KoloQR is a free QR code generator with no registration required, unlimited QR codes, no watermark, and free high-resolution downloads. Built for anyone who wants their QR codes to look as good as they work, instead of a plain black and white square, you can generate codes in circle, square, triangle, or hexagon shapes, fully customized with your own colors and a logo placed right in the center. Every code stays 100% scannable no matter which shape or color combination you choose. The tool is designed with real-world business use cases in mind: restaurants creating digital menu codes for tables, freelancers and small businesses adding a scannable link to business cards, brands linking product packaging to more information, and event organizers using codes for invitations and check-ins. Once your QR code is ready, download it instantly as PNG for everyday use or SVG for high resolution printing. There's no signup, no watermark, and no hidden paywall. Just open the site, design your code, and download it.
