Unix Timestamp Converter
Convert epoch timestamps to dates and back — seconds or milliseconds, local and UTC.
Free online Unix timestamp converter
The Ajenza Unix Timestamp Converter turns epoch timestamps into human-readable dates and back, right in your browser. Paste a timestamp and it auto-detects whether it is in seconds or milliseconds and shows the date in both your local time zone and UTC. Or pick a date and time to get the matching timestamp. A live current Unix time is always shown at the top, ready to copy. Timestamps are widely used in programming, logs, APIs and databases. Everything is calculated locally — nothing is uploaded.
Is it free?
Yes — completely free, with no sign-up, download or watermark.
Seconds or milliseconds?
Both — it detects the unit from the number's length, and shows both when converting a date.
Do I need to install anything?
No. Everything runs in your browser.
