Why convert Markdown to HTML?
You have content written in Markdown and need to display it in a browser or embed it in a web page. HTML is what browsers actually render.
What is a Markdown file?
Markdown: Markdown is a plain text format with simple formatting symbols. Headings use # signs, bold uses asterisks, links use brackets. Developers and writers use it because it's easy to read as raw text and converts cleanly to HTML.
Created by: John Gruber, first released in 2004
Used for: Documentation, README files, blog posts, notes, technical writing
Technical details: Plain text with lightweight formatting syntax. No binary data. Converts to HTML, PDF, and other formats. Many variations exist (CommonMark, GitHub Flavored Markdown).
Compatibility: Readable as plain text anywhere. Rendered by GitHub, VS Code, most note-taking apps, and static site generators.
What is a HTML file?
HyperText Markup Language: HTML is the language that web pages are written in. Every website you visit is HTML at its core. As a file format, .html files are plain text documents that browsers know how to render.
Created by: Tim Berners-Lee / W3C, first published in 1993

Technical details: Tag-based markup language. Supports text, images, links, tables, forms, and embedded media. Can include CSS for styling and JavaScript for interactivity.
