This QR Code Generator lets you create scannable codes for URLs, plain text, WiFi credentials, and email links — all processed entirely in your browser. QR codes follow the ISO/IEC 18004 standard, which defines how data is encoded into a two-dimensional matrix of black and white modules. The tool uses error correction level M by default, which can recover approximately 15% of damaged or obscured data. This makes your codes reliable even when printed at smaller sizes or partially covered by a logo overlay.

You can download your QR code as either PNG or SVG. Choose PNG for quick sharing on social media, messaging apps, or embedding in documents where a raster image is expected. Choose SVG when you need infinite scalability — for example, printing on banners, business cards, or packaging where the final physical size may vary. SVG files are also significantly smaller in file size since they store vector paths rather than pixel data, making them ideal for web use where every kilobyte counts.

When customizing colors, keep in mind that QR code scanners rely on sufficient contrast between the foreground modules and the background. The ISO standard recommends a minimum contrast ratio of 4:1 for reliable scanning. Dark foreground on a light background works best — avoid light-on-light or dark-on-dark combinations, and never invert the colors (light modules on dark background) as many scanners will fail to read them.

The WiFi QR code feature uses the standard WIFI:T:WPA;S:your-ssid;P:your-password;; format recognized by both iOS and Android devices. When a user scans this code, their phone automatically connects to the network without manual password entry. This is especially useful for guest networks in offices, cafes, and Airbnb properties. All WiFi credentials stay in your browser — nothing is transmitted to any server, so your network password remains completely private.
