Markdown Editor Free — Markdown to HTML/PDF

Markdown is the fastest way to write a formatted document: a hash for a heading, two stars for bold, a dash for a list item, and you have a clean page without ever touching a word processor. This free Markdown editor turns what you type into a live HTML preview as you write, and it works both ways — paste HTML in and get Markdown back. There is no account, no sign-up and nothing to install. Your text never leaves your browser: the conversion runs on your device using small libraries loaded from this site, so drafts, notes and README files stay private. When the preview looks right, download the finished page as an HTML file, copy the HTML for your website, or print it straight to PDF from your browser.

How to Use

1. Write Markdown in the top box. Use # for headings, **text** for bold, *text* for italic, - for list items, [text](https://example.com) for links and `code` for inline code. The preview below updates as you type.
2. Check the live preview. The preview shows exactly how your document will look as HTML. Fix any formatting that looks wrong in the Markdown box, not in the preview.
3. Download, copy or print. Click Download HTML to save a ready-to-use .html file, Copy HTML to paste the code into your website, or Print / Save as PDF to save a PDF through your browser's print dialogue.
4. Convert HTML back to Markdown. Paste HTML into the lower box and click Convert HTML to Markdown. Headings, bold, italic, links, lists and code blocks come back as Markdown, ready to paste into a README or note.

Worked Example

Type this short document into the Markdown box:

# Hello

This is **bold**.

The first line starts with a single hash, so it becomes a top-level heading. The blank line separates it from the paragraph, and the two stars around “bold” mark that word as strong. The HTML the editor produces is exactly:

<h1>Hello</h1><p>This is <strong>bold</strong>.</p>

You can confirm this by clicking Copy HTML after typing the example and pasting it into any text editor. Try the reverse direction too: paste that HTML into the HTML to Markdown box and click Convert HTML to Markdown, and you will get the original Markdown back — # Hello on the first line and This is **bold**. as the paragraph. The sample document, loaded with the Load Sample button, shows two heading levels, a list, a link and a code block in one go.

Why Write in Markdown?

Markdown keeps your words readable even before they are converted. A Word document is a closed file you can only open in the right program; a Markdown file is plain text you can open anywhere, search, email, store in version control and edit on any device, and it will still be readable in twenty years. That is why README files, documentation, blogs and notes are written in Markdown. It also stops formatting from getting in the way of writing: there are no fonts, margins or ribbons to fiddle with, only a handful of marks you can learn in ten minutes. Markdown has no page-layout controls — no columns or precise image placement — so it is the wrong choice for a designed brochure. For articles, notes, guides and web pages, it is the fastest honest format there is.

Tips for Clean Markdown

Always leave a blank line before and after a heading, a list or a code block, because most converters need the empty line to recognise where one block ends and the next begins. Use one hash for the page title and two hashes for sections, and never skip from # straight to ###, since screen readers and search engines read the heading order as the document outline. For links, write descriptive text — [Markdown guide](https://example.com) — instead of pasting a bare address, which is harder to read and uglier in print. Keep lines short, around 80 characters, so the raw text is easy to scan in any editor. Finally, preview before you publish: a missing blank line or an unclosed pair of stars is the cause of almost every “my formatting broke” surprise, and this page shows it the moment you type it.
