About QR Codes
A QR code (Quick Response code) is a 2D barcode that encodes text, URLs, or other data into a scannable square pattern. Any smartphone camera can decode one instantly — making QR codes the fastest way to share a link with someone in the same room.
How it works
This tool uses the qrcode library to generate the QR matrix in your browser. The error correction level is set to M (15%) — meaning up to 15% of the code can be damaged or obscured and it will still scan correctly. Higher sizes (512px) are best for print; 256px is ideal for screens.
