Convert Unix timestamps to human-readable dates and back online for free. Supports seconds and milliseconds, local time and UTC. No signup required.
First time here? Paste a Unix timestamp or pick a date Your input is processed locally and disappears when you close the tab.
Every developer eventually stares at a number like 1765432100 in a log file or API response and wonders what moment it represents. Our free Unix Timestamp Converter translates epoch timestamps into human-readable dates — and dates back into timestamps — instantly, showing both your local timezone and UTC.
The tool auto-detects whether your value is in seconds or milliseconds (the classic JavaScript gotcha) and converts accordingly, with a manual override when you need it. A live readout of the current Unix time in both units is always one click from your clipboard, handy for crafting API requests and test fixtures.
Timestamps appear everywhere: JWT exp claims, database rows, cron debugging, cache headers, analytics events. Because conversion happens locally, the tool works offline and never sees your data. Decode token timestamps in context with our JWT Decoder, or inspect timestamped payloads with the JSON Formatter.
