About QR Code Generator

QR codes (Quick Response codes) are two-dimensional barcodes that can store various types of data including URLs, text, contact information, and WiFi credentials. Invented in 1994 by Denso Wave for tracking automotive parts, QR codes have become ubiquitous in modern life for payments, marketing, authentication, and information sharing. This tool generates QR codes entirely in your browser — no data is sent to any server. The generated codes can be scanned by any smartphone camera or QR code reader app.

Frequently Asked Questions

What is a QR code?

A QR code (Quick Response code) is a two-dimensional barcode that can store various types of data such as URLs, text, contact information, WiFi credentials, and more. Unlike traditional barcodes, QR codes can store much more information and can be scanned quickly from any direction using a smartphone camera.

Is my data safe when using this QR code generator?

Yes, absolutely. All QR codes are generated entirely in your browser using JavaScript. No data is sent to any server, stored, or logged. Your information remains private and secure on your device.

What content types can I encode in a QR code?

This tool supports five content types: Text or URL (opens a web page), WiFi network (connects devices automatically), Email (pre-fills recipient, subject, and body), Phone number (initiates a call), and plain text. Choose the type that best fits your use case.

Can I customize the appearance of my QR code?

Yes. You can customize the foreground and background colors to match your branding. You can also choose from three sizes (Small, Medium, Large) depending on where you plan to display the QR code. Note that very light colors may reduce scannability.

Will my QR code still work if part of it is damaged?

Yes. QR codes include built-in error correction, which means they can still be scanned even if up to 30% of the code is obscured, damaged, or covered by a logo. This generator uses a high error correction level for maximum reliability.

What file format are the downloaded QR codes?

Downloaded QR codes are high-quality PNG images with a transparent background, making them easy to use in print materials, websites, presentations, and digital marketing. PNG ensures lossless quality at any size.

Do I need a special app to scan QR codes?

Most modern smartphones can scan QR codes directly using the built-in camera app — no additional software required. Simply point your camera at the QR code and a notification will appear. For older devices, any free QR scanner app from the app store will work.

Is there a limit to how much data a QR code can store?

Yes. A standard QR code can store up to 4,296 alphanumeric characters, 7,089 numeric characters, or 2,953 bytes of binary data. For URLs and short text, this is more than sufficient. If your content exceeds the capacity, the tool will notify you.
