You can simply include a "text" field where the form filler can add a hyperlink, the normal text field will take a URL as input.
Awesome! Thank you.

Sorry, but this doesn't work. We are a real estate office and send a form so our sellers that has the real estate website pages where their properties are being marketed. There is no hyperlink field, so I made it a text field. However, many of the URLs are long and even though I made it a multiple line field, a hard return gets inserted so when you click on the link, it fails because it is truncated.
You could provide information to your users to use a service like bit.ly to create shorter URLs to submit in their forms.
