About QR Code Generator
QR codes encode data (URLs, text, contact info) as scannable 2D barcodes. This generator creates QR codes for websites, Wi-Fi sharing, contact cards (vCard), plain text, or any data, scannable by smartphone cameras.
Customization includes size, colors (ensure sufficient contrast for scanning), and error correction level (higher levels allow scanning even if code is partially damaged). Supports PNG (raster) and SVG (vector, scalable) formats.
All generation happens locally using JavaScript QR libraries. No data is transmitted, safe for Wi-Fi passwords, personal contact info, or confidential URLs.
Frequently asked questions
Low (7% recovery) for clean environments. Medium (15%, default) for general use. High (30%) for codes that may get damaged, printed small, or displayed in poor conditions. Higher correction = larger, denser QR codes.
Yes. Change colors, but ensure high contrast (dark on light) for reliable scanning. Avoid low-contrast combinations (light gray on white). You can also embed logos in the center of high error-correction QR codes.
Depends on data type and error correction. Roughly: 4,000+ alphanumeric characters (max), 7,000+ numeric characters. Practical limit is much lower, large QR codes become dense and hard to scan. Keep data concise.
