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 Markdown?

Markdown is a lightweight markup language that lets you write formatted documents in plain text using simple symbols. The same file reads clearly as text and renders as styled HTML, making it popular for documentation, README files and notes. It is also widely used to feed clean text to large language models.

Use Markdown for content that should be readable as plain text but publishable with formatting, README files, documentation, wikis, notes and posts. Write it anywhere, and it stays usable forever because the source is plain text.
