Markdown to HTML Converter: Free Live Preview

This Markdown to HTML converter turns Markdown text into HTML code as you type, with a live preview next to the generated markup. Developers, bloggers and documentation writers can paste Markdown, check how it renders, and copy the HTML with one click. A second mode converts HTML back into Markdown.

What Is Markdown to HTML Conversion?

Markdown to HTML conversion is the process of reading plain-text Markdown syntax and writing the matching HTML elements. A line that starts with a pound sign becomes a heading, text wrapped in double asterisks becomes bold text, and a dash at the start of a line becomes a list item.

Markdown was designed to be easy to write and easy to read before it is ever rendered. Browsers, however, only understand HTML, so every Markdown document needs a conversion step before it can appear on a web page, in an email template or inside a CMS field that accepts HTML.

This converter handles the common Markdown features plus several GitHub-style extras. The built-in sample shows what it covers: headings, bold, italic, strikethrough, links, images, fenced code blocks, tables, task lists, blockquotes and horizontal rules.

How to Use the Markdown to HTML Converter

You can convert a document in under a minute, and nothing needs to be submitted because the output updates while you type. Follow these steps:

1. Make sure the Markdown → HTML button is selected. The input label reads Markdown Input.
2. Click the text box and type or paste your Markdown. If you only want to explore, click Load Sample to fill the box with an example document.
3. Open the Preview tab to see how the content will look when rendered, including headings, lists, tables and links.
4. Switch to the HTML Source tab to read the generated markup.
5. Click Copy HTML and paste the code into your page, template, CMS or email builder.
6. To go the other way, click HTML → Markdown. The label changes to HTML Input, and you can paste markup to get Markdown back.

Changing the mode re-runs the conversion on whatever is already in the box, so clear the box or load that mode's sample when you switch to avoid confusing output.

Worked Example: From Release Notes to HTML

A small example shows exactly what the converter produces and how to check it. Suppose you paste this Markdown, with a blank line between each block:

• # Release Notes
• Version **2.1** adds a [changelog](https://example.com/changes) page.
• - Dark mode
• - ~~Beta badge~~

The HTML Source tab then shows a first-level heading, a paragraph and an unordered list:

• <h1>Release Notes</h1>
• <p>Version <strong>2.1</strong> adds a <a href="https://example.com/changes">changelog</a> page.</p>
• <ul><li>Dark mode</li><li><del>Beta badge</del></li></ul>

In the Preview tab you would see a large heading, a sentence with bold 2.1 and a clickable link, and a bullet list where "Beta badge" is crossed out. If the preview matches what you intended, the markup is safe to copy. If the second bullet is not struck through, check that you used two tildes on each side of the text.

How Do You Read the Results?

The two tabs answer two different questions: the Preview tab shows what readers will see, and the HTML Source tab shows what your page will contain. Use both before you copy anything.

Preview tab

This is your quick visual check. Look for headings at the right level, lists that are actually lists, and tables with aligned columns. A common problem is a paragraph that looks like plain text when you expected a list, which almost always means a missing blank line or a missing space after the dash.

HTML Source tab

This tab is what you copy. Scan it for the elements you expect, such as heading tags, paragraph tags and code blocks. The table below shows how common Markdown features map to HTML.

Markdown vs HTML: What Is the Difference?

Markdown is a lightweight writing format, while HTML is the markup language browsers use to build pages. Markdown covers common text structures with short symbols. HTML can describe almost anything on a page, including forms, buttons, attributes, classes and layout.

People choose Markdown because it is faster to write, easier to review in version control, and harder to break with a missing closing tag. They choose HTML when they need control that Markdown cannot express, such as a custom class, an embedded widget or a specific attribute.

You can also mix them. The Markdown specification allows inline HTML inside a document, which is handy for the occasional element Markdown does not offer. Test any mixed content in the Preview tab, because how raw HTML is treated can differ between platforms.

Who Uses a Markdown to HTML Converter?

Anyone who writes in Markdown but publishes in a place that wants HTML will use this regularly. These are the most common situations:

• Bloggers and content writers who draft in a Markdown editor and need HTML for a CMS, newsletter or email platform.
• Developers who want to preview a README, changelog or documentation page before committing it. The sample covers GitHub-style features such as task lists and tables.
• Technical writers who convert a Markdown file into markup for a help center or knowledge base article.
• Teams migrating content from a static site into a CMS, or the other way around with the HTML to Markdown mode. For longer migrations, the dedicated HTML to Markdown converter is a good companion.
• Students and beginners learning Markdown, who can type a symbol and instantly see the HTML it creates.

If you work from an editor such as VS Code, you do not need an extension for a one-off job: copy the file contents, paste them into the input box and copy the HTML out. For automated builds that convert hundreds of files, a script in your own project is the better fit.

Best Practices and Troubleshooting Tips

Most surprising results come from small spacing mistakes in the Markdown, not from the conversion itself. These checks fix the majority of them.

• Leave blank lines between blocks. Put an empty line before and after headings, lists, tables, code fences and blockquotes.
• Add a space after list markers and heading symbols. A dash or pound sign with no space after it is treated as ordinary text.
• Close your code fences. If a fenced block is missing its closing backticks, everything after it may show up as code.
• Check your table separator row. A table needs a header row, then a row of dashes between pipes, then the data rows. Without the dash row, it renders as plain text.
• Indent nested lists consistently. Use two or four spaces for each level, and stick with one choice.
• Write the full link. Use square brackets for the label, then parentheses holding the full address, with no space between them.

After copying the HTML, run it through the HTML formatter if you want tidy indentation, or the HTML minifier when file size matters. To test the markup in a live page, paste it into an online HTML editor.

When you need a table in HTML directly

If you would rather build a table visually than type pipes and dashes, the HTML table generator produces the markup for you. If you only need the readable words from your HTML, the strip HTML tags page removes the markup and keeps the text.

Limitations to Keep in Mind

This tool converts content, not design. The HTML it produces contains your headings, paragraphs, lists, links and other structure, but no CSS, so it will take on the styles of whatever page you paste it into. Add your own stylesheet or classes if you need a specific look.

Markdown dialects differ slightly. A feature that works on one platform, such as footnotes or special alert boxes, may not be supported here, so always confirm the result in the Preview tab. In HTML → Markdown mode, complex markup with custom attributes, inline styles or layout elements has no Markdown equivalent, so review that output by hand before you publish it.

Finally, if you paste untrusted Markdown, read the HTML Source before placing it on a live site, especially when it contains raw HTML such as scripts or embedded frames.

With a live preview, a one-click copy button and a reverse mode, this converter takes you from Markdown draft to usable HTML quickly. Paste your text into the input box on this page, check both tabs, and copy the result.
