QR (Quick Response) codes are 2D barcodes that store data in a square grid of black and white squares. When scanned by a camera, the pattern is decoded to reveal the embedded information like URLs, text, or contact details. QR codes can hold up to 4,296 alphanumeric characters and use Reed-Solomon error correction to remain readable even when partially damaged.
Error correction allows QR codes to be read even when damaged, dirty, or partially obscured. There are 4 levels: L (Low ~7%) - basic protection, M (Medium ~15%) - standard use, Q (Quartile ~25%) - industrial environments, and H (High ~30%) - maximum protection. Higher levels create larger QR codes but ensure better reliability in harsh conditions.

Yes! You can upload your brand logo (PNG, JPG, or SVG up to 2MB) and customize its size from 10-30% of the QR code. The logo is placed in the center with a background circle to ensure scannability. Logo integration is currently supported for PNG format downloads.
Enter your UPI ID (like yourname@paytm), payee name, amount (optional), and transaction note. The generated QR code follows UPI standards and works with all major Indian payment apps. Customers can scan and pay instantly without typing details manually.
Static QR codes (like ours) have data embedded directly in the code - they never expire, work offline, and can't be tracked or changed. Dynamic QR codes redirect through a URL shortener, allowing content updates and analytics but require internet and may expire if the service stops.
Most smartphones have built-in QR scanners in their camera apps. Simply open your camera, point it at the QR code, and tap the notification that appears. For older phones, download a QR scanner app from your app store.
QR codes themselves are safe, but always verify the destination before taking action. Malicious QR codes can redirect to phishing sites or trigger unwanted downloads. Only scan codes from trusted sources and check the preview URL before proceeding.
Static QR codes (like the ones generated here) never expire and work forever without internet. The data is permanently encoded in the visual pattern itself, making them reliable for long-term use in print materials, business cards, and signage.
The minimum recommended size is 2x2 cm (0.8x0.8 inches) for reliable scanning. For business cards, use at least 1.5x1.5 cm. For posters or signage, ensure the QR code is large enough to scan from your intended viewing distance - roughly 10:1 ratio (10cm viewing distance needs 1cm QR code).
Yes! You can choose from 8 preset color schemes or create custom combinations using our color picker. Ensure sufficient contrast between foreground and background colors for reliable scanning - dark patterns on light backgrounds work best.
Our generator is completely free, works offline in your browser (no data sent to servers), supports 9 different QR types, offers logo integration, provides multiple download formats, includes comprehensive error correction options, and generates high-quality codes suitable for both digital and print use.
