Event QR Code: an invitation that opens in the calendar

Event QR Codes are useful on invitations, talks, conference schedules and posters. The iCalendar/VEVENT format is recognized by many calendar apps, but each app decides how to import the content. The best event QR is clear, short and explicit about start, end and location.

The QR Code is generated in your browser. Content, Wi-Fi, contact and event data are not sent to the server.

What a VEVENT needs to contain

An iCalendar object uses `BEGIN:VCALENDAR`, `VERSION:2.0` and one or more components. For a simple event, `VEVENT` should include `UID`, `DTSTAMP`, `DTSTART` and usually `DTEND` and `SUMMARY`. The tool converts local dates to UTC in the payload to reduce timezone ambiguity.
Long descriptions, lengthy links and speaker lists can make the QR Code too dense. For real events, a robust strategy is to put title, time and location in the VEVENT and direct full details to an updateable page.

Event examples

Simple meeting

Input: Design review · 2026-06-01 10:00 até 11:00 · Sala 3
Expected output: BEGIN:VEVENT DTSTART:20260601T130000Z DTEND:20260601T140000Z SUMMARY:Design review LOCATION:Sala 3 END:VEVENT

Times are serialized in UTC for interoperability.

Printed invitation

Input: Evento presencial com local e descrição curta
Expected output: VCALENDAR + VEVENT com SUMMARY, DTSTART, DTEND, LOCATION e DESCRIPTION

Keep the description short to preserve scanning in small print.

Frequently asked questions

Does an event QR Code automatically add to the calendar?

Usually not without confirmation. Responsible apps show a preview and ask permission to save the event, because events can contain sensitive data or alarms.

How do I avoid timezone issues in an event QR Code?

Use clear times, test on target devices and prefer UTC in the payload when the event does not depend on a specific regional rule. For complex global events, a registration page with detected timezone is often more reliable.
