How to make a Event QR code
An event QR code adds your event to someone’s calendar when scanned — title, date, time and location saved in one tap. It cuts no-shows and manual entry for weddings, launches, webinars, gigs and meetings.
Encode the event in the standard VEVENT format, style the code and download a PNG or SVG for invites, posters and tickets. It is a static code that works forever with no account.
Tips for a great QR code
- A clear event title
- Start and end date/time in the correct format
- The location (address or venue name)
- A short prompt like “Scan to add to calendar”
- A test that it saves to both iPhone and Android calendars
Tip: Use VEVENT with DTSTART/DTEND in YYYYMMDDTHHMMSS format.
Frequently asked questions
How does an add-to-calendar QR code work?
It encodes the event in the iCalendar VEVENT format. Scanning it prompts the phone to create a calendar entry with the title, date, time and place already filled in.
What events is it good for?
Weddings and parties, product launches, webinars, concerts, conferences and meetings — anywhere you want people to remember the date without typing it in.
Does it work offline?
Yes — the event details are stored inside the code, so it adds the entry without needing internet.
Is this QR code generator free?
Yes — CalculatorAI's QR code generator is completely free. Create, customise and download as many static QR codes as you want as PNG or SVG, with no signup, no watermark and no scan limit. Static codes never expire. A free account adds dynamic (editable) codes with scan analytics.
Do the QR codes expire?
Static QR codes never expire — the data is encoded in the code itself, so they keep working forever with no account and no fees. Dynamic codes, which you can edit after printing and track, stay live as long as your free account is active.
Need an editable code with scan tracking?
Static QR codes are free forever and never expire. Want to change the destination after printing and see how many people scan — from where and on what device? Create a dynamic QR code and track every scan in the QR Codes dashboard.
