Convert xhtm to fpx

What is the difference between .xhtm and .fpx?

Description: The Extensible Hypertext Markup Language (XHTML) file type is an XML-based markup language for creating web pages. It is a hybrid of HTML and XML and is designed to replace HTML as the main language for creating web content. XHTML files provide a more flexible, extensible structure for web documents, allowing for more complex page designs and better integration with other web technologies.; The FPX (FlashPix Bitmap Image File) format is a type of image file designed to support high-resolution photographs and images. Developed in the mid-1990s by a consortium including Kodak, Microsoft, Hewlett-Packard, and Live Picture Inc., the FPX format is based on the Image Content Architecture (ICA), which allows it to store multiple resolutions of an image within a single file. This makes it especially useful for efficiently viewing and editing images without requiring the full image file.
