Paste a MAC address in almost any style and this tool cleans it up and shows it in every common format at once: colon separated, hyphen separated, Cisco style dot notation with three groups of four, and bare hex with no separators. It accepts input that uses colons, hyphens, dots, spaces or nothing at all, so you do not have to match a specific input shape. This is handy because different systems and vendors insist on different separators, and retyping a twelve digit address by hand is error prone. It validates that you have exactly twelve hexadecimal digits and flags anything that does not fit. Each output is offered in both uppercase and lowercase so you can match your target system exactly. Everything runs locally in your browser, so the hardware address you enter is never uploaded or stored.
