vCard Contact QR Generator
Build a compact vCard 3.0 contact from identity and communication fields 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
Create a conference contact card and scan it into a phone contacts app before printing.
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.
