QR Code Generator

1. Enter text or URL. You can encode website links, plain text, contact data, Wi-Fi credentials, or any other QR-compatible payload.
2. Customize the configuration. Adjust the output size, quiet-zone margin, and error correction level to fit your scanning and print requirements.
3. Download the PNG. The QR code updates in real time while you edit, and you can save the final image with one click.

• For URLs: The QR code typically opens the target link when scanned.
• For plain text: Scanning displays the encoded message directly on the device.
• For contact information: Use a valid vCard payload for better compatibility.
• For Wi-Fi credentials: Use the format WIFI:T:WPA;S:SSID;P:password;;.

• Generate QR codes from text or URLs without requiring signup or installation.
• Customize size for compact embeds or large printable outputs.
• Adjust quiet-zone margin to improve scan reliability across different layouts.
• Choose an error correction level from L, M, Q, or H depending on your tolerance for damage or obstruction.
• Download PNG output for reuse in documents, presentations, packaging, or signage.
• Preview changes instantly as you edit the payload or settings.

This tool uses JavaScript to generate QR code matrices and the browser canvas API to render the final image. Everything happens locally in the page, which keeps generation fast and avoids sending your data to a server.

• Rejects empty input and prompts for text or a URL before generation.
• Surfaces payload-length errors when the selected correction level cannot fit the content.
• Lets you recover by shortening the input or changing configuration values.

• 100% client-side processing: QR code generation happens in your browser.
• No data storage: your text is not uploaded or persisted by the tool.
• Works offline after the initial page load in capable browsers.
• No external services are required at generation time.

The tool works in modern browsers that support:

• HTML5 Canvas API
• File download support for PNG export
• ES6+ JavaScript features
