MAC Address Formatter
Reformat a MAC address between colon, hyphen and dotted notations.
The same address, different punctuation
A MAC address identifies a network interface, and it is written several ways — colon-separated, hyphen-separated, or in the dotted style some vendors use. Different systems and configs expect different notations, so an address copied from one place often needs reformatting for another. This converts a MAC address between the notations, and can normalise its case, without changing the address itself.
Paste a MAC address and choose the format you need.
Why the notation matters
The frustration this solves is a config or a tool rejecting a perfectly valid MAC address purely because it is punctuated the wrong way — colons where it wants hyphens, or the dotted form where it wants pairs. Reformatting fixes that instantly. It differs from generating a random MAC: that invents a new address, whereas this reshapes one you already have. Consistent formatting also matters when you are comparing or listing addresses, where mixed notations make the same address look like two different ones.
