Link, Text oder WLAN-Passwort als QR-Code – kostenlos, kein Login, direkt im Browser
A QR (Quick Response) code encodes data — a URL, plain text, contact card, or Wi-Fi credentials — into a two-dimensional matrix of black and white squares. The generator converts your input into this pattern using the ISO/IEC 18004 standard, then renders it as a PNG image you can download, print, or embed anywhere.
Common use cases include sharing website links, restaurant menus, event check-ins, contactless payments, Wi-Fi passwords for guests, business cards, product packaging, and marketing materials. Any smartphone camera released after 2017 can scan a QR code natively — no third-party app required.
For print materials, download at the highest available resolution and ensure the printed QR code is at least 1 inch × 1 inch (2.5 × 2.5 cm). For billboards or large-format prints, scale up proportionally. Always test-scan the printed code before mass production.
A static QR code encoding a URL is permanently valid as long as the destination URL remains live. The code itself never expires — only the link it points to can break. If the URL changes, you'll need to generate a new QR code since static codes cannot be edited after creation.
Yes — enter your network name (SSID) and password in the Wi-Fi QR format (WIFI:T:WPA;S:NetworkName;P:Password;;). Guests scan the code to join your network instantly without typing the password. This works on iOS 11+ and Android 10+ without any app.
