QR Codes Explained — How to Create and Use QR Codes for Everything

QR codes (Quick Response codes) are everywhere — restaurant menus, business cards, event tickets, and product packaging. But how much do you really know about them?

What is a QR Code?

A QR code is a 2D barcode that can store:

• URLs — link to websites
• Text — any plain text information
• WiFi credentials — network name and password
• Contact info — vCard format for business cards
• Email addresses — pre-fill recipient and subject

How to Create a QR Code

Creating a QR code is simple with our free QR code generator:

1. Choose a type — URL, text, WiFi, email, or phone
2. Enter your data — paste the URL or type your content
3. Customize — adjust size and error correction level
4. Download — get your QR code as PNG or SVG

QR Code Best Practices

• Test before printing — scan the QR code to verify it works
• Use high contrast — black on white works best
• Add quiet zone — leave white space around the QR code
• Consider error correction — Level H (30%) for printed codes
• Keep it simple — shorter URLs = smaller, faster-scanning codes

Creative Uses for QR Codes

• Business cards — link to your portfolio or LinkedIn
• WiFi sharing — let guests connect without typing passwords
• Event tickets — scan for check-in
• Restaurant menus — link to digital menu
• Product packaging — link to user manuals or tutorials
