QR Code Generator Frequently Asked Questions
A QR (Quick Response) Code is a two-dimensional matrix barcode composed of black square modules arranged on a white grid. Created originally in 1994, QR codes store high-density binary, alphanumeric, or numeric data (such as web links, contact vCards, or Wi-Fi credentials) that can be scanned instantly using a smartphone camera.
Static QR codes embed the target data (like a URL) directly into the physical module pattern itself. They cannot be modified after generation, but they never expire, require no server redirect, and run entirely offline. Dynamic QR codes embed a tracker URL pointing to a service provider's remote server. While tracking is possible, dynamic QR codes can expire, often require monthly subscription fees, and pose privacy risks. DuckConvert generates 100% static, free QR codes that last forever.
QR codes use Reed-Solomon error correction, which allows scanners to successfully read the code even if the barcode image is partially scratched, dirty, or covered (up to 30% damage depending on the level). This feature is what allows logo images to be placed in the center of QR codes without breaking their scannability.
Traditional online generators upload your target URLs, confidential contact cards, or corporate network keys to their servers, building tracking profiles of your links. DuckConvert generates all QR patterns locally within your browser sandbox using secure, client-side JavaScript. No data ever travels over the internet, providing perfect privacy.
