Markdown Editor

What is a Markdown Editor?

A Markdown Editor lets you write in Markdown, a plain-text format that uses simple symbols for headings, bold, links, and lists, and see the formatted result as you type. Markdown is widely used for README files, documentation, blog drafts, and notes because the source stays readable even without rendering. This editor shows the rendered HTML preview alongside your Markdown source.

How to Use This Tool

1. Type or paste Markdown into the editor pane.
2. Use # for a heading, **text** for bold, *text* for italic, and - item for a list item.
3. Check the preview pane to confirm headings, lists, and links render as expected.
4. Fix any line that did not render: most Markdown problems come from a missing blank line before a heading or list.
5. Copy the Markdown or the rendered HTML for use in your document, CMS, or README.

Worked Example

Input Markdown (3 lines):

# Project Notes

This release fixes **12 bugs** and adds 3 features.

Rendered HTML:

<h1>Project Notes</h1>
<p>This release fixes <strong>12 bugs</strong> and adds 3 features.</p>

The # produced one level-1 heading, the blank line separated the heading from the paragraph, and **12 bugs** became bold text. The numbers 12 and 3 are ordinary text in this example; Markdown does not calculate with them.

Limitations

• Markdown has no standard support for complex layouts, multi-column pages, or precise positioning. Use HTML or a page builder for those.
• Extended features such as tables, footnotes, and task lists depend on the Markdown flavour in use and may not render everywhere.
• The editor does not spell-check, grammar-check, or fact-check your writing.
• Embedded raw HTML may be stripped or ignored by some renderers for safety.
• Do not paste credentials or confidential text into any public web tool.

Frequently Asked Questions

Why did my heading not render?

Most often the heading line needs a blank line before it, or a space after the #. Write # Heading, not #Heading, and leave a blank line above the heading.

How do I add a link?

Use [link text](https://example.com). The text in brackets becomes the clickable label, and the URL in parentheses becomes the destination.

Can I convert Markdown to HTML here?

Yes. The preview shows the rendered result, and you can copy the rendered HTML for pasting into a CMS or web page. For a dedicated one-way conversion, use a Markdown to HTML converter.

Will my Markdown look the same everywhere?

Usually, for basic headings, bold, lists, and links. Tables, footnotes, and other extensions vary by renderer, so check the result in the place where it will be published.
