To get a web address to convert to a clickable link, the best way is to start each with either http://, https://, ftp:// or www.
For example
http://google.com
https://google.com
ftp://google.com
www.google.com

Apart from what you have above, we will like to let you know that our system is quite smart. So other text that looks like links will also be converted. for example "google.com/search"; will be converted. but note that "google.com" will not be converted because it doesn't look very much like a link

Sometimes a valid link will not be converted. If you wish to display a valid link without it being converted, use the fancy mode

Each paste may have a maximum of 170,000 characters.
