How does Markdown become HTML?

Markdown patterns such as # headings, **bold**, lists, links, and code blocks are parsed and converted into semantic HTML elements.

Can I preview Markdown as HTML?

Yes. This page shows generated HTML and a rendered preview so you can review the result before copying it.

Does this support Markdown tables?

Yes. This local parser supports simple pipe-style Markdown tables with a header row, separator row, and body rows.

Does this support code blocks?

Yes. Fenced code blocks are converted to pre and code elements with escaped content.

Is raw HTML inside Markdown safe?

Raw HTML can be risky if it comes from an unknown source. This tool disables raw HTML by default and can sanitize unsafe patterns.

What does sanitizing HTML mean?

Sanitizing removes or blocks unsafe HTML patterns such as scripts, event handlers, and javascript links.

Can I copy the generated HTML?

Yes. Use the copy HTML button to copy the generated output.

Does this tool upload my Markdown?

No. Conversion runs locally in your browser without backend calls.

Can I use this for blogs or documentation?

Yes. It is useful for blogs, documentation, CMS content, README previews, static sites, and developer notes.

How Markdown to HTML Conversion Works

Markdown is a lightweight writing format for readable plain text.

HTML is the markup language browsers render.

Markdown syntax maps to HTML tags such as h1, p, ul, ol, a, code, and blockquote.

Code blocks become pre and code elements with escaped content.

The preview renders generated HTML after applying selected raw HTML and sanitization settings.

Safety, Sanitization, and Raw HTML Notes

Markdown conversion is safest when input is treated as text.

Raw HTML inside Markdown can include risky patterns.

Sanitization removes scripts, event handlers, and unsafe javascript links.

The preview should not be used to trust unknown HTML without review.

Links and images should be checked before publishing.

CMS platforms may apply their own HTML sanitization rules.

Common Markdown-to-HTML Examples

Heading to h1

# Hello → <h1>Hello</h1>

Paragraph to p

Text → <p>Text</p>

Bold to strong

**Bold** → <strong>Bold</strong>

Italic to em

*Italic* → <em>Italic</em>

Link to anchor

[Site](url) → <a href='url'>Site</a>

List to ul/li

- Item → <ul><li>Item</li></ul>

Code block

```js → <pre><code>

Blockquote

> Quote → <blockquote>Quote</blockquote>
