About QR Code Generator
How QR codes work
A 2D barcode that can hold up to ~4,000 characters depending on density level. Camera apps decode them instantly. Error correction means the code still scans even if partially damaged or covered.
Common uses
URLs (instant link from print to web), Wi-Fi credentials, contact cards (vCard format), payment links, app store deep links, ticketing, event check-ins.
Privacy note
This tool sends your input to a third-party QR API (qrserver.com) to render the image. Don’t encode sensitive secrets, private keys, or unique identifiers through a hosted service — use offline QR libraries for those.
