.MHTML File Extension

There is only one file type that uses the .MHTML extension:

MIME HTML File

MIME HTML File

An MHTML file is an archive that contains all the contents of a webpage. It stores the HTML of the webpage, as well as linked resources in the webpage, which may include CSS, JavaScript, images, and audio files. MHTML files are primarily used by web developers to save the current state of a webpage for archival purposes.

You can open MHTML files with various web browsers, including Google Chrome, Microsoft Edge, and Internet Explorer, whether you are online or offline. However, MHTML files saved in one web browser may appear differently when opened in another web browser because there is no standardized MHTML format utilized among all browsers.

You can also use applications other than web browsers to open MHTML web archives. Some examples include Microsoft Word, Kingsoft Writer, and WizBrother WizHtmlEditor.

Files with the .mhtml extension may be utilized by cybercriminals to distribute dangerous malware so you should verify the source you received the MHTML file from before opening it.
