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.
QR codes have become increasingly popular in recent years as a versatile tool for sharing information. In this post, we will explore a variety of QR code generator applications and libraries that are available for free and open-source use.
