URL Defang / Undefang

Mask suspicious URL dots and protocol markers for safe sharing, then restore them when you need the original link.

Input

Output

Ready to defang or undefang.

Options

Pick what should be masked when you press Defang.

Defang parts

Dots — example.com becomes example[.]com Protocol — http becomes hxxp Protocol separator — http:// becomes http[://]

How the protocol options behave

The two protocol options need a full URL. If the input has no :// — for example a bare hostname such as example.com — the tool reports an error instead of producing a misleading result. Undefang always reverses every combination, so it needs no options.
