How to Use

1. Enter Data:

In the Data to Encode field, type the text or URL you want the QR code to contain (e.g., your website address https://your-site.com). This is required.

2. Choose Error Correction:

Select an error correction level (L, M, Q, H). Hover over each option (e.g., M) to see a tooltip explaining how much data it can recover if the QR code is damaged.

Higher levels (Q, H) are more robust but limit the amount of data the QR code can hold.

Medium (M) is recommended for general use.

3. Advanced Options (Optional):

Click Show Advanced Options to customize the appearance:

Box Size: Controls the pixel size of each square module in the QR code. Larger sizes result in a larger overall image.

Border Thickness: Sets the width of the blank "quiet zone" around the QR code (measured in modules). A border is essential for reliable scanning.

Fill Color: Choose the color of the dark modules (usually black).

Background Color: Choose the color of the light modules/background (usually white). Note: High contrast between Fill and Background is crucial for scannability. Stick to dark fills and light backgrounds.

4. Generate / Update:

Click the Generate / Update QR Code button.

The preview area will show a spinner and a "terminal" message while processing, then display your generated QR code.

5. Download / Reset:
