MHTML (MIME HTML) is a web page archive format used to combine, in a single document, the HTML code and its associated resources such as images, audio, video, Flash animations, and other linked files. The content is encoded as if it were an HTML email message, using MIME (Multipurpose Internet Mail Extensions) to encapsulate the various resources. This allows a complete web page to be saved as a single file, making it easier to share and archive. MHTML files are often used for archiving web pages, sending complete web pages via email, and creating offline versions of web content. While convenient for archiving, MHTML files can sometimes be large due to the embedded resources. They are supported by most major web browsers, although some browsers may require extensions or plugins to fully support the format. The file extension for MHTML files is typically .mhtml or .mht.
