Markdown to HTML Converter

How Do You Convert Markdown to Clean HTML Without Installing Anything?

A free online Markdown to HTML converter turns lightweight Markdown text into HTML code and shows a rendered preview beside it. Type or paste your Markdown, press Convert, and copy the generated HTML from the code box. The conversion runs in your browser, so your text is never uploaded.

What does the Markdown to HTML Converter do and why is it useful?

Markdown is a plain text way of writing headings, lists, links and emphasis using simple symbols such as #, - and **. It is quick to write and easy to read, but web pages, email templates and content management systems often need real HTML. This tool bridges the two. You write in Markdown, and it produces the matching HTML tags.

The page opens with sample Markdown already in the textarea, so you can press the button immediately to see how the output looks and then replace the sample with your own text. Two results appear after each conversion: the HTML code, and a rendered preview that shows how the markup will look in a browser. Nothing updates while you type; the output changes only when you press the button.

How does the converter work under the hood?

The tool reads the text line by line and groups lines into blocks, then converts the formatting inside each block. All of it happens in JavaScript in your browser. Before any tags are produced, characters such as <, > and & in your text are escaped, so raw HTML typed into the box is shown as literal text rather than executed.

Supported syntax

You type	You get
# Title to ###### Title	Headings h1 to h6
**text**	Bold, using strong
*text*	Italic, using em
`code`	Inline code
Lines between triple backticks	A fenced code block
[label](https://example.com) or [label](/page/)	A link
- item or * item	Bullet list
1. item	Numbered list
> quote	Block quote
Consecutive lines of text	One paragraph, lines joined

Links are accepted only when the address begins with http, https or a slash for a path on the same site. A blank line ends a paragraph.

How do you use it step by step?

1. Look at the sample Markdown in the textarea, or select it and replace it with your own text.
2. Press the Convert button.
3. Read the HTML code in the code output and select the part you need.
4. Check the rendered preview to confirm headings, lists and links look right.
5. Edit the Markdown and press Convert again whenever you want fresh output.

What do real examples look like?

Each pair below was run through a converter that follows the rules above. Whitespace between tags is simplified here for readability.

Example 1: a heading

Input: ## Setup

Output: <h2>Setup</h2>

The number of hash marks sets the heading level, so # gives h1 and ###### gives h6.

Example 2: emphasis and inline code

Input: This is **bold**, *italic* and `code`.

Output: <p>This is <strong>bold</strong>, <em>italic</em> and <code>code</code>.</p>

Example 3: a bullet list

Input, three lines:

- milk
* eggs
- bread

Output:

<ul><li>milk</li><li>eggs</li><li>bread</li></ul>

A dash and an asterisk are both accepted as bullet markers, and consecutive bullet lines form one list.

Example 4: a numbered list and a link

Input: 1. Mix on one line and 2. Bake on the next gives <ol><li>Mix</li><li>Bake</li></ol>.

Input: Read the [free tools](/tools/) page.

Output: <p>Read the <a href="/tools/">free tools</a> page.</p>

Example 5: paragraph joining

Input, two consecutive lines: Read the guide. then It is short.

Output: one paragraph reading "Read the guide. It is short." The two lines are joined because there is no blank line between them. Insert a blank line to get two paragraphs.

Example 6: raw HTML is escaped

Input: Use <b>bold</b> & more typed literally into the box.

Output: the characters are escaped to entities, so the preview shows the tags as visible text instead of making anything bold. To escape or restore entities yourself, see the HTML Entity Encoder and Decoder.

Example 7: a small complete document

Input:

# Guide

Hello **world**.

- one
- two

Output:

<h1>Guide</h1>
<p>Hello <strong>world</strong>.</p>
<ul><li>one</li><li>two</li></ul>

Three blocks go in and three HTML elements come out. The preview shows a large heading, a sentence with one bold word and a two item bullet list.

Why write in Markdown instead of HTML?

HTML is precise but noisy. A single bold word needs an opening and a closing tag, and a list needs a wrapper plus one tag per item. Markdown keeps the text readable while you write, and it stays readable even if it is never converted. The trade-off is that Markdown covers only common formatting. Anything beyond headings, emphasis, links, lists, quotes and code needs real HTML, which is why this converter is best for straightforward articles, notes and documentation.

A practical workflow is to draft in Markdown, convert it here, and then paste the HTML into the place where it will be published. Because the output is plain HTML with no styling attached, your own site styles decide the final appearance of headings, lists and links.

What tips give the best results?

• Leave a blank line before and after lists, quotes and code blocks so each block is recognised cleanly.
• Use asterisks for emphasis. Underscores are not supported.
• Write one list level only. Nested lists are not supported, so split a complex outline into several lists or headings.
• Use full http or https addresses or paths that begin with a slash for links.
• Put code samples inside fenced blocks so symbols such as angle brackets are shown literally.
• Run the preview check before pasting the HTML into your page. It reveals a missing blank line quickly.
• Use the Word Counter to check the length of the text, and the Slug Generator to create a URL for the finished page.

What are common mistakes?

• Typing HTML inside the Markdown. Raw HTML is escaped, not passed through.
• Using underscores for emphasis. Only asterisks work.
• Indenting list items to nest them. Nested lists are not supported.
• Adding tables, images or horizontal rules. These are not converted and will not behave as they do in other Markdown tools.
• Forgetting the space after the marker. Write # Title and - item, with a space after the symbol.
• Waiting for live output. Results appear only after pressing Convert.

How should you check the output before publishing?

Start with the preview. Headings should look like headings, lists should show bullets or numbers, and links should be clickable. Then skim the HTML code for anything unexpected, such as a paragraph that swallowed a list because a blank line was missing. Fix the Markdown, press Convert again and compare. Repeating this loop a couple of times usually removes every formatting surprise before the text reaches a live page.

Who uses a Markdown to HTML converter?

• Bloggers and writers drafting in Markdown who need HTML for a publishing system.
• Developers turning README-style notes into snippets for a web page.
• Marketers preparing email or landing page copy from plain text notes.
• Students learning how Markdown symbols map to HTML tags.
• Support teams formatting help articles consistently.

Is it private?

Yes. Conversion runs entirely in your browser. The Markdown you type is not uploaded, stored or shared, and no account is needed. The tool keeps no history, so refreshing the page returns the textarea to the sample text.

What are the limitations?

• Not supported: tables, images, nested lists, horizontal rules, underscores for emphasis and raw HTML (it is escaped).
• Links must start with http, https or a slash.
• Output appears only after pressing the button, with no live preview.
• It is a compact converter, not a full implementation of every Markdown flavour, so unusual syntax may not behave as it does elsewhere.
• It does not sanitise or validate the finished page for you. Review the HTML before publishing.

Frequently asked questions

What is Markdown?

Markdown is a plain text format that uses symbols such as # and ** to mark headings and emphasis. It is easy to write and converts to HTML.

Can I use underscores for italic text?

No. Use single asterisks, for example *word*.

Does it support tables or images?

No. Tables and images are not supported.

Can I nest one list inside another?

No. Nested lists are not supported. Each list is a single level.

What happens if I type HTML tags?

They are escaped, so they show as visible text rather than working as markup.

Which links work?

Links whose address begins with http, https or a slash.

Why are my lines joined into one paragraph?

Consecutive lines belong to the same paragraph. Leave a blank line to start a new one.

Is my text uploaded?

No. Everything happens in your browser.
