What is an MHT file?

An MHT file is a webpage archive saved by a web browser, such as Google Chrome or Microsoft Edge. It is saved in the MIME HTML or "MHTML" format, which stores HTML, CSS, JavaScript, images, and other linked resources into a single file. MHT files are more commonly saved as .MHTML files.

MHTML stands for MIME encapsulation of aggregate HTML documents, or MIME HTML, which can be shortened as MHT. The format is useful for archiving online content on a local machine.

Follow these directions to create an MHTML web archive of a webpage in Chrome:

  • Windows - Select More tools → Save page as... in the menu and choose "Webpage, Single File"
  • macOS - Select File → Save Page As... and choose "Webpage, Single File"

NOTE: The content in the MHT file is encoded similarly to HTML email messages, allowing MHT files to be opened as .EML files by simply changing the file extension.

How do I open an MHT file?

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

You can also use applications besides web browsers to open MHT web archives. Examples include Microsoft Word and Kingsoft Writer.


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