The MHT format is an alternative name and suffix for the MHTML documents (MIME HTML) which is an archive format for the web pages saved with internet explorer by default. The format can contain multiple resources like flash, java, images, audio etc. and external links all together with html code. The file is then encoded using the MIME type multipart. The MHTML format is however not standardized as many applications display and save the file differently. Also most of the web browsers have gave up in supporting the file and at this point only Internet Explorer and Firefox can still open and save it with or without additional addons installed.
Due to this situation, a format like the PDF one is welcome for anyone needing to further work with the mht files. The PDF documents can be opened, shared and enhanced easier and with the help of a PDF converter such as novaPDF additional actions can be performed on the file such as signatures, security setup, setting up logos on the file for copyrights with watermarking, bookmarking etc.
