How to preview Markdown
- Type or paste Markdown into the left pane — the preview updates live as you type.
- Use the usual syntax:
#headings,**bold**,*italic*,-lists,`code`,>quotes, and[text](url)links. - Click Copy HTML to grab the rendered markup for a website, email or CMS.
What Markdown is for
Markdown lets you write formatted text with plain punctuation instead of clicking toolbar buttons, which is why it's everywhere developers and writers work: README files, GitHub issues and pull requests, static-site posts, documentation, Reddit and Discord messages, and note apps like Obsidian and Notion. This previewer renders the common CommonMark and GitHub-flavored basics — headings, emphasis, lists, links, images, code blocks, blockquotes and rules — so you can check formatting before you publish. For safety it escapes any raw HTML in your input rather than running it, and because everything happens on your device, it's fine for drafts and private notes you'd never paste into an online editor.
Frequently asked questions
What Markdown syntax is supported?
Headings, bold and italic, inline code and fenced code blocks, ordered and unordered lists, links and images, blockquotes, horizontal rules and strikethrough.
Can I copy the generated HTML?
Yes — click Copy HTML to get the rendered markup, ready to paste into a website, email template or CMS.
Is it safe to paste sensitive or draft content?
Yes. Rendering happens entirely in your browser — nothing is uploaded or stored, and any raw HTML is escaped rather than executed.
Does it work offline?
Yes — once the page loads you can disconnect and the preview keeps working, because all rendering runs locally.
