What is an MHT file?
An MHT file is a webpage archive saved by a web browser, such as Google Chrome or Internet Explorer. It is formatted using MIME HTML or "MHTML," which saves HTML, images and other linked resources into a single file. MHT files are more commonly saved as .MHTML files.
Most webpages viewed in a web browser only contain HTML and reference images and other media files that are stored in other directories on the server. Because all the files are encoded with .MIME encoding into a single file in an MHTML document, MHT files are commonly used to archive webpages.
NOTE: Microsoft Word can save and open MHTML Web archives.
