can cause errors, and this is not a complete installed-font list. No camera, microphone, location or local-font-access permission, WebRTC/IP lookup or remote matching is used. Reinspection replaces detected values while retaining in-tab manual fields and selections. Restore resets detected values only; Clear removes everything.
