QR Code Generator Online

QR codes are the fastest way to bridge physical media (like a flyer or a business card) with digital destinations. This tool generates high-quality, scannable QR codes instantly for URLs, Wi-Fi passwords, contact cards, or plain text.

How it works

The generator takes your input string and translates it into a matrix of black and white squares according to the ISO/IEC 18004 standard. It renders this matrix onto an HTML Canvas element locally in your browser, allowing you to customize the colors and download the image.

How to use it

1. Select the type of data you want to encode (URL, Text, Wi-Fi, etc.)
2. Enter your destination link or data
3. The QR code preview updates instantly as you type
4. (Optional) Customize the foreground and background colors
5. Click Download to save the code as a PNG image

A few things worth knowing

• Error Correction: QR codes have built-in redundancy. Even if a small portion of the code is smudged or covered (like placing a logo in the center), smartphones can usually still read it correctly
• Keep it simple: The more text you put into a QR code, the denser and more complex the pixel matrix becomes. A highly dense QR code is harder for older smartphone cameras to scan. For long URLs, consider using a link shortener first
• Never expires: Because this tool generates static QR codes, the data is hard-coded directly into the image itself. The QR code will never "expire" or require a subscription to keep working

FAQ

Why isn't my QR code scanning? Smartphones require high contrast to read the code. Ensure you use a dark foreground color on a light background. Never use a dark background with light squares, as many barcode scanners cannot invert the image mathematically.

Does this track who scans the code? No. Static QR codes do not track analytics. They simply act as a printed string of text that the phone reads. If you need analytics, you must point the QR code to a tracked URL (like a Bitly link) that you control.
