Markdown is a plain-text way to write formatted documents, using simple marks for headings, bold, lists, links and code. It is popular for notes, documentation, and blog drafts, because it is quicker to type than full HTML and easier to read than raw HTML. A live preview is useful because it shows immediately whether a heading, list, or link has been written correctly, without needing to publish anything.
Check the preview before you copy the HTML, especially for lists and links, because a missing blank line or a misplaced bracket can change how they render. Markdown is forgiving in some places and strict in others, so the preview is the quickest way to catch those mistakes.
Privacy: this tool runs entirely in your browser — no upload, no signup, and your files never leave your device.
Write Markdown and watch how it will look as you type — headings, bold, lists, quotes, code, everything. A live preview builds up beside it.

Frequently asked questions
What is Markdown?
Markdown is a plain-text format for writing formatted documents. You use simple marks, such as # for a heading, ** for bold, and - for a list item, and a previewer turns those marks into formatted text. It is widely used for notes, documentation and blog drafts.
Can I copy the preview as HTML?
Yes. The tool can copy the HTML version of your preview, which you can paste into a website editor or a document that accepts HTML. The Markdown itself stays as plain text, so you can keep editing it afterwards.
Why does my list not render correctly?
Lists in Markdown usually need a blank line before them and a space after the dash or number. If a list renders as plain text, check for those two things first, because they are the most common causes.
Is my Markdown uploaded when I preview it?
No. Previewing happens in your browser only. Nothing is sent to a server and nothing is saved after you close the page.
