What is a .mht file?

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 media. The content is encoded as MIME data, similar to email attachments. MHTML files are often used to save complete web pages for offline viewing or archiving. This format ensures that all elements of the web page are preserved within a single file, eliminating the need to manage multiple linked files. It's particularly useful for sharing web content without relying on a live internet connection or worrying about broken links. While widely supported by older versions of Internet Explorer, support in other browsers has varied. Modern browsers often offer alternative methods for saving web pages, such as saving as a single HTML file or creating a folder containing the HTML and associated resources. However, MHTML remains a viable option for archiving web content, especially when compatibility with older systems is a concern.
