Why this tool is useful
Use Calendar Event QR Generator when you need to build an iCalendar event payload with explicit UTC start and end times without sending the encoded details to a remote QR service.

Calendar Event QR Generator
Build an iCalendar event payload with explicit UTC start and end times as a standards-compatible QR code entirely in your browser.
Ready. Your working data stays in this browser.
How it works
The browser validates and escapes the structured fields, builds the exact payload, then renders QR modules locally as PNG or SVG. No API, downloader worker or proxy is involved.
Practical example
Encode a bounded UTC calendar event, scan it, and confirm the time before adding it to a calendar.
Validation
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Privacy boundary
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Result passport
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
