The QR Code Generator creates scannable QR codes for any text, URL, or data directly in your browser. Perfect for sharing website links, contact information, Wi-Fi passwords, or any text-based data in a machine-readable format. Customize the foreground and background colors to match your brand, choose from multiple sizes, and download the result as a high-quality PNG image. All generation happens locally in your browser using HTML5 Canvas - no server processing, no data collection, and no usage limits.
Type or paste the content you want to encode into a QR code. This can be a website URL, plain text, email address, phone number, or any other text-based data. URLs should include the protocol (https://) for best scanner compatibility.
Select your preferred QR code size (128px, 256px, or 512px) and customize the foreground and background colors using the color pickers. For best scanning reliability, maintain high contrast between the foreground and background colors.
Press the Generate button to create your QR code instantly. The QR code appears in the preview area on the right. You can modify any settings and regenerate as many times as you want.
Click the Download PNG button to save your QR code as an image file. The downloaded image matches the size you selected and is ready to use in print materials, websites, presentations, or any other medium.
QR codes can encode any text-based data: website URLs, plain text, email addresses (mailto:), phone numbers (tel:), SMS messages, Wi-Fi network credentials, calendar events, and geographic locations. The most common use is encoding URLs so people can quickly visit a website by scanning with their phone camera.
The ideal size depends on your use case. For digital screens and websites, 256px is usually sufficient. For print materials like business cards and flyers, use 512px or higher to ensure crisp output at print resolution. The QR code should be at least 2cm × 2cm in print for reliable scanning from a normal viewing distance.
Static QR codes (like those generated by this tool) never expire. The data is encoded directly in the pattern and doesn't depend on any external service. As long as the encoded URL or content remains valid, the QR code will work indefinitely. Dynamic QR codes, which redirect through a service, can expire if the service shuts down.
QR code scanners rely on contrast between the dark modules and light background to read the code. Low contrast (e.g., light gray on white) can cause scanning failures, especially in poor lighting. For reliable scanning, keep the foreground color dark and the background light. Black on white provides the best scanning reliability across all devices.
Yes, this tool generates QR codes entirely in your browser using HTML5 Canvas. No data is sent to any server, and nothing is stored or logged. You can verify this by checking your browser's network tab while generating a QR code - no outgoing requests are made. This makes it safe for encoding sensitive information like Wi-Fi passwords or private URLs.
