Online QR code generator

A QR code is a two-dimensional barcode designed for quick reading of information by a mobile phone camera. The QR code generator allows you to quickly and freely encode any information: free text, URL link, email. In the settings you can select the size of the code, as well as its background.

QR codes (Quick Response codes) are one of the most popular and widely used types of two-dimensional barcodes in the modern world. They are matrix codes that contain information arranged in two dimensions. The QR code generation algorithm determines how these codes are created and subsequently interpreted.

QR Code Generation Process

Data Type Determination

QR codes can contain various types of data, such as text, URLs, contact information, phone numbers, and more. The first step in the QR code generation algorithm is to determine the type of data that will be encoded in the QR code.

Data Encoding

Next, the data is transformed into a special format that can be interpreted by QR scanners. This involves using specific encoding algorithms, such as the Bayer-Reed algorithm for encoding numerical data, alphanumeric encoding algorithms, and others.

QR Code Image Generation

The following step is to create a physical representation of the QR code, which can be printed or displayed on a screen. Typically, a QR code is a square matrix of black and white cells representing the encoded data.
