What is an MHT file?
MHT (MIME HTML) is a web archive format that adheres to the IETF standard RFC 2557. It combines HTML code and external resources-such as images, Flash animations, Java applets, and audio files-into a single file using MIME multipart/related encoding. This encapsulation allows entire webpages to be saved and transported as a singular static unit rather than an HTML file accompanied by a folder of assets.
How to open an MHT file
Microsoft Edge and legacy Internet Explorer provide native support for rendering MHT archives. While Google Chrome and Mozilla Firefox can process these files, they often require specific extensions or configuration flag adjustments to handle the MIME encapsulation correctly. Microsoft Word also supports parsing MHT files.
