This tool generates QR codes (2D) and 1D barcodes directly in the browser. QR codes store text, URLs, or other data in a two-dimensional matrix readable by any camera. 1D barcodes (Code 128, EAN-13, UPC-A, Code 39) encode numeric or alphanumeric data in vertical bars. Everything is processed client-side — no data is sent to any server.

Example: the text "https://edcilo.com" generates a scannable QR code.
