PPTX

PowerPoint Open XML Presentation

PPTX is a file format used for creating and sharing presentations, developed by Microsoft as part of the Office Open XML specification. It is primarily used in Microsoft PowerPoint but is also supported by other presentation software like LibreOffice, Google Slides, and Apple Keynote. The format stores data in a compressed ZIP archive containing XML files for slides, media, and metadata, enabling advanced features like animations, transitions, and embedded multimedia.

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.
