Complete Guide to QR Codes

What is a QR Code?

A QR (Quick Response) code is a two-dimensional barcode that can store various types of data including URLs, text, contact information, and more. Invented in 1994 by Denso Wave in Japan, QR codes have become ubiquitous in modern life, from restaurant menus to product packaging, event tickets to payment systems.

How to Create a QR Code

  1. Enter your content: Type or paste any URL, text, email address, phone number, or WiFi credentials into the input field.
  2. Customize colors: Choose foreground and background colors that match your brand or design. Ensure high contrast for best scanning results.
  3. Select size: Use the slider to choose QR code dimensions from 128px to 512px depending on your use case.
  4. Generate: Click the "Generate QR Code" button to create your code instantly.
  5. Download: Save your QR code as a high-quality PNG image for printing or digital use.

Frequently Asked Questions

Is this QR code generator free?

Yes, completely free with no watermarks, no limits, and no signup required. Generate as many QR codes as you need.

Do QR codes expire?

Static QR codes (like the ones generated here) never expire. The QR code itself is just encoded data - as long as the destination URL remains active, the code will work forever.

What size should I make my QR code?

For printing: use at least 256px and ensure the printed size is at least 2cm x 2cm. For digital use: 128px-200px is typically sufficient. Larger sizes are better for scanning from a distance.

Is my data safe?

Absolutely. All QR code generation happens directly in your browser. Your data is never sent to any server - it stays completely private on your device.
