Free Online QR Code Generator

How to Generate a QR Code
QR codes (Quick Response codes) are two-dimensional barcodes that can store URLs, text, contact information, Wi-Fi credentials, and more. Our free QR code generator creates high-quality codes instantly, with no account or download required.
- Enter your content — type or paste a URL, text message, or any data you want to encode into the input field.
- Select a size — choose from 150×150 to 400×400 pixels depending on your use case. Larger sizes are better for print materials.
- Click "Generate QR Code" — your code appears instantly in the preview area.
- Download the image — save the QR code as a PNG file for use in documents, presentations, business cards, or marketing materials.
QR codes are widely used in marketing, payments, event ticketing, Wi-Fi sharing, and inventory management. Most modern smartphones can scan QR codes using their built-in camera app — no special software required.
Frequently Asked Questions
Do QR codes expire?
Static QR codes (like the ones generated here) never expire. They encode the data directly in the image pattern. However, if the QR code points to a URL and that URL goes down, the QR code will still scan but the link won't work.
Can I customise the QR code colour or add a logo?
This basic generator creates standard black-and-white QR codes. For custom colours or embedded logos, you would need a more advanced tool. However, standard black-and-white codes offer the best scan reliability across all devices.
What's the maximum data a QR code can hold?
A QR code can store up to 4,296 alphanumeric characters or 7,089 numeric characters. For URLs, we recommend keeping them under 300 characters for the best scanning experience. Use URL shorteners for very long links.
