What Is the File Extension .MHTML?

Hypertext Markup Language (HTML) is a programming language used to create the layout for Web pages. A number of different files are associated with HTML programming, including those that use the .MHTML file extension.

Identification

A file with the .MHTML file extension is known as a Mime HTML file, an archiving format.

Function

A file with the .MHTML file extension contains a copy of a Web page saved to your computer that you can access even when you are not online.

Features

An .MHTML file contains not only the text from the website, but any other elements found on the Web page as well, such as animations, images, movies or audio files.

Browsers

A number of browsers on Mac OS X and Windows computers have the ability to create and open .MHTML files, including versions 5 and later of Microsoft Internet Explorer, Mozilla Firefox (with the Mozilla Archive Format extension installed) and Opera.

Considerations

An .MHTML file contains only one page from a website, so none of the links on the website will work if you are offline. In order to access a number of different pages within a website while offline, it is necessary to save each page as a separate .MHTML file.
