## Description <a href="#description" id="description"></a>

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.

**Field and Function:**

1. **Input\***
   * The URL or link you want to encode into a QR code. Example: `https://www.diaflow.io`
   * Use `@` to reference outputs from previous nodes (e.g., AI-generated text, API response, or spreadsheet data).
2. **QR code size**

* Defines the pixel size of the QR code image.
* Select one of the values
* Example: `256px` (common sizes: 128px, 256px, 512px, 1024px)

3. **Background color**

* Choose the background color of the QR code.
* Default: `#FFFFFF` (white).

4. **Foreground color**

* Choose the color of the QR code itself (the squares).
* Default: `#000000` (black).

5. **Output format**

* Select the format of the generated QR code.
* Options: **PNG, SVG**.

6. **Output type**

* Define how the QR code should be returned.
* Options: **Image** (for direct use in workflows) or **Link** (for sharing).

## Example <a href="#description" id="description"></a>

1. Set up node "File creator" with:
   1. Input = Refer to the output of node "Trigger"
