Timestamp ↔ DateTime Converter

Convert Unix timestamps and human-readable date/time locally.

Timestamp ↔ DateTime Converter is a lightweight Chrome extension that helps users convert Unix timestamps and human-readable date and time values quickly and accurately. The extension allows users to convert timestamps in seconds or milliseconds into readable local time or UTC, and to convert selected date and time values back into Unix timestamps. All calculations are performed locally inside the browser using standard JavaScript date functions. This extension does not collect, store, or transmit any personal data. It does not require user accounts, does not track browsing activity, and does not interact with or modify web pages. The tool works entirely offline and only processes values that the user manually enters. Timestamp ↔ DateTime Converter is designed with a clean, modern interface focused on clarity and speed. It is suitable for developers, analysts, system administrators, content creators, and anyone who needs a simple and reliable way to work with timestamps and date-time values directly from the browser.
