    About the QR Code Generator

    A QR code is a 2D barcode that encodes up to 4,296 alphanumeric characters. Modern phone cameras scan them natively, making QR codes a one-step bridge from physical to digital — restaurant menus, WiFi credentials, payment requests, event check-ins. This generator produces standards-compliant payloads for every major content type, with full visual customization.

    Use cases

    Frequently asked questions

    How big should my QR code be?

    +

    At least 2 × 2 cm on print. Bigger is always better for scan reliability. Keep 10%+ margin (the 'quiet zone') around the code.

    Will a logo break my QR code?

    +

    No — QR codes use error correction. At Level H (30% recovery) you can cover up to 30% of the code. Keep logos centered and ≤20% of total area.

    Can I track scans?

    +

    Direct QR codes cannot be tracked. If you need analytics, point the QR to a short URL service (Bitly, Rebrandly) and track there.

    What's the difference between error correction levels?

    +

    L (7% recovery) makes the smallest codes. H (30%) makes the largest but tolerates the most damage or logo overlay. M is a good general-purpose default.

    Is my data embedded in the QR?

    +

    Yes — QR codes are fully self-contained. The data is visible on the image. Don't encode secrets in QR codes.
