How to Use the QR Code Generator
QR codes (Quick Response codes) are two-dimensional barcodes that store information in a machine-readable format. They were invented in 1994 by Denso Wave for tracking automotive parts, but today they are used everywhere — from restaurant menus and business cards to event tickets and payment systems.
This generator creates QR codes entirely in your browser. Simply type or paste your content into the text area — a URL, email address, phone number, plain text, or Wi-Fi credentials. The QR code updates in real-time as you type. Use the quick-fill buttons for common formats like email (mailto:), phone (tel:), and Wi-Fi (WIFI:T:WPA;S:NetworkName;P:Password;;).
Customize your QR code by choosing foreground and background colors. You can use the color picker or type a hex value directly. Adjust the image size between 150px and 600px depending on where you plan to use it — smaller for digital screens, larger for print materials.
Once you are satisfied with your QR code, download it as a high-quality PNG image or copy it directly to your clipboard. The downloaded image maintains crisp pixel boundaries for clean scanning. For best results, ensure there is sufficient contrast between your foreground and background colors — dark modules on a light background is the most reliable combination.
Privacy is a key advantage of this tool. Unlike many online QR generators, your text never leaves your browser. Everything is processed client-side using the Canvas API, so there is no server-side processing, no tracking, and no data retention. Your content is entirely yours.

Is my data stored or sent to a server?
No. All QR code generation happens entirely in your browser using client-side JavaScript. Your text or URL never leaves your device — nothing is sent to any server. This makes it completely private and secure.
