How to use QR Payload Inspector

Count UTF-8 bytes and identify common QR payload prefixes.

  1. Enter the required text, URL, payment address, or barcode content.
  2. Run the generator or analyzer.
  3. Preview and download the result, then test it before distributing.

QR generation supports at most 106 UTF-8 bytes at error correction level L (versions 1–5). Image scanning requires a compatible browser with BarcodeDetector support and runs locally in the browser; it is not supported everywhere. Never trust or pay an unverified recipient just because a QR code parses.
