The PPTX file format is a proprietary XML based file format developed by Microsoft. It is mostly associated with Microsoft office PowerPoint, a closed source slide show presentation application. It is the default format that succeeded the .ppt filename extension from Microsoft PowerPoint 2007 SP1 onwards and is part of the Office Open XML specification. Documents to be saved in the .pptx format are saved as PowerPoint presentations. Because the pptx file format is part of the larger opendocument XML file format, many non-proprietary applications are able to open files saved with the .pptx filename extension.
The hypertext markup language, commonly referred to as HTML is at the backbone of the internet and World Wide Web. It is the standard markup language used in the creation of webpages and was released in 1993 at the advent of the internet. The format defines the structure and layout of a webpage through markup tags such as header tags and image tags from which a browser can interpret multimedia information for on screen presentation. To view files and webpages saved with the .html filename extension, one needs a compatible web browser that implements the HTML specification. Because the format is open source, several browsers which are mostly free to use can open such files. The World Wide Web consortium actively maintains and updates the html specification.

The .pptx filename extension is a compressed ZIP archive with an xml directory structure. The format supports macros, charts, embedded media files, and images. It is specified in the open standard ISO/IEC 29500-1:2012. A free compatibility update allows older versions of Microsoft Office PowerPoint such as Office 2003 to open .pptx documents.
The internals of an html file are a structure of nested html elements represented as language specific tags enclosed in angle brackets for example '<title>'. There are several of these tags each with their own representative meaning in the html markup language. The html specification relies on the hypertext transfer protocol to distribute .html files over a network such as the internet. However, .html files can also be distributed as embedded content within an email.
