What is QR Code Generator?
The QR Code Generator is a free online tool that creates custom QR codes for URLs, text, contact information, Wi-Fi credentials, email addresses, phone numbers, and more — instantly in your browser. QR codes are machine-readable matrix barcodes that smartphones can scan to instantly open links, share contacts, connect to networks, or trigger actions.
This tool generates high-resolution QR codes that you can download as PNG images or SVG vectors, making them suitable for print materials, business cards, product packaging, event posters, restaurant menus, and digital displays.
How Does QR Code Generator Work?
The QR Code Generator uses the QRCode.js library to encode your input data into a standard QR code matrix pattern following ISO 18004 specifications. The library renders the QR code on an HTML canvas element, which is then exported as a downloadable PNG or SVG file. Error correction levels (L, M, Q, H) are supported — higher levels allow the QR code to remain scannable even with up to 30% of the code damaged.

Tips & Best Practices
- Use Error Correction Level H (30%) for QR codes that will be printed on textured or curved surfaces.
- Maintain a minimum size of 2cm × 2cm for printed QR codes to ensure reliable scanning.
- Ensure sufficient contrast between foreground and background colors — avoid light-on-light or dark-on-dark.
- Always test your QR code with multiple devices before printing large batches.
- Use shortened URLs (via bit.ly or similar) to reduce QR code complexity for better scanning.
- Add a call-to-action text near the QR code: 'Scan to Visit' or 'Scan for Menu'.
Common Mistakes to Avoid
- Printing QR codes at sizes below 2cm — they become unscannable at small sizes.
- Using low-contrast color combinations that confuse QR code scanners.
- Not testing the QR code before printing — always verify scanning works first.
- Linking to pages that aren't mobile-optimized — QR codes are mostly scanned on phones.
- Using complex, long URLs without shortening — simpler data = more reliable QR codes.
