How It Works
Enter Your Event Details
Fill in the event title, start and end date/time, location, and an optional description. The title is the only required field — include as much detail as you like. The more you add, the more useful the calendar entry will be for attendees.
Generate and Style
Your QR code generates instantly as you fill in the details. The data is encoded using the standard iCalendar VEVENT format, which is recognized by Google Calendar, Apple Calendar, Outlook, and virtually every calendar application. Customize the design with colors, a logo, or a frame to match your event branding.
Share with Attendees
Download and place the QR code on event invitations, posters, flyers, email newsletters, presentation slides, or your website. When someone scans it, their phone presents the event details with a one-tap option to add it to their calendar — complete with a reminder notification.
Popular Use Cases
Conferences and Summits
Print a QR code for each session in the event program booklet. Attendees scan the sessions they are interested in and the talks appear in their personal calendar with room numbers, speaker names, and time slots — no manual entry needed.
Wedding and Party Invitations
Include an event QR code on printed or digital invitations. Guests scan once and the ceremony date, time, and venue address land in their calendar. No more "What time was that again?" texts. Add directions or a dress code in the description field.
Meetups and Community Events
Share QR codes on social media posts, community boards, or group chats. People scan the code to add the meetup to their calendar instead of trying to remember the date. The location field can include a map link for easy navigation.
Webinars and Online Events
Embed the QR code in a confirmation email or landing page. Registrants scan to save the webinar time and meeting link. Include the Zoom, Teams, or Google Meet URL in the description so it is right there in the calendar event when the time comes.
Classes and Workshops
Teachers and instructors can create QR codes for recurring sessions, exams, or assignment deadlines. Post them in the classroom or share in a course syllabus. Students scan and never miss a due date again.
Appointments and Bookings
Service providers — doctors, consultants, salons — can hand clients a printed QR code with their next appointment details. The client scans it and the appointment shows up in their calendar with the location and any preparation notes in the description.
Tips for Best Results
- Always include both a start and end time. Without an end time, some calendar apps will default to a 1-hour event, which may not be accurate. Explicitly setting the duration avoids confusion.
- Use the location field for the full venue address or a Google Maps link. Many calendar apps turn the location into a tappable link for directions, which is extremely helpful for attendees.
- Put additional context in the description field: agenda, speaker names, dress code, parking info, a meeting link for virtual events, or a link to the event website. This text shows up directly in the calendar entry.
- If your event spans multiple days, set the start date to the first day and the end date to the last day. The QR code will encode the full date range correctly.
- For events in different time zones, note the time zone in the description (e.g., "3:00 PM EST / 12:00 PM PST") since the VEVENT format uses the device's local time by default.
- Test the QR code by scanning it with your own phone and verifying all details appear correctly in the "Add to Calendar" prompt before distributing it.
- Print the QR code large enough to scan from a comfortable distance. For posters and signage, a minimum size of 5 cm (2 inches) is recommended. For handheld materials like flyers or invitations, 2-3 cm works well.
Frequently Asked Questions
Which calendar apps support event QR codes?
The QR code uses the iCalendar VEVENT format, which is an industry standard supported by virtually every calendar application. This includes Apple Calendar (iOS and macOS), Google Calendar (Android and web), Microsoft Outlook, Samsung Calendar, and most third-party calendar apps. When scanned, the phone recognizes the event data and presents a native "Add to Calendar" prompt.
Do attendees need to install an app to scan the QR code?
No. On iPhones running iOS 11 or later, the built-in Camera app reads QR codes and offers to add the event. On Android 10 and later, the default camera app or Google Lens handles it. No third-party QR scanner app is required. The event details appear in a dialog, and one tap saves it to the default calendar.
Can I include a recurring event in the QR code?
The generator creates a single event instance with the dates and times you specify. Recurring events (weekly meetings, monthly gatherings) require iCalendar RRULE fields, which are not included in this generator to keep the QR code simple and universally compatible. For a recurring series, create one QR code for the next upcoming occurrence and let attendees set their own recurrence after adding it.
How do time zones work with event QR codes?
The event times are encoded as entered, without explicit time zone information. When someone scans the code, their phone interprets the time in its local time zone. If your attendees are all in the same region, this works perfectly. For events with attendees across multiple time zones, mention the intended time zone in the description field so there is no ambiguity.
