Generate a QR code that adds an event to a calendar.
Fill in event title, start, and end to preview your QR code.
An event QR code packs a calendar entry, including title, start and end time, location, and description, into a single scannable image using the iCalendar (VEVENT) standard. When someone scans it, their phone offers to add the event to their calendar, which means your event lands in the one place people actually check: their own schedule.
This free event QR code generator builds that code in your browser. Fill in the event title, pick the start and end times (or tick the all-day checkbox for full-day events), and optionally add a location and description. The tool validates that the end comes after the start, renders a live preview, and downloads the finished code as a PNG. Nothing you type is uploaded or stored anywhere.
Use it on wedding invitations and save-the-date cards, conference badges and session signage, posters for concerts, open houses, webinars, and community meetups. Compared with printing a date people have to copy by hand, a calendar QR code removes the step where most no-shows are born. If the event has a registration page, consider also adding a trackable ReSlug short link so you can measure interest per poster.
Enter the event title. This becomes the headline of the calendar entry people save.
Pick the Start and End using the date and time fields, or check All-day event for full-day entries. The end must come after the start.
Optionally fill in where the event happens and any details attendees need, like a room number or dress code. Both are saved into the calendar entry.
Adjust size, colors, and error correction. Higher error correction is wise for printed invitations that get handled.
Click Download PNG and place the code on your invitation, badge, or poster. Scanning prompts the phone to add the event to its calendar.
Their phone reads the embedded iCalendar event and offers to add it to the default calendar app with the title, time, location, and description already filled in.
The iCalendar format is the cross-platform standard for calendar data. iPhone cameras recognize embedded events directly, while support on Android varies by device and scanner app; some show the raw text and require a dedicated QR scanner to add the event.
The times you enter are interpreted in your local time zone and stored in the code as UTC. Calendar apps then display the event in each attendee's own local time, which keeps the moment consistent worldwide.
No. The event details are encoded directly into the pattern, so changes to the time or venue require generating and printing a new code. People who already saved the event will not see updates either, so include a link to a page you control for events that might move.
No. The code only adds the event to the scanner's own calendar. It does not notify you, collect RSVPs, or share anything back; pair it with a registration link if you need attendance numbers.
There is no fixed limit, but every character makes the QR code denser and harder to scan from print. Keep the description to the essentials and link out for full details.
