About the formats

What is PPTX?

PPTX (PowerPoint Open XML) is the standard format for slide-based presentations, created and edited in Microsoft PowerPoint, Google Slides and LibreOffice Impress. A presentation is made up of slides that can hold text, images, charts, videos and speaker notes. Like other modern Office formats, PPTX files are ZIP containers storing XML.

Use PPTX whenever you build a slide deck to present, pitches, lessons, webinars and team updates. It keeps the structure of slides and notes intact, so you can also convert it to PDF to share a fixed version.

What is HTML?

HTML (HyperText Markup Language) is the markup language used to structure web pages, defining headings, paragraphs, links, images and more. Every website you visit is built on HTML. It is plain text that a browser interprets and renders into the page you see.

Use HTML whenever you publish content on the web, pages, articles, emails or anything meant to be read in a browser. It is also the destination format when converting a text document into a web page.
