WebKit Timestamp Converter
Convert Chrome and WebKit browser timestamps to human-readable dates
What is a WebKit Timestamp?
WebKit timestamps count microseconds since January 1, 1601 UTC. They are 17-digit integers used internally by Chromium-based browsers (Chrome, Edge, Opera) to track timestamps in cookies, browsing history, downloads, and local storage.
Where You'll Encounter WebKit Timestamps
Chrome's SQLite databases (History, Cookies) store all timestamps in this format. The Cookies database uses it for expiry times and last access times. The History database uses it for visit timestamps and download times. Forensic analysis of browser data frequently involves converting these timestamps.
How to Convert
Paste any 17-digit WebKit timestamp into the converter above. Chronoshift automatically detects the format and converts it to human-readable dates, Unix timestamps, and ISO 8601 format with one-click copy buttons.
