Epoch Converter

Convert Unix epoch timestamps to human-readable dates and back.

Epoch Converter is a fast, no-nonsense timestamp tool built for developers, DBAs, and anyone who stares at raw Unix time all day. CONVERT INSTANTLY, BOTH WAYS • Epoch → date: paste any timestamp and get local time, UTC, ISO 8601, and relative time ("in 2 years", "3 days ago") • Date → epoch: pick a date and get seconds and milliseconds, interpreted as local or UTC • Auto-detects the unit — seconds, milliseconds, microseconds, or nanoseconds — from the number's length • Live epoch ticker in the popup; one click copies the current timestamp • Switch between 24-hour and AM/PM display SEE TIMESTAMPS RIGHT ON THE PAGE On domains you choose, epoch values in log viewers, database UIs (phpMyAdmin, admin panels), and API responses are highlighted automatically. Hover one to get the full conversion in a tooltip — click any value to copy it. localhost works out of the box; add the site you're on with one click ("+ add this tab" in the popup) or type any domain, wildcards included. Changes apply to open tabs instantly, and a short welcome page walks you through it on first install. Toggle the highlighting off anytime. RIGHT-CLICK TO CONVERT ANYTHING Select a timestamp or a date string on any page, right-click, and choose "Convert timestamp ⇄ date". BUILT FOR DEVELOPERS A dark, monospace, editor-style UI that feels like home. Copy buttons everywhere. No accounts, no setup. PRIVATE BY DESIGN Everything runs locally in your browser. No data is collected or transmitted — the extension makes zero network requests. The only things it saves are your two settings (time format and highlight on/off).
