About Timestamp Converter

Timestamp Converter is a free, private tool by Digital Heroes that runs entirely in your web browser. It converts Unix epoch values to human-readable dates and dates back to epoch, with no sign-up and no server involved. The tool auto-detects seconds, milliseconds, microseconds and nanoseconds by magnitude. Output covers Local time, UTC, ISO 8601 and relative time ("3 hours ago"). A live current epoch counter runs in the panel so you can copy the exact timestamp at any moment. Everything stays on your device: no upload, no tracking, no limits.

What you can do

Convert epoch to date: paste any Unix timestamp and instantly see Local, UTC and ISO 8601 formats.

Convert date to epoch: pick a date and time to get the matching Unix timestamp in seconds and milliseconds.

Auto-detect the unit: the tool recognises seconds, milliseconds, microseconds and nanoseconds automatically.

See relative time: know at a glance whether a timestamp is "5 minutes ago" or "in 2 days".

Copy the live epoch: grab the current Unix time in seconds or milliseconds with one click.

Use current time as input: press "Use as input" to pre-fill the epoch field with the present moment.

How to use Timestamp Converter

Open Timestamp Converter in your browser. No signup or install needed.

To convert an epoch to a date: paste your Unix timestamp into the "Epoch" field. Local, UTC and ISO 8601 results appear instantly.

What does Timestamp Converter do?

Timestamp Converter turns a Unix epoch number into a human-readable date (Local, UTC and ISO 8601) and converts any date back to its epoch value in seconds and milliseconds. It auto-detects whether your input is in seconds, milliseconds, microseconds or nanoseconds, and shows relative time so you can see how far in the past or future the timestamp falls.
