About This Tool
What is a QR Code?
A QR (Quick Response) code is a 2D barcode readable by phone cameras. Used for sharing links, contact info, Wi-Fi networks, and text. Can store up to 3,000 characters.
How Does a QR Code Work?
It stores data in a pattern of black and white squares. The camera reads this pattern and converts it to text or a link. Larger codes store more data and are easier to scan from a distance.
Practical Uses
- Digital business cards and contact sharing
- Restaurant menus and online stores
- Website links and social media pages
- Event tickets, concerts, and conferences
- Sharing Wi-Fi passwords easily
Tip: Test QR codes before printing. Use larger sizes (300+ px) for print and smaller for screens. Ensure sufficient contrast for easy scanning.
