Markdown Preview
Write Markdown and see the formatted HTML render live, side by side.
Preview Markdown as you type
The Markdown Preview tool renders your Markdown into formatted HTML live, side by side, so you can see exactly how it will look. It supports the everyday Markdown you actually use — headings, bold and italic, links, inline code, code blocks, and bulleted lists. Everything runs in your browser, instantly and privately.
What is Markdown?
Markdown is a lightweight markup language that lets you format text using simple, readable symbols — # for headings, ** for bold, - for list items. It's the standard for README files, documentation, GitHub, chat apps, static sites, and note-taking tools because it stays readable as plain text while converting cleanly to HTML.
Quick syntax reference
| Markdown | Result |
|---|---|
| # Heading | A heading (use 1–6 #) |
| **bold** | bold text |
| *italic* | italic text |
| [text](url) | a link |
| `code` | inline code |
| - item | a bullet list |
How to use it
- Type or paste Markdown in the left pane.
- Watch the formatted preview update on the right.
- Refine your formatting until it looks right.
Why preview matters
Markdown's whole appeal is that it's readable as plain text, but small mistakes — a missing blank line before a list, an unclosed code fence, or a stray asterisk — can produce unexpected output. A live preview catches these instantly, so you ship clean READMEs, docs, and posts without committing and re-checking on the destination platform.
Where Markdown is used
- GitHub & GitLab — READMEs, issues, and pull requests.
- Documentation — static site generators and wikis.
- Notes — apps like Obsidian and Notion.
- Chat — Discord, Slack, and forums.
Private and free
Rendering happens entirely in your browser — your content is never uploaded. The tool is completely free with no sign-up.
