Super Cool QRCode

Easily insert QR codes in your blog, with Widget or Shortcode.

Nicola Franchini

QRcdr integrates a complete, intuitive QR code generator into your WordPress site’s frontend. It enables your visitors to create, customize, and download their own static QR codes without leaving your page, turning your website into a practical digital utility.
The plugin is designed for seamless configuration using a native Gutenberg block. From the editor, you can decide which services to offer (URL, Wi-Fi, vCard, etc.), set default colors, and manage the generator’s layout to match your site’s brand identity.
While the free version provides a powerful tool for generating high-quality static codes, QRcdr PRO unlocks advanced marketing features such as dynamic QR codes, scan analytics, and a full subscription system (SaaS).
