Turn Unix timestamps into readable dates, or dates into timestamps. The live timestamp at the top is handy for development, log debugging and API testing — all processed locally.
FAQ
How are seconds and milliseconds told apart?
The tool guesses by length: ~10 digits are treated as seconds, ~13 as milliseconds. Both units are always shown in the result.
Is my data uploaded?
No. Every conversion happens in your browser and is never sent to a server.
