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.

What is the Calendar Event QR Code Generator?

Free calendar event QR code generator. Encode an event title, time, location and description into a QR code that adds the event to any phone calendar. Runs entirely in your browser — nothing is uploaded. It runs free in your browser on Gera Tools, with nothing uploaded.

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.

Where calendar QR codes work best

Printed invitations and flyers. A QR code on a wedding invitation, a conference flyer, or a community-event poster means guests do not have to type in a date, venue name and address manually. They scan once and the event appears in their calendar with all the correct details already filled in.

Conference and event badges. Placing the QR code on a speaker’s badge or on a session’s handout gives attendees a quick way to capture a talk’s time slot and room location. Because the iCalendar block can include a full description, you can even embed the session abstract or a link to speaker notes in the DESCRIPTION field.

Email signatures and digital newsletters. Adding the code as an image in an email lets remote readers add a recurring call or a product launch directly to their calendar from their phone without opening another app or searching for an invite link.

Recurring events. This tool creates a single-instance VEVENT, which suits one-off events well. For recurring events — weekly team syncs, monthly webinars — the iCalendar format supports an RRULE field, but those are more complex to encode; generating individual codes per occurrence and collecting them into a shared .ics file is usually simpler for recurring series.

Tips for reliable scanning

Keep the QR code large enough: at least 2.5 cm × 2.5 cm on print. Use a high error-correction level when the code will be printed on fabric or placed in outdoor conditions where it may get slightly damaged. Test the code on both an iPhone and an Android phone before mass-printing — iCalendar support is universal but the confirmation dialog varies between operating systems. Store the event description to something concise; very long descriptions increase the QR code’s data payload and make it denser, which can reduce scan reliability on small prints.
