Unix Timestamp Converter
Convert Unix timestamps to readable dates in local, UTC and IST — all in your browser, nothing uploaded.
How it works
- Enter a timestamp — or hit “Now” to use the current time.
- Pick the unit — seconds or milliseconds, whichever your source uses.
- Read every zone — local, UTC, IST and ISO 8601, each copyable with one click.
Private by design
The conversion is pure browser math using your device’s built-in date handling, so nothing is uploaded. A Content-Security-Policy blocks the page from talking to any third-party server, and the tool keeps working offline once loaded. Read more in our privacy policy.
Frequently asked questions
What is a Unix timestamp?
A Unix timestamp is the number of seconds (or milliseconds) that have elapsed since 1 January 1970 UTC, the Unix epoch. It's a compact, timezone-free way to represent an instant in time.
Seconds or milliseconds?
Both are common: Unix tools and many APIs use seconds, while JavaScript's Date.now() uses milliseconds. Use the unit switch to tell the converter which one you pasted.
Which timezones are shown?
Your browser's local time, UTC, IST (India Standard Time, UTC+5:30) and the ISO 8601 string, so you can read the same instant across zones at a glance.
Is anything sent to a server?
No. The conversion uses your browser's built-in Date handling and runs entirely on your device. A Content-Security-Policy blocks the page from making any network calls.
Is it free?
Completely free, with no sign-up and no limits.
