QR Code Generator
Generate QR codes for URLs, text, email, WiFi networks, and contacts. Customize size and color, then download or share.
Quick Answer
A QR (Quick Response) code is a two-dimensional barcode that can store up to 4,296 alphanumeric characters. QR codes can encode URLs, plain text, WiFi credentials (WIFI:T:WPA;S:network;P:password;;), email links (mailto:), and vCard contact information. Standard QR codes use Reed-Solomon error correction, allowing them to remain scannable even when up to 30% of the code is damaged or obscured.

About This Tool
The QR Code Generator creates scannable QR codes from various types of content. Whether you need a quick link to a website, a WiFi login QR for your office or cafe, an email shortcut, or a digital business card, this tool handles it all in one place.
QR codes (Quick Response codes) were invented in 1994 by Denso Wave for tracking automotive parts. Today they are everywhere: restaurant menus, event tickets, payment systems, and marketing materials. Their ability to store data in a compact, machine-readable format makes them invaluable for bridging the physical and digital worlds.
Supported Content Types
URL is the most common use case. Scanning the code opens the link in the device's browser. Text encodes any plain text message. Email creates a mailto link that opens a pre-filled email draft. WiFi uses the standard WIFI: format that smartphones recognize, allowing one-scan network connections without typing passwords. vCardencodes contact information that can be saved directly to a phone's address book.
Customization and Best Practices
You can adjust the size of the QR code (small for digital use, large for print) and change the foreground color to match your brand. For reliable scanning, always maintain strong contrast between the foreground modules and the white background. Avoid very light colors like yellow or light gray, as scanners may struggle to detect them.
Shorter data produces simpler QR codes that scan faster and at greater distances. For long URLs, consider using a URL shortener first. The generated QR code is a standard PNG image that you can download and use anywhere: print materials, presentations, websites, or social media.
