QR Code Generator

How Do I Create a QR Code Online?

Enter a URL, text, email address, phone number, or WiFi network details in the input field and the tool generates a QR code instantly. You can customize the size and download the QR code as a PNG image. The generation happens entirely in your browser using JavaScript — no data is sent to any server.

What Can I Encode in a QR Code?

QR codes can encode URLs (the most common use), plain text, email addresses, phone numbers, SMS messages, WiFi network credentials, vCard contact information, calendar events, and geographic coordinates. The tool provides dedicated input modes for URLs, text, and WiFi to format the data correctly.

How Do I Use QR Codes for My Business?

Print QR codes on business cards to link to your website, on product packaging to provide instructions, on restaurant menus for online ordering, on event materials for registration pages, and on marketing materials for landing pages. QR codes bridge the gap between physical and digital content.

What Size Should My QR Code Be?

For print, a minimum of 2 cm x 2 cm works for close-range scanning. Business cards typically use 2-3 cm. Posters and signage need larger codes — 10 cm or more for scanning from several feet away. For screen display, 200 x 200 pixels is usually sufficient. Always test your QR code at the intended size and distance before mass printing.

What Is the Maximum Data Capacity of a QR Code?

A QR code can store up to 7,089 numeric characters, 4,296 alphanumeric characters, or 2,953 bytes of binary data. For URLs (the most common use case), this means URLs up to about 4,000 characters long. In practice, shorter URLs produce simpler QR codes that are easier to scan from a distance or at small sizes. Use URL shorteners for very long links.
