What it does
Markdown Preview is a live Markdown editor. Type on the left and see the rendered result on the right as you write: headings, lists, links, images, tables, code blocks and quotes. It is handy for drafting a README, release notes, a blog post or documentation before you commit it, and for checking how a tricky table or nested list will look.
Switch the view to HTML to see the generated markup, then copy it or download a complete HTML page with basic styling.
How to use
- Type or paste Markdown into the input, drop a
.mdfile on it, or click Sample. - The preview updates as you type. The line above it shows the word, heading and link counts.
- Choose Preview to see the rendered page, or HTML to see the markup.
- Use Copy HTML to paste the result into a CMS or an email, or Download HTML for a standalone file.
Markdown cheat sheet
| You type | You get |
|---|---|
# Title | A level-1 heading (## for level 2, up to ######) |
**bold** and _italic_ | bold and italic |
[text](https://example.com) | A link |
 | An image |
- item or 1. item | Bulleted or numbered lists |
- [ ] todo | A task list checkbox (GFM) |
`code` | Inline code |
```js on its own line | A fenced code block with a language |
> quote | A block quote |
--- | A horizontal rule |
Tables use pipes and a separator row: | a | b | followed by | --- | --- |. Tables are a GitHub Flavored Markdown extension, not part of CommonMark, so they only render while GitHub Flavored Markdown is on; with it off they show as plain text with pipes.
Example
## Highlights
- [x] Tables and task lists
- ~~Old API~~ removedrenders as a second-level heading followed by a checked task item and a struck-through line.
FAQ
› Which Markdown syntax is supported?
CommonMark plus GitHub Flavored Markdown: tables, task lists, strikethrough, fenced code blocks and automatic links. Turn GFM off to see how a strict CommonMark renderer would display your text.
› Is it safe to paste Markdown that contains HTML?
Yes. Markdown allows raw HTML, so the preview is shown in a sandboxed frame where scripts cannot run. The HTML you copy is not sanitized, so clean it before publishing untrusted content on your own site.
› Why does a single line break not start a new line?
In standard Markdown, a single newline is treated as a space, and a blank line starts a new paragraph. Turn on "Line breaks become <br>" to render every newline as a line break, as GitHub does in comments.
› Is my text saved?
Your last input is kept in this browser's local storage so it survives a reload. It is never uploaded; you can clear it with the Clear button.
