Where Markdown Is Used
- GitHub and GitLab — README files, pull request descriptions, issue comments, and wikis all render Markdown. The dialect used is GitHub Flavored Markdown (GFM).
- Documentation sites — MkDocs, Docusaurus, and Jekyll build documentation sites from Markdown files.
- Notion and Confluence — both support Markdown import and partial Markdown syntax in their editors.
- Chat apps — Slack, Discord, and Teams use Markdown-like formatting for bold, italic, and code blocks.
- Static site generators — Hugo, Gatsby, Eleventy, and Jekyll all use Markdown as their primary content format.
- Jupyter Notebooks — Markdown cells document code and analysis in data science notebooks.
- Email and writing tools — Bear, iA Writer, Typora, Obsidian, and many writing apps use Markdown as their native format.

Frequently Asked Questions
What is the difference between Markdown and HTML?▼
Markdown is a lightweight markup language designed for humans to write and read. It converts to HTML. HTML is the actual markup that browsers render. You write Markdown; a processor (like this tool) converts it to HTML. Most Markdown processors also allow raw HTML inline — so you can mix both.
Which Markdown flavor should I use?▼
If you are writing for GitHub (READMEs, issues, PRs), use GitHub Flavored Markdown (GFM). For general documentation or blog posts, CommonMark is a good baseline. For maximum portability between tools, stick to basic Markdown without extensions.
Can I include raw HTML in Markdown?▼
Yes. Most Markdown processors pass raw HTML through unchanged. You can embed
<div>, <span>, <table>, or any other HTML directly in your Markdown document. This tool renders inline HTML in the preview.How do I create a table in Markdown?▼
Use pipes and hyphens:
| Col1 | Col2 | on the first line, | --- | --- | on the second (the separator row), then data rows. Alignment: :--- left, ---: right, :---: center.Does Markdown support code syntax highlighting?▼
Yes, with fenced code blocks. Use triple backticks followed by the language name:
```python. The renderer applies syntax highlighting for the specified language. This tool supports highlighting for Python, JavaScript, SQL, Bash, JSON, and dozens more.How do I add a line break without starting a new paragraph?▼
End the line with two spaces before pressing Enter. Or use a
<br> tag. A single newline in Markdown is treated as a space, not a line break — two newlines create a new paragraph.
