Markdown is a lightweight markup language that uses plain text formatting syntax. You write # for headings, ** for bold, * for italic, and - for lists. It converts to HTML for display on websites and documentation.

Can I export my Markdown?

Yes. Click '.md' to download your Markdown as a .md file. Click 'Copy HTML' to copy the rendered HTML output that you can paste directly into a webpage or CMS.

What Markdown syntax is supported?

Headings (H1—H6), bold, italic, bold+italic, strikethrough, inline code, links, images, blockquotes, unordered lists, ordered lists, and horizontal rules.

Is my text saved anywhere?

No. Everything runs in your browser. Your text is never sent to any server. Refreshing the page will clear the editor.

Can I use this for GitHub READMEs?

Yes. The editor renders GitHub Flavored Markdown (GFM), including tables and fenced code blocks with syntax highlighting. The preview closely matches how GitHub renders README.md files.

Content is not automatically saved to any server. Use the Download .md button to save your work locally. The editor may retain content in browser localStorage during the session.
