What is QR Code Generator?
A QR Code (Quick Response Code) is a two-dimensional barcode capable of storing various types of data, such as URLs, text, contact information (vCard), or Wi-Fi credentials. Unlike standard barcodes that only hold data horizontally, QR codes hold data both horizontally and vertically, allowing them to store significantly more information. This tool allows you to generate custom QR codes instantly in your browser. You can adjust the error correction level, which allows the code to remain readable even if partially damaged or covered.
