A QR Code (Quick Response Code) is a two-dimensional barcode that can be scanned by smartphones and QR readers to instantly access information, websites, WiFi networks, contact details, and more. QR codes can store URLs, text, email addresses, phone numbers, and other data formats.

How do QR Codes work?

QR codes encode data using black and white pixel patterns arranged in a square grid. When scanned by a smartphone camera or QR reader app, the pattern is decoded to reveal the embedded information — such as a website URL, WiFi credentials, or contact details.

What is a QR Code?

A QR Code (Quick Response Code) is a two-dimensional barcode that stores information in a pattern of black and white squares. When scanned with a smartphone camera or QR reader, it instantly decodes the embedded data — whether that’s a website URL, WiFi password, business card, or payment link.

Unlike traditional barcodes that hold only horizontal data, QR codes store information both horizontally and vertically, allowing them to hold hundreds of times more data. They’re designed for fast scanning and can be read from any angle.

QR Kuz generates all QR codes entirely client-side in your browser. Nothing you type is sent to a server, keeping your data private and secure.

Frequently Asked Questions

What types of QR codes can I create with QR Kuz?

QR Kuz supports 15+ QR code types: Website URL, Plain Text, Email (mailto), Phone Call, SMS, vCard (digital business card), WhatsApp message, WiFi network login, PDF link, App Store/Google Play link, Image link, Video link, Social Media profile (Instagram, Facebook, X/Twitter, LinkedIn, TikTok, YouTube, custom), Calendar Event (Google Calendar), and Custom 2D Barcode data.

How do I make a WiFi QR code?

Creating a WiFi QR code is simple: select “Wi-Fi” from the type grid, enter your network name (SSID) and password, choose the security type (WPA/WPA2, WEP, or None), and optionally check “Hidden network” if applicable. When scanned, the QR code prompts the user to join your WiFi network instantly — no need to type passwords.

Can I download my QR code as an image?

Yes! QR Kuz lets you download your QR codes as high-resolution PNG files suitable for printing, sharing on websites, or using in marketing materials. You can also copy the QR code directly to your clipboard. The size is adjustable from 160x160 up to 512x512 pixels.

What is the difference between static and dynamic QR codes?

Static QR codes encode data directly into the pattern and cannot be changed once generated. They’re free, permanent, and don’t require any tracking service. Dynamic QR codes redirect through a URL that can be updated later and often include scan tracking. QR Kuz generates static QR codes — they’re entirely self-contained, private, and free forever with no ongoing costs.

How do I scan a QR code?

Most modern smartphones can scan QR codes directly from the built-in camera app. Simply open the camera, point it at the QR code, and tap the notification that appears. Alternatively, you can use dedicated QR scanner apps available for both iOS and Android. QR Kuz generates standard QR codes compatible with all QR readers.
