QR Code Generator creates scannable QR codes for your WordPress content. Each post, page, or WooCommerce product gets a compact short URL (<code>/go/{base36}</code>) that 301-redirects to the original permalink.
Key Features:
<ul>
<li>Pure PHP QR code engine — no external APIs, no JavaScript rendering</li>
<li>Short URLs via <code>/go/{base36}</code> with permanent 301 redirects</li>
<li>Works with posts, pages, and WooCommerce products</li>
<li>Customizable pixel size, quiet zone, and colours</li>
<li>One-click generate, download, and copy from the editor sidebar</li>
<li>Lightweight — only requires the PHP GD extension</li>
<li>ISO/IEC 18004 compliant QR encoding</li>
</ul>
How It Works:
<ol>
<li>Edit any post, page, or product</li>
<li>Find the “QR Code” meta box in the sidebar</li>
<li>Click “Generate QR Code”</li>
<li>Download the PNG or copy the short URL</li>
</ol>
