The fphtml file extension identifies a file used by Microsoft FrontPage, Microsoft's web design application for creating and managing web pages on Microsoft Windows.
An fphtml file can contain the HTML source for a page, along with FrontPage-specific markup or components used by the application. It is part of the files that FrontPage uses when working with a web site.
Microsoft no longer develops FrontPage, so the fphtml format is a legacy format. Existing files may still be usable if the required FrontPage features are preserved.
On Windows, open the file with Microsoft FrontPage if it is installed. A web browser may display the page if the file contains standard HTML, while a text or HTML editor can be used to inspect its source.
FrontPage-specific components may not work correctly outside FrontPage or on a server configured to support them.
There is usually no need for a separate conversion if the file already contains HTML. Open it in Microsoft FrontPage and save the page as standard HTML when that option is available.
Alternatively, edit the source and save a cleaned version with an .html or .htm file extension. FrontPage-specific components may need to be removed or replaced, and their functionality may not survive the conversion.
