What is a MHT file
MHT files are associated with MHTML (Mime HTML) archive formats. This file type is used when saving a web page as a web archive on the Internet Explorer browser. Mozilla Firefox and Safari lack direct support of these files, but third-party add-ons can allow users to utilize MHT files. Google Chrome allows the creation of MHT or MHTML files by providing the option to “Save Page as MHTML” to the “chrome://flags” page. Internet Explorer can create these files without the assistance of applications or plug-ins. These archives are useful because multiple elements of a webpage are saved into a single file for easier viewing and access.
Information about the website is remapped and the content is embedded within the MHT file, much like an HTML e-mail. When created with Microsoft Word, Internet Explorer, or Opera, these files are created with a MHT extension. Other programs may use the name MHTML instead. MHT has been a proposed standard since 1999 as RFC 2557. For MHT files, the HTML is usually encoded and the rest is identified by their original URL’s and encoded in base64. Some commercial products allow for the viewing and converting of MHT files into formats like PDF which makes it easy to send and print the contents of the file.
Here's a small, but not exhaustive list of programs that can open MHT documents:
- Mozilla Firefox
- Google Chrome
- Microsoft Internet Explorer
