This online tool can make malicious URLs harmless so they can be safely shared via email, Twitter, or with other security analysts. Basically, the malicious URL string is modified and is made non-functional by relacing some parts of the URL (such as https:// with hxxps[://]), thus the URL string will be non-clickable and will be considered as a simple string. If needed you can revert hxxps[://] URLs to the original unsafe and clickable value.
