| Description | MHT (MHTML) is intended for archiving web pages and combining the HTML code and resources - images, animation, audio files, into a single HTML file. These resources are usually represented as external links. The content of resulting files is encoded in the same way as in HTML email messages. MHT files use MIME type encoding. MHT files are directly supported by Internet Explorer and can be opened in it. Also, they can be opened in Firefox and other browsers, providing users install add-on software. |

An MHT file is a complete web page saved as a single archive — HTML, images, CSS, and all embedded resources packed into one .mht file. Internet Explorer created millions of them over two decades. The problem: IE is gone, and modern browsers do not open .mht files natively. Converting to PDF solves the compatibility problem permanently. The result opens on every device, in every browser, without any plugins or legacy software.
MHT (also written MHTML) stands for MIME HTML — a web archive format defined by RFC 2557. The format uses MIME multipart encoding to bundle the HTML source, inline images, stylesheets, scripts, and all other page resources into a single file. The .mht extension was the 3-character variant used by Internet Explorer 5 through IE 11, Windows Mail, and Outlook. Modern Chromium-based Edge and some Chrome versions use the .mhtml extension for the same format.

| Single-file archive | Yes — HTML + all resources in one file | Yes — self-contained document format |
| Live links | Preserved if browser supports it | Links work; page renders as fixed layout |
| Printable | Requires browser to render first | Directly printable from any PDF viewer |
| Long-term archival | Poor — depends on shrinking browser support | Excellent — PDF/A is the ISO archival standard |
