What is a QR Code Generator?
A QR code generator is a tool that creates QR (Quick Response) codes from various types of data. QR codes are two-dimensional barcodes that can be scanned by smartphones and QR readers to quickly access information.
Our free online QR code generator supports text, URLs, contact information (vCard), and Wi-Fi networks. You can customize colors, size, add a logo, and download your QR code as a PNG image. All processing happens locally in your browser — your data is never sent to any server, ensuring complete privacy.
