QR Code Generator

The QR Code Generator node lets you quickly create a QR code from any URL, with customizable size, colors, and output format.

Description

This node allows you to generate a QR code image from a given URL. You can customize the QR code’s appearance by adjusting its size, background color, and foreground color. The generated QR code can be exported in different file formats (PNG, JPG, SVG) and output as either an image or a file, depending on how you want to use it. This makes it useful for sharing links, embedding in documents, or integrating into websites and apps.
