MHTML

MIME Encapsulation of Aggregate HTML

MHTML (MIME HTML) is a web page archive format that combines HTML, images, scripts, and other resources into a single file for easy storage and sharing. It is supported by web browsers like Microsoft Edge and Internet Explorer, as well as tools such as email clients and web development software. The format uses MIME encoding to embed external resources directly into the file, enabling self-contained web pages with advanced features like CSS, JavaScript, and multimedia elements.
