What happens when someone scans the event QR code?

Their phone reads the iCalendar data and offers to add the event — with title, time, location and notes — to their calendar app.

How are time zones handled?

Your local start and end times are converted to UTC inside the standard iCalendar format, so the event lands at the right moment on any device.

Is my event data uploaded anywhere?

No. The iCalendar event and QR code are generated entirely in your browser; nothing is sent to a server.

Which calendar apps support event QR codes?

Any app that reads iCalendar (.ics) data works, including Apple Calendar, Google Calendar and Microsoft Outlook. The scanner on most modern phones recognises the format automatically.

Should I download the QR code as PNG or SVG?

Use PNG for posts, slides and most print jobs. Use SVG when you need to scale the code large — for a banner or poster — without any loss of sharpness, since SVG is vector-based.

What is the minimum information an event QR code needs?

A title and a start time are enough to create a usable event. End time, location and description are optional but make the calendar entry far more helpful to whoever scans it.

Can one QR code be scanned by many people?

Yes. The code is static and contains the full event, so any number of people can scan the same printed or on-screen code and each add the event independently.

Calendar Event QR Code Generator

A calendar event QR code lets anyone add your event to their phone calendar with a single scan — no typing, no copy-paste, no chasing people to RSVP. It is ideal for posters, flyers, wedding invitations, conference badges and email signatures. Enter the title, time, location and a note, and the tool builds a scannable code you can download and share.

How it works

The tool encodes your event as a standard iCalendar (VEVENT) record — the same .ics format used by Apple Calendar, Google Calendar and Outlook. Your local start and end times are converted to UTC and written as DTSTART and DTEND fields, alongside SUMMARY (title), LOCATION and DESCRIPTION. That text block is then rendered into a QR code. When a phone camera scans it, the operating system recognises the calendar data and offers to add the event directly.

Example

For a launch party:

Field	Value
Title	Gera Tools Launch
Start	12 June 2026, 18:00
End	12 June 2026, 21:00
Location	24 King Street, London

The tool writes these into a VEVENT block, converts the times to UTC, and produces a QR code. A guest scans it and their calendar opens a pre-filled event ready to save — with the right title, three-hour duration and address.

Download the result as PNG or SVG and add it to your invitation. Everything is generated in your browser, so your event details are never uploaded.
