What this makes
QR codes for a link, some text, a business card, an event, a Wi-Fi network, a place, an email, a text message or a phone number; and other 2D codes, product codes and barcodes: Data Matrix, Aztec, PDF417, MaxiCode, EAN-13, UPC, Code 128, Code 39 and more. Each is drawn to its standard, and the page tells you before you take it away if it may not scan.
Where your code goes
Nowhere. Nothing you type, choose or add is sent to this site or any other, and nothing is kept: not in this browser, not anywhere. Close the tab and it is gone. An image you copy is on your device’s clipboard for as long as your device keeps it there. Read exactly what is stored
Codes are encoded by bwip-js, by Mark Warren, and files are packed by fflate, by Arjun Barrett, both under the MIT licence and both served from this site.
