A QR (Quick Response) code is a two-dimensional barcode that stores data like URLs, text, or contact info. It can be scanned by any smartphone camera to instantly access the encoded content.

How do I create a QR code for a website URL?

Select the URL tab, paste your website address, and click Generate. The QR code is created instantly and can be downloaded as a PNG image.

Can I create a QR code for WiFi?

Yes. Use the WiFi tab to enter your network name (SSID), password, and security type. The generated QR code allows anyone who scans it to connect to your WiFi automatically.

Static QR codes (like the ones this tool generates) never expire. The data is encoded directly into the image. As long as the content it points to exists (e.g., a URL is still live), the QR code will work forever.

What size should I print a QR code?

The minimum recommended print size is about 2×2 cm (0.8×0.8 inches) for close-range scanning. For posters or signage meant to be scanned from a distance, scale up accordingly — typically 1 inch per 10 feet of scanning distance.

How QR Codes Work

QR codes (Quick Response codes) were invented in 1994 by Denso Wave, a Toyota subsidiary, to track automotive parts. Today they're everywhere — from restaurant menus to payment systems. A QR code encodes data as a pattern of black and white squares that can be read by any camera-equipped device.

Data Types You Can Encode

QR codes aren't limited to URLs. The standard supports multiple data formats, each triggered by a specific prefix that tells the scanning device how to handle the content.

URL: https://example.com
WiFi: WIFI:T:WPA;S:NetworkName;P:Password;;
Email: mailto:hello@example.com?subject=Hi&body=Hello
Phone: tel:+15551234567
SMS: smsto:+15551234567:Your message here

WiFi QR Codes

One of the most useful applications. When a guest scans a WiFi QR code, their phone automatically connects to the network — no need to type the password. This is especially handy for businesses, Airbnbs, and events. The QR code encodes the network name (SSID), password, and security type using a standard format all modern phones understand.

Example WiFi string:
WIFI:T:WPA;S:CoffeeShop_WiFi;P:Welcome2024;H:false;;
Scanning this connects you to "CoffeeShop_WiFi" with password "Welcome2024".

Error Correction

QR codes have built-in error correction, meaning they can still be scanned even if part of the code is damaged or obscured. There are four levels: L (7% recovery), M (15%), Q (25%), and H (30%). Higher error correction means larger QR codes but more resilience. This generator uses level M for a good balance of size and reliability.

Size and Scanning Distance

For close-range scanning (phone held near the code), a QR code as small as 2 cm works fine. For posters or signage, the rule of thumb is about 1 inch of QR code size per 10 feet of scanning distance. The "Large" and "XL" size options produce higher-resolution images suitable for printing.

Select the URL tab, paste your website address, choose a size, and click Generate. Download the result as PNG and use it anywhere — print, digital, social media.
Yes. Use the WiFi tab, enter your network name, password, and security type. Anyone who scans the QR code will be able to connect to your network automatically.
Static QR codes never expire. The data is encoded directly into the image. As long as the content it links to is still accessible, the QR code will keep working indefinitely.
At minimum about 2×2 cm for close-range scanning. For posters or signs, about 1 inch per 10 feet of scanning distance. Use the Large or XL size option for print-quality images.
Yes. The QR code is generated entirely in your browser using JavaScript. No data is sent to any server. Your URLs, WiFi passwords, and other content never leave your device.
