Unix Timestamp Converter
Convert a Unix timestamp to a human-readable date — UTC, your local time and ISO 8601 — right in your browser. It auto-detects seconds vs milliseconds, and nothing is uploaded.
How to use it
- 1Paste a timestamp
Enter a Unix timestamp in seconds or milliseconds — or click “Now” for the current time.
- 2Read the conversions
See the UTC, local and ISO 8601 representations side by side.
- 3Copy what you need
Copy any of the formatted values with one click.
Epoch time, made readable
A Unix timestamp counts the seconds (or milliseconds) since 1 January 1970 UTC. It’s compact and timezone-free, but unreadable at a glance. Paste one here to see exactly what date and time it represents.
Seconds or milliseconds — automatic
APIs and logs use both 10-digit (seconds) and 13-digit (milliseconds) timestamps. This converter detects which you pasted and converts accordingly. The “Now” button drops in the current timestamp.
Frequently asked questions
Is anything sent to a server?
No. The conversion runs entirely in your browser; nothing is uploaded.
Does it handle milliseconds?
Yes. It auto-detects seconds vs milliseconds based on the value, so both common formats work.
What timezone is shown?
Both UTC and your device’s local time are shown, alongside the ISO 8601 string.
What does the “Now” button do?
It fills in the current Unix timestamp in seconds, so you can read or copy it immediately.
