QR Code Generator

What Can You Encode in a QR Code?

QR codes (Quick Response codes) can store any short string of text. The most common uses are:

• Website URLs — link people to a page without typing a long address
• Contact information — vCard format for phone, email, and name
• Plain text — short instructions, event details, or messages
• Email addresses — mailto:name@example.com
• Phone numbers — tel:+1234567890
• Wi-Fi credentials — WIFI:S:NetworkName;T:WPA;P:password;;

How to Use

1. Type or paste your URL or text into the input box.
2. Optionally adjust the size and colors.
3. Click Generate QR Code.
4. Click Download PNG to save the image.

The QR code is generated instantly in your browser using a built-in encoder. No external services or APIs are involved.

QR Code Best Practices

For print materials like flyers, posters, or business cards, use at least 300 × 300 pixels and keep the quiet zone (white border) intact — it helps scanners read the code reliably. Dark modules on a white background have the highest contrast and scan best. Always test the QR code with a phone scanner before printing.

For digital use (websites, presentations, emails), any size works as long as the image is sharp and not compressed too heavily. Use PNG format (which this tool provides) rather than JPEG to avoid compression artifacts that can interfere with scanning.
