QR Code Generator

About QR Code Generator

A QR code (Quick Response code) is a two-dimensional barcode that can store various types of information. This tool allows you to create custom QR codes for URLs, text, WiFi credentials, contact information, and more with extensive customization options.

What is a QR code?

A QR code is a square barcode that can be scanned by smartphones and QR readers to quickly access information. It can store URLs, text, contact details, WiFi credentials, and more. QR codes are widely used in marketing, product packaging, event tickets, and digital payments.

What types of QR codes can I create?

This tool supports multiple QR code types:
• URL/Website - Direct links to websites
• Plain Text - Any text content
• WiFi - WiFi network credentials for easy connection
• vCard - Contact information (name, phone, email, etc.)
• Email - Pre-filled email composition
• SMS - Pre-filled text messages
• Phone - Direct phone number dialing

What is error correction?

Error correction allows QR codes to remain readable even if partially damaged or obscured. Higher error correction levels make the QR code more resilient but also larger:
• Low (7%) - Smallest size, least damage tolerance
• Medium (15%) - Recommended for most uses
• Quartile (25%) - Good balance for outdoor use
• High (30%) - Best for QR codes with logos or high-risk environments

Can I add a logo to my QR code?

Yes! You can add a logo or image to the center of your QR code. Use high error correction level (Quartile or High) when adding logos to ensure the QR code remains scannable. Keep the logo size reasonable (20-30% of QR code size) for best results.

What size should my QR code be?

The ideal QR code size depends on scanning distance:
• Business cards: 0.8-1 inch (2-2.5cm)
• Flyers/posters: 1.2-2 inches (3-5cm)
• Billboards: 4+ inches (10+ cm)
• Digital displays: 300-500 pixels
General rule: QR code size should be at least 10% of scanning distance.

What format should I download?

• PNG - Best for digital use (websites, emails, presentations)
• SVG - Vector format, ideal for printing and scaling without quality loss
For print materials, always use SVG or high-resolution PNG (1000px+) to ensure sharp, scannable results.

How much data can a QR code store?

QR code capacity depends on the data type and error correction level:
• Numeric only: up to 7,089 characters
• Alphanumeric: up to 4,296 characters
• Binary/UTF-8: up to 2,953 bytes
• Kanji/Japanese: up to 1,817 characters
Longer content creates larger, more complex QR codes that may be harder to scan.

Are the generated QR codes free to use?

Yes! All QR codes generated by this tool are completely free to use for personal and commercial purposes. There are no restrictions, watermarks, or hidden fees. You own the QR codes you create.
