What Markdown is, how to use the preview, privacy, GitHub-Flavored Markdown, HTML export and mobile support.
What is Markdown and what does this tool do?
Markdown is a simple way to format plain text using punctuation: a # makes a heading, **stars** make text bold, a dash starts a list. This tool is a live Markdown editor — type Markdown on one side and it instantly renders the formatted result on the other, so you can see exactly how your README, comment, note or documentation will look before you publish it.
How do I use the Markdown preview?
Just start typing in the editor — the preview updates with every keystroke. Use the toolbar buttons (H1, Bold, Link, Table…) to insert formatting without memorising the syntax, switch between Split, Editor and Preview views on desktop, or tap Write / Preview on mobile. When you're happy, copy the Markdown or HTML, or download a .md or .html file.
Is my text private? Is anything uploaded?
Everything runs entirely in your browser. Your Markdown is never sent to a server — there's nothing to upload and nothing is stored online. Your draft is auto-saved to this browser's local storage so it survives a refresh, and you can wipe it any time with the Clear button.
Does it support GitHub-Flavored Markdown (GFM)?
Yes. On top of standard Markdown it supports the GitHub extensions people use most: pipe tables, task lists with checkboxes (- [x]), strikethrough with ~~tildes~~, fenced code blocks, and autolinking. That makes it a great way to preview a GitHub README, issue or pull-request comment before posting it.
Will the preview match GitHub or my site exactly?
The structure (headings, lists, tables, code, links, images) will match, because that's defined by the Markdown spec. The exact fonts, colours and spacing are styled by whatever site finally displays it, so visuals can differ slightly. For most READMEs and docs the rendered result here is faithful enough to catch every formatting mistake.
Can I export the result as HTML?
Yes. Use Copy HTML to grab the rendered markup, Copy rich text to paste formatted text straight into Word, Google Docs or email, or Download .html for a complete, styled web page you can open in any browser. You can also Download .md to save the raw Markdown source.
What do the stats and charts show?
As you write, the tool counts your words, characters, lines and estimated reading time, then breaks down every element — headings, links, images, code blocks, lists, tables and more — into cards and charts. There's a heading-level chart to check your document hierarchy and a task-list progress bar, so you get a quick health-check of your content's structure.
Does it work on my phone?
Yes — it's fully responsive down to very small screens (around 280px wide). On mobile the editor and preview become Write / Preview tabs so the rendered output sits right next to the input with a single tap, and detailed stats are shown as cards instead of wide tables you'd have to scroll sideways.
Is it safe to paste Markdown that contains HTML?
Markdown lets you mix in raw HTML, and this tool renders it so the preview is accurate. For safety it strips anything that could run code — script tags, event handlers and javascript: links — before showing the preview, so even a copied snippet can't do anything harmful in your browser.
Do I need to create an account?
No. There's no sign-up, no login and no limits. Open the page and start writing — the tool is completely free.
