What is an event QR code generator?

An event QR code generator creates a QR code that, when scanned, opens a calendar prompt with your event details pre-filled. Attendees tap once to save the title, date, time, and location directly into Google Calendar, Apple Calendar, or Outlook — no typing required.

What format does this use?

iCalendar (vCalendar) format, the universal standard supported by Google Calendar, Apple Calendar, Outlook, and more.

Does it account for time zones?

This generates local time without a specific timezone. The scanner's device will interpret it in their local time zone.

Can I use this as an event registration QR code?

Use this event QR code generator when your event registration flow should add the event to a calendar. If the scan should open Eventbrite, RSVP, ticketing, or check-in pages instead, create a link QR with /qr-tools/qr-code-generator.

Can I create a QR code for an event invitation or save-the-date card?

Yes. This is a strong fit for invitations, save-the-date cards, confirmation emails, posters, and agenda signs because the scan opens the event details directly in a calendar flow.

Can I add recurring events?

This tool creates single events only. For recurring events, you would need to add RRULE properties manually.

What happens when scanned?

The phone prompts the user to add the event to their calendar with all the details pre-filled.
