Just right-click on the QR code and save it either as a SVG or PNG (“image”):
A "quiet zone" is the white border around the QR code. The quiet zone is used to buffer the code from its surroundings to prevent any adjacent images or text from being interpreted as part of the code image itself and interfering with the scanning of the code. Increasing it can improve the readability/"scannability" of a QR code for some QR code readers.
