Markdown Previewer is a real-time editor that renders Markdown into formatted HTML as you type. It supports GitHub Flavored Markdown including fenced code blocks with syntax hints, pipe tables, task checkboxes, strikethrough, blockquotes, and nested lists — with a formatting toolbar so you never have to memorise syntax.
Yes. The preview pane re-renders on every keystroke with a short debounce to avoid unnecessary redraws. You see the formatted output the moment you stop typing, with no button needed.
The previewer supports the full CommonMark spec plus GitHub Flavored Markdown extensions: pipe tables, fenced code blocks with optional language identifiers, task list checkboxes, strikethrough with ~~text~~, and automatic URL linking.
Your Markdown is automatically saved to your browser's local storage so it survives page refreshes. Use the Export HTML button to download a standalone HTML file, or Copy HTML to paste the rendered output elsewhere.
Export creates a complete standalone HTML file that includes the rendered content wrapped in a minimal HTML document with basic typography styles. You can open it in any browser or drop it into a project without any additional dependencies.
Each button in the formatting toolbar inserts the relevant Markdown syntax at the current cursor position. If text is selected, wrapping syntax such as Bold or Italic wraps the selection. If nothing is selected, a placeholder is inserted.
Yes. Press Ctrl+B (or Cmd+B on Mac) for bold and Ctrl+I (or Cmd+I) for italic while the editor is focused. The shortcut wraps selected text or inserts placeholder syntax at the cursor.
Markdown has become the default writing format for developers, technical writers, and documentation teams around the world. It is easy to read in its raw form, easy to version-control with Git, and renders beautifully in GitHub, GitLab, Notion, VS Code, and countless other tools. The challenge is that you often cannot see what the formatted output looks like until you push a commit or switch to a preview mode. This Markdown Previewer solves that problem by rendering your Markdown into formatted HTML the instant you type — no builds, no page reloads, no browser extensions required.
The editor uses a split-pane layout with the raw Markdown source on the left and the rendered HTML preview on the right. Both panes scroll independently so you can keep the beginning of your document in view on the left while scrolling through the formatted output on the right. If you want to focus entirely on writing or entirely on reading, use the view mode toggle to switch to Editor Only or Preview Only mode. The pane divider is draggable so you can give more space to whichever side you need.
Standard Markdown covers the basics — headings, bold, italic, links, images, lists, blockquotes, and code spans — but modern documentation commonly relies on GitHub Flavored Markdown (GFM) extensions. This previewer supports fenced code blocks with optional language identifiers for downstream syntax highlighting, pipe tables with alignment hints, task list checkboxes that render as checked or unchecked, strikethrough text, and automatic hyperlinking of bare URLs.
Not everyone has Markdown syntax memorised, especially for less common elements like tables or task lists. The formatting toolbar at the top of the editor inserts the correct syntax at the cursor with a single click. Select a word and click Bold to wrap it in double asterisks. Click Table to insert a ready-made three-column pipe table template you can edit immediately. Click Code Block to open a fenced code block with the cursor positioned inside. Every button works with and without a selection.
When your document is ready, you have two options for extracting the rendered output. Copy HTML copies the inner HTML of the preview pane to your clipboard so you can paste it directly into a CMS, email template, or another editor. Export HTML downloads a complete standalone HTML file that includes a minimal CSS reset and typography styles so the output looks polished when opened in a browser or shared with a colleague who does not have a Markdown viewer.
The toolbar shows a live word and line count so you can track document length without switching tools. This is particularly useful when writing documentation with length guidelines, blog posts targeting a specific word count, or README files where brevity is important.
