RRZE QR provides a simple way to generate QR codes for:
- Posts\
- Pages\
- Arbitrary URLs
The plugin integrates directly into the WordPress backend and allows users to quickly create and download QR codes pointing to the permalink of any published page or post --- or to any custom URL entered via a built-in tool.
-
Generate QR codes for posts and pages:
Adds a "Generate QR" link to the list view ("All Posts", "All Pages") for every published item. -
Download as PNG:
Clicking "Generate QR" returns a ready-to-download PNG file containing the QR code for the permalink. -
Tool section with URL input:
Under Tools → Generate QR, users can enter any URL, validate it, and instantly generate a QR code. -
Client-side rendering:
QR codes are generated directly in the browser via JavaScript --- no server-side processing required. -
Adjustable color schemes:
Users can choose between different color options for the QR code: black on white, white on black, FAU blue on white, and white on FAU blue. -
Lightweight & fast:
Minimal footprint and no external API calls.
In the WordPress backend, the plugin adds a "Generate QR" action link next to each published post or page.
When clicked:
- The permalink of the item is determined.\

If the URL is valid (HTTP status is not 4xxx), the QR code is displayed.
