MDH Dynamic QR is a permanently free WordPress plugin for creating and managing dynamic URL QR codes directly on your own website.

Each QR code uses a local short URL on your WordPress installation. This QR redirect points to the current destination URL, so you can change the destination later while the printed QR code stays the same.

Features:
* unlimited dynamic URL QR codes
* destination URLs can be changed at any time
* local QR redirects on your own WordPress domain
* QR code preview
* PNG and SVG download
* print view for browser-based PDF output
* shortcode output
* simple scan counter and last-scan timestamp
* cookie-free counting without storing full IP addresses
* no license key required

The free edition works entirely inside your own WordPress installation. It does not require an external license server, has no time limit, and does not impose a usage quota.

Commercial extensions are separate products and may provide additional QR types as well as media, design, import/export, and analytics tools. The WordPress.org edition does not contain locked premium code.
