How RFC 5545 iCalendar (VEVENT) Format Works: Standards & Compatibility
Event QR codes encode calendar events using the universal iCalendar standard (BEGIN:VEVENT ... END:VEVENT). Mobile operating systems recognize this payload to present an 'Add to Calendar' prompt pre-populated with title, start and end timestamps, venue location, and event description.
BEGIN:VEVENT SUMMARY:Product Launch Keynote DTSTART:20261015T180000Z DTEND:20261015T200000Z LOCATION:Grand Ballroom, Center Hall DESCRIPTION:Annual keynote unveiling new products. END:VEVENT

Printing & Quality Guidelines
Follow these ISO/IEC 18004 recommendations to ensure instant, frictionless scans:
Maintain strong contrast: ensure dark foreground elements on a clean light background.
Observe the Quiet Zone: leave at least 4 modules of blank white margin around the QR code.
Test before bulk printing: scan the physical printed sample on both iOS Camera and Android Google Lens.
Use vector SVG for print production: SVG scales infinitely without pixelation on large signage or menus.
100% Client-Side Privacy Guarantee
QR Studio never stores, tracks, or analyzes your input payload. All matrix math, Reed-Solomon error correction encoding, and image rendering occur directly in your browser.
Frequently Asked Questions
Does the calendar event automatically remind the user?›
Once saved to the user’s calendar app, their phone’s default notification settings (e.g. reminder 15 minutes or 1 day prior) will automatically trigger.
What time zone should I use when setting the event time?›
QR Studio converts your local event date and time into universal UTC (Zulu) timestamps (YYYYMMDDTHHMMSSZ), which mobile calendars automatically convert to each attendee’s local time zone upon saving.
Can I include a venue address or virtual link in the description?›
Yes! Both physical street addresses and virtual video call links (Zoom, Google Meet, Teams) can be included in the location or description fields.
Is any event data stored on QR Studio servers?›
No. The entire iCalendar string is processed directly inside your browser memory. We have zero access to your event schedules.
