Markdown vs HTML
Side-by-side comparison, when-to-use-each guide, and instant conversion. Reviewed for 2026.
Quick answer: Markdown is a lightweight syntax that converts to HTML. Use Markdown for content (blog posts, READMEs, documentation) and HTML for full control (custom layouts, semantic web, accessibility-critical pages). Markdown is far easier to write; HTML is far more powerful.

Use Markdown when…
GitHub READMEs, blog posts, technical documentation, note-taking apps, Slack/Discord formatting.
Use HTML when…
Full web pages, custom layouts, ARIA accessibility, anywhere you need fine-grained control of structure.

Frequently asked

Should I write my blog in Markdown or HTML?
Markdown, unless you need custom HTML elements regularly. The cleaner authoring experience compounds — Markdown content is far easier to migrate between platforms later.
