CHM

Microsoft Compiled HTML

The CHM file format was developed by Microsoft for storing and displaying online help documentation, combining multiple HTML pages into a single compressed file. It is commonly opened using Microsoft's HTML Help Viewer, but third-party tools like 7-Zip or SumatraPDF can also extract or view CHM files. The format supports a hierarchical table of contents, full-text search, and embedded multimedia, making it a versatile solution for organizing and accessing help content efficiently.

MHT

MIME Encapsulation of Aggregate HTML

MHT is a file format used to save web pages as a single file, combining HTML, images, CSS, and other resources into one archive for easy storage and sharing. It is supported by web browsers like Internet Explorer and Microsoft Edge, as well as tools like Microsoft Word and specialized MHT viewers or converters. The format uses a MIME structure to embed all web page elements, including text and binary data, into a single file, often encoded in Base64, enabling offline access and preservation of web content.
