Link Extractor allows you to extract all of the URL links in any given text. It can work with plain text, HTML or any other text where there are links inside. I've build it to help me extract the links I use for my affiliates on the channel, where on some, only the full HTML is allowed to be copied.
This tool is provided free of charge and its code can be found together with the rest of my tools on the GitHub repo. However, hosting costs me money and for that, any donation is more than welcomed.
