Markdown Editor

How to use

1. 1Type or paste markdown in the editor on the left. The preview on the right updates as you type, with full support for headings, lists, tables, code blocks, links, images, and task lists.
2. 2Use the toolbar to insert headings, bold, italic, links, lists, blockquotes, code blocks, and a starter pipe table. Selected text is wrapped; an empty selection inserts a placeholder you can overwrite.
3. 3Switch between Split, Editor, and Preview using the layout buttons in the top right. Use the keyboard shortcuts Ctrl/Cmd+B, Ctrl/Cmd+I, and Ctrl/Cmd+K for bold, italic, and link.
4. 4Read the live word count, character count, line count, and estimated reading time below the panes. Use the table of contents to jump-check the structure of a long document.
5. 5Copy the markdown source, copy the rendered HTML body, copy a standalone HTML page, or click Download .md or Download .html. Set a title to control the file name.
6. 6Click any sample (README starter, Blog post draft, Meeting notes, Inline formatting) to load a working example, or open the cheatsheet for a quick syntax reference.

About this tool

Markdown Editor is a focused, browser-only writing surface for markdown with a live HTML preview that updates as you type. The editor and preview can sit side by side in split mode, or you can switch to editor-only or preview-only when you need more space. A formatting toolbar across the top inserts the most common markdown patterns (heading, bold, italic, strikethrough, inline code, link, bulleted list, numbered list, task list, blockquote, horizontal rule, fenced code block, and a sample pipe table) and wraps the current selection or inserts a sensible placeholder when nothing is selected. Keyboard shortcuts cover the writing essentials: Ctrl/Cmd+B for bold, Ctrl/Cmd+I for italic, and Ctrl/Cmd+K for a link, with Tab inserting two spaces so code samples and nested lists indent cleanly. The preview supports the GitHub-flavored markdown features writers actually use: ATX headings (# through ######), paragraphs with hard line breaks (two trailing spaces), bold and italic with both asterisk and underscore syntax, strikethrough, inline code spans, fenced code blocks with optional language hints, ordered and unordered lists with nesting, task list checkboxes (- [ ] and - [x]), blockquotes, horizontal rules, autolinks for both URLs and email addresses, inline links and images, and pipe tables with left, center, and right column alignment. Output is sanitized so pasted markdown cannot inject scripts or unsafe protocols. Live document stats below the panes show word count, character count, line count, and an estimated reading time at 225 words per minute. The table of contents panel auto-builds from your H1, H2, H3, and H4 headings so you can see the structure of a long document at a glance. When you are done writing, copy the markdown source, copy the rendered HTML body, copy a full standalone HTML page (with a small built-in stylesheet so it looks readable without any other CSS), or download a .md file or .html file directly. Built-in sample documents (a README starter, a blog post draft, meeting notes, and an inline-formatting reference) and a collapsible markdown cheatsheet make it easy to start without leaving the page. Useful for drafting README files for GitHub or GitLab, writing blog posts before pasting into a CMS, taking quick notes that you want to keep portable, sketching documentation, sharing meeting minutes, or just learning markdown by typing and seeing the result. Everything happens locally in your browser; the markdown you write here is never uploaded.
