CodingMarble QR & Barcode is a free set of QR code and barcode tools made by CodingMarble, the team behind Calculator, LovePDF and LoveImage.
Every code is generated inside your web browser using the open QR code (ISO/IEC 18004) and barcode standards. We don't ask you to sign up, we don't add watermarks, and the codes never expire because they don't depend on our server.
