Unix Timestamp Converter

What is a Unix Timestamp Converter?

A Unix timestamp converter translates epoch time — the seconds since 1 January 1970 UTC — into human-readable dates. Fontily's accepts seconds or milliseconds, auto-detects which you've entered, and shows ISO 8601, UTC and local time at once.

Features

• Seconds and milliseconds auto-detection.
• ISO 8601, UTC and local date output.
• Instant conversion with clear errors.
• One-click copy for each format.
• Free and private — runs in your browser.

How to Use the Unix Timestamp Converter

1. Paste a Unix timestamp into the box.
2. The ISO, UTC and local dates appear immediately.
3. Copy the format you need.

Benefits

Logs, APIs and databases store dates as timestamps, which are unreadable at a glance. A converter lets developers debug and verify dates quickly, compare UTC and local time, and avoid timezone mistakes.

Use Cases

• Reading timestamps in logs and databases.
• Debugging API date fields.
• Verifying token expiry times.
• Converting epoch values to readable dates.

Conclusion

Fontily's Unix Timestamp Converter turns epoch time into clear ISO, UTC and local dates in an instant. Paste a timestamp above and copy the date you need — free and reliable.
