What is a QR Code Generator?

A QR Code Generator is a digital tool that allows you to create QR codes within seconds. By entering text, URLs, contact details, Wi-Fi credentials, or any type of data, you can generate a scannable QR code. These codes can then be downloaded in different formats (PNG, SVG, EPS, etc.) and used in print or digital mediums.

Unlike traditional barcodes, QR codes can store a huge amount of information and be scanned in any direction. The generator tool makes the process extremely simple — you just provide the data, customize the design, and instantly get a QR code ready to use.

How Does a QR Code Generator Work?

A QR code generator follows three simple steps:

Input Data – You enter the content you want the QR code to display (website URL, phone number, business card, payment link, etc.).
Code Creation – The tool converts this data into a two-dimensional matrix of black-and-white squares, readable by QR scanners and mobile cameras.
Customization & Download – Most modern QR generators let you add logos, colors, shapes, and styles to make the QR code unique to your brand.

The entire process takes less than a minute, yet it provides a powerful way to share information.

Types of QR Codes You Can Generate

QR Code Generators are versatile, allowing you to create different types of codes depending on your needs. Some common types include:

URL QR Code – Redirects the user to a website link.
Text QR Code – Displays plain text when scanned.
vCard QR Code – Shares contact details instantly.
Email QR Code – Opens a pre-written email.
Wi-Fi QR Code – Connects to a Wi-Fi network without typing a password.
Payment QR Code – Used in mobile payments (UPI, PayPal, Stripe, etc.).
App Download QR Code – Redirects users to app stores.
Social Media QR Code – Links to your social profiles.
