Free event QR code generator
Turn event details into an add-to-calendar QR code. Free, generated entirely in your browser, no signup — download a print-ready file in seconds.
Generated entirely in your browser — nothing you type here is uploaded or stored.
This is a free static QR code — it works forever, but it can't be tracked or edited after download.
Make It Dynamic & Trackable — FreeHow it works
Fill in the event details
Enter the event title, an optional location, the start and end date and time, and an optional short description. The generator assembles them into a standard iCalendar VEVENT.
Watch the code update live
The QR code regenerates in your browser as you type. Nothing is uploaded anywhere — the code is built entirely on your device.
Download as PNG or SVG
Grab a PNG for screens and documents or a print-ready SVG that scales cleanly to any size. No signup, no watermark, no expiration.
Optionally make it editable and trackable
If the venue or time might change, or you want to count scans, create a dynamic version at /create-qr-code. You can edit its content after printing and see scan analytics.
What is a event qr code?
An event QR code puts a calendar entry inside a scannable square. When someone points their phone camera at it, the phone reads the event details — title, location, start and end time — and offers to add the event to the built-in calendar app. Modern iPhone and Android cameras handle this natively; there is no app to install and nothing to type. Instead of hoping people copy a date off a poster correctly, you hand them a one-tap way to save it.
Under the hood, the code encodes plain text in the iCalendar format — the same VEVENT standard that .ics email attachments use. A SUMMARY line carries the title, LOCATION the venue, DTSTART and DTEND the times, and DESCRIPTION any notes. Everything lives inside the pattern itself, so the code works with no internet connection and never depends on a server. The tradeoff is density: the more text you enter, the more modules the code needs, and dense codes are harder to scan at small sizes. Keep the description short.
For print, use dark modules on a light background and leave a quiet zone — a clear margin of at least four module widths — around the code. Because calendar codes carry more data than a simple link, print them a little larger than you would a URL code: 2 cm per side is the practical minimum, and 3 cm is safer on a flyer read at arm's length. Always test-scan the final design with both an iPhone and an Android phone before sending anything to the printer.
Where event qr codes work best
Conference and trade show sessions
Print a code beside each session in the printed program or on room signage. Attendees scan the talks they care about and get the title, room, and time slot saved to their calendar — instead of a photo of the agenda they will never open again.
Wedding save-the-dates and invitations
Add a code to the save-the-date card or invitation insert. One scan puts the ceremony date, venue, and start time on the guest's calendar months ahead. It works offline, so it scans fine the moment the envelope is opened, and guests never mistype the date.
Team schedules and game days
Put a code on the season flyer or a game-day poster so parents and fans save the next match with the field address in the location field. For a full season, print one code per game or link a dynamic code to a schedule page you can update as fixtures move.
Church services and community events
Bulletin inserts, lobby posters, and community boards all work. A code for the potluck, the volunteer day, or the special service lets members commit on the spot. Older congregants do not need an app — the phone camera and calendar handle everything.
Product launches and webinars
Announcing a launch event or webinar on a poster, mailer, or package insert leaves people with a date to remember and no way to click. An event QR code closes that gap: scan, save, and the calendar entry does the follow-up for you. Put the join link in the description field.
Open houses and showings
Add a code to the yard sign rider or listing flyer with the open house date, time, and property address in the location field. Prospective buyers who drive by on Tuesday get a calendar entry that brings them back on Saturday, with the address ready for navigation.
Static code vs. dynamic QR code
- A static calendar code is permanent: the title, venue, and times are baked into the pattern, so a room change or a reschedule means regenerating the code and reprinting every poster.
- Static codes cannot report anything — you will never know how many people scanned or saved the event.
- A dynamic QR code from QRelix points to a destination you can edit anytime after printing, and adds scan counts, device breakdown, geography, and scan-by-hour analytics.
- The free static code from this page keeps working forever; go dynamic when details might change or you need to measure interest.
Frequently Asked Questions
Does an event QR code work on iPhone and Android?
Yes. Modern iPhone and Android cameras recognize calendar data in a QR code and offer to save the event without any extra app. Behavior differs slightly by device: iOS shows an add-to-calendar prompt directly, while some Android phones surface the event details through the camera's lens feature first. Either way, the details transfer without typing. Test-scan on the oldest phones your audience is likely to carry.
Do people need internet to scan a calendar QR code?
No. Everything — title, location, times, notes — is stored inside the code itself as iCalendar text, so the phone reads it entirely offline. That makes event QR codes reliable in convention halls, basements, and venues with weak signal. The only step that may touch the network is the calendar app syncing the saved event afterward, which happens whenever the phone next connects.
Can I change the event details after printing the QR code?
Not with a static code — the details are encoded in the pattern permanently, and a change means generating and reprinting a new code. If the venue, date, or agenda might shift, create a dynamic QR code at /create-qr-code instead: it points to a destination you can edit anytime without touching the printed material, and it records scan analytics along the way. QRelix's free plan requires no credit card.
What information can an event QR code hold?
This generator encodes a title, an optional location, start and end date and times, and an optional description, using the standard iCalendar VEVENT format. That covers everything a calendar entry needs. Keep the description brief: every extra character makes the code denser and harder to scan at small print sizes. Long agendas belong on a web page, not inside the code.
Why does my calendar QR code look denser than a URL code?
Because it carries more text. A URL code stores one short link; a calendar code stores a title, location, two timestamps, and a description, so the QR standard adds more modules to fit the data. Denser codes need more physical size to stay scannable — print at 2 cm per side minimum, larger if you filled in every field, and always test-scan the final artwork.
Is this event QR code generator really free?
Yes. The code is generated entirely in your browser — nothing is uploaded — and you can download it as a PNG or SVG with no signup, no watermark, and no expiration. It is a static code, so it works forever but cannot be tracked or edited after creation. QRelix's paid features apply only to dynamic codes; this tool stays free.
