What is a Unix timestamp?

A Unix timestamp is the number of seconds (or milliseconds) elapsed since 00:00:00 UTC on 1 January 1970 — a compact, timezone-independent way to represent a moment in time.

Does it handle milliseconds?

Yes. The converter auto-detects whether your input is in seconds or milliseconds, and you can toggle the unit manually too.

Is anything sent to a server?

No. All conversions happen in your browser using JavaScript Date — nothing is uploaded or stored.
