# Welcome to Markdown Preview

Type on the left and watch the result render on the right — **instantly** and *privately*. Nothing you write here ever leaves your browser.
This second line shows how a single newline becomes a line break.

## Everything this preview supports

### Emphasis, code and links

Combine **bold**, *italic* and `inline code` freely, and add [links like this one](https://www.markdownguide.org) — they open in a new tab and only http/https URLs are allowed.

### Lists

- Unordered lists use `-`, `*` or `+`
- Indent two spaces to nest:
  - One level of nesting
  - Like these two items
- Back at the top level

1. Ordered lists use numbers
2. They stay in sequence
   1. And nest one level too
   2. With their own numbering

### Blockquotes

> Markdown lets you focus on the words. The formatting takes care of itself.
> Quotes can span multiple lines — and even contain **bold** text.

### Code blocks

```js
function greet(name) {
  return "Hello, " + name + "!";
}

console.log(greet("Hextrot"));
```

---

That `---` above renders a horizontal rule. One more thing: raw HTML is escaped, so pasting something like <script>alert("hi")</script> is always safe — it shows up as plain text.

A live Markdown editor and previewer

Markdown is the plain-text format behind GitHub READMEs, changelogs, documentation sites, help centers and most developer blogs: you mark up structure with a handful of punctuation characters, and tooling turns it into clean HTML. This editor renders your Markdown as you type — write on the left, see the finished document on the right. Everything happens in your browser: nothing is uploaded, and your draft is kept in local storage so a refresh never loses your work. When you are done, copy the generated HTML for your CMS or download the raw .md file for a repository.

The renderer supports the core syntax you use every day: three levels of headings, bold and italic emphasis, inline code and fenced code blocks, ordered and unordered lists with one level of nesting, blockquotes, links and horizontal rules. A single newline becomes a line break (like a GitHub comment) and a blank line starts a new paragraph. One deliberate safety choice: raw HTML in your source is escaped rather than rendered, so pasting untrusted text can never inject markup or scripts into the preview.

Markdown syntax cheatsheet

Forgot a marker mid-sentence? Every pattern below works in the editor above — try them straight from the table.

You type	You get
# H1 / ## H2 / ### H3	Headings, largest to smallest
bold and italic	Bold and italic emphasis
`code`	Inline code
``` … ```	Fenced code block (add a language after the opening fence)
- item / 1. item	Bulleted or numbered list — indent two spaces to nest
> quote	Blockquote
[title](https://url)	Link — opens in a new tab, http/https only
---	Horizontal rule
blank line	New paragraph (a single newline is a line break)

Frequently asked questions

Is my Markdown uploaded or stored on a server?

No. Parsing and rendering happen entirely in your browser, and your text never leaves your device. The draft is saved to your browser's local storage purely so a page refresh doesn't wipe it — the Clear button removes it completely.

Can I write raw HTML in my Markdown?

No — and that's deliberate. Every character of your input is HTML-escaped before rendering, so tags like <script> or <iframe> show up as plain text instead of executing. That makes the preview safe by default: you can paste Markdown from any untrusted source without worrying about hidden markup or scripts.

What does the Copy HTML button give me?

The rendered document as clean, semantic HTML — headings, paragraphs, lists, blockquotes, links and code blocks with no styling classes attached. It's ready to paste into a CMS, an email template or any page where you'll apply your own styles.

Which Markdown features are supported?

The everyday core: # through ### headings (deeper levels work too), **bold**, *italic*, `inline code`, fenced code blocks, ordered and unordered lists with one level of nesting, > blockquotes, [text](url) links (http and https only, opened in a new tab), --- horizontal rules, and GitHub-comment-style line breaks where a single newline becomes a break and a blank line starts a new paragraph. Tables, footnotes and images aren't supported.
