About QR Code Generator
The QR Code Generator is an interactive client-side utility designed to create custom QR (Quick Response) codes. QR codes are widely used for sharing websites, contact information, wifi credentials, and payment links. Our tool lets you generate custom QR codes, customize their colors and sizes, and download them as PNG images—all processed locally to keep your data private.
How it Works
Type your URL or text into the input box. The tool generates the QR code instantly. You can customize the foreground and background colors using the color pickers, and click the download button to save the QR code as a PNG image.
Key Features
- Instant Generation: QR code updates dynamically as you type.
- Color Customization: Set custom foreground and background colors.
- PNG Downloads: Save your QR code in high resolution.
- Secure & Local: All generation happens in your browser.
Technical Details
The generator uses our custom, lightweight client-side QRCode library in TypeScript. It encodes the input text into a boolean module grid, renders the grid onto a canvas using the selected colors and scale factor, and generates a downloadable PNG base64 stream.
