Overview
Instant epoch converter in a popup — no new tabs, no clutter. Convert timestamps, view boundaries, and more.
Epochsy is a lightweight epoch timestamp tool built for developers. It lives in your toolbar as a simple popup — no new tabs, no clutter, no distractions. WHAT IT DOES • Convert — Paste an epoch (seconds or milliseconds) or a date string. Auto-detects the format and instantly shows local time, UTC, epoch seconds, and epoch milliseconds. • Live Clock — See the current Unix timestamp updating in real time. Seconds, milliseconds, local, and UTC — all at a glance. • Bounds — Pick a date and period (Day, Month, or Year) to get the exact start and end timestamps. Great for API queries, log filtering, and database ranges. • Duration — Enter a number of seconds to break it down into years, months, days, hours, minutes, and seconds. • Info — Quick reference on what epoch time is and why it's used. WHY EPOCHSY? → Popup-only — never opens a new browser tab like other converters → Zero permissions — no access to your tabs, history, or data → Fully offline — no network requests, ever → One-click copy on every value → Auto dark mode → Remembers your last used mode → Keyboard navigable Built with vanilla JavaScript, no frameworks, ~11KB total. Fast, private, and focused. Perfect for backend engineers, frontend developers, QA testers, DevOps, and anyone who works with Unix timestamps daily.
