QR Code Generator

What is a QR Code Generator?

A QR (Quick Response) code is a two-dimensional barcode that stores data — most commonly a URL — in a pattern of black and white squares that smartphone cameras can scan instantly. A QR code generator encodes your text or link into that pattern so anyone can reach your content with a quick scan, no typing required.

Our QR Code Generator creates the code entirely in your browser and lets you download it as a crisp PNG image at the resolution you choose, ready to use on websites, business cards, posters, packaging, and presentations.

How to Generate a QR Code

• Enter a URL or any text in the content field
• Adjust the size slider for the resolution you need (up to 1024px for print)
• Choose an error-correction level — higher levels survive damage or logos
• The QR code preview updates instantly as you type
• Click Download PNG to save the image to your device

Understanding Error Correction

QR codes include built-in error correction, which lets them still be scanned even if part of the code is dirty, damaged, or covered. There are four levels: Low (recovers about 7%), Medium (15%), Quartile (25%), and High (30%).

Higher error correction makes the code more robust but also denser. For digital use, Medium is a good default. For printed materials that may get scuffed — or when placing a logo over the center — choose Quartile or High for reliable scanning.

Common Uses for QR Codes

Businesses use QR codes to link to websites, menus, app downloads, Wi-Fi networks, payment pages, and contact details. Developers embed them in apps for quick pairing and authentication. Event organizers use them for tickets and check-in. Because the code is generated locally in your browser, your data is never sent to a server.
