This QR code generator runs entirely in your browser using JavaScript. When you generate a QR code, the processing happens completely on your device. We never upload your data to any server, which means your URLs, WiFi passwords, contact information, and other sensitive data remain completely private and secure.
Unlike online services that require data uploads, our client-side approach ensures zero data collection, zero server processing, and zero privacy concerns. Your QR code data never leaves your computer.
QR codes can encode various types of data including URLs, plain text, contact information (vCard), WiFi credentials, email addresses, phone numbers, SMS messages, and geographic coordinates. The maximum data capacity depends on the error correction level and complexity of the data.
QR code error correction allows the code to be readable even if partially damaged or obscured. There are four levels: Low (7%), Medium (15%), Quartile (25%), and High (30%). Higher error correction makes QR codes more resilient but increases their size. Use Medium or Quartile for most applications.
For reliable scanning, QR codes should be at least 2cm x 2cm (about 0.8 inches) when printed. Larger QR codes are easier to scan from a distance. Consider the scanning distanceβa QR code on a billboard needs to be much larger than one on a business card. Always test printed QR codes before mass production.
Yes! This tool is completely free with no hidden costs or subscriptions. We believe privacy-first tools should be accessible to everyone.
We use Google Analytics to track page views for website improvement, but we never see, store, or collect your QR code data. All processing happens locally in your browser.
