Frontpage websites require transfer to another application

I am limited in my ability. I created 3 popular MSFrontpage websites which are still running. Microsoft have pulled the plug on Frontpage. I am still using an old version of it. I know I will need to change soon before Frontpage is totally unusable.

Frontpage was free but I suspect other applications may cost me. Can anyone supply me with a solution. I want to continue my 3 HTML websites. Is there something that I can simply transfer my Frontpage sites to??
