Markdown Preview - Live Editor & Viewer

Markdown preview with a live editor: type markdown, see rendered HTML instantly. Copy or download the result. Works offline.

Markdown Preview is a live markdown editor and viewer that runs entirely in your browser. Open the popup, type markdown on one side, and watch the markdown preview update on the other side with every keystroke. No account, no setup, no network connection — the markdown preview works offline and keeps your notes on your device. WHY THIS MARKDOWN PREVIEW ✏️ Live preview that updates as you type — no refresh button, no delay 🪟 Split view: markdown source next to the rendered result 📋 Copy HTML in one click and paste it into your blog, CMS or email 💾 Download .html to save the rendered document as a file 🗂 Autosave: your text is stored locally and restored when you return 🖥 Full-page markdown editor mode for longer documents 🔒 Private by design: the markdown preview never sends your text anywhere WHAT THE RENDERER SUPPORTS - Headings, bold, italic and inline code - Links and images - Bulleted and numbered lists, including nested lists - Tables with header rows - Fenced code blocks for snippets in any language - Blockquotes and horizontal rules - Clean, safe HTML output (script tags and javascript: links are neutralized) HOW TO USE THE MARKDOWN PREVIEW 1. Click the extension icon — the editor opens with a sample document. 2. Type or paste your markdown text in the left pane. 3. Watch the preview render headings, tables and code instantly. 4. Press "Copy HTML" to copy the markdown to html conversion result. 5. Or press "Download .html" to save the document, then open it in any browser. 6. Need more space? Press "Open full editor" for a full-tab markdown viewer. WHO IS IT FOR 1. Writers drafting README files and docs who want an instant markdown preview. 2. Developers checking how a .md file will render before committing it. 3. Students and note-takers who keep notes in markdown format. 4. Bloggers converting markdown to html for publishing. 5. Anyone learning markdown syntax with instant visual feedback. WHAT MAKES THIS MARKDOWN PREVIEW DIFFERENT The popup opens already rendered: a sample document shows headings, a table and a code block, so you can see the markdown preview in action before you type a single character. The split layout keeps the source and the result on screen together, which makes it easier to learn the syntax and to catch formatting mistakes early — the markdown preview doubles as a practice ground. FREQUENTLY ASKED QUESTIONS Q: Do I need an account? A: No. Install the extension, click the icon and the markdown preview is ready. Nothing to sign up for, nothing to configure. Q: Does this markdown preview work offline? A: Yes. The markdown editor, the renderer and the markdown to html export all run locally in your browser. No server is involved. Q: Where is my text stored? A: In your browser's local extension storage on your device. The markdown viewer never transmits or collects your content. Q: Can I preview an existing .md file? A: Yes — open the md file in any text editor, paste its content into the editor, and the markdown preview renders it immediately. Q: Does the live preview handle tables and code blocks? A: Yes. Tables, fenced code blocks, nested lists, blockquotes, links and images are all rendered in the markdown preview pane. Q: Is the exported HTML safe to publish? A: Yes. The renderer escapes raw HTML and removes javascript: links, so the markdown to html output stays clean. Q: How big can my document be? A: The markdown editor comfortably handles long documents; the live preview stays responsive while you type. A FOCUSED TOOL, NOT A SUITE This extension does one thing: markdown preview with a live editor. There is no toolbar clutter, no sign-in wall and no telemetry. Open the popup, write, see the result, copy or download it — done. If you write markdown every day or just need to check one snippet, this markdown viewer gives you the result in seconds. The markdown preview uses its own lightweight renderer, so the extension stays small and fast. Your markdown stays yours: everything happens on your machine, and the extension requests only the storage permission to save your draft between sessions. Install Markdown Preview and turn your browser into a quick markdown editor with an honest, instant live preview.
