17 Open-source Free QR code Generators
A QR code generator is a software application or library that allows users to create Quick Response (QR) codes. QR codes are two-dimensional barcodes that can be scanned using a smartphone or QR code reader, enabling users to quickly access information or perform actions such as visiting a website, sending a text message, or sharing contact details.
QR code generators usually provide options for customizing the appearance and content of the QR codes, such as adding a logo, changing colors, or specifying the type of data to be encoded. They are widely used in various industries for marketing, advertising, inventory management, contact sharing, and more.
