Markdown Pro

Render, edit & beautify Markdown in your browser. Scratchpad, split editor, syntax highlighting, themes & Mermaid.

Markdown Pro turns raw Markdown into beautiful, readable documents — instantly, and entirely on your own machine. Open a .md file or a raw Markdown page and Markdown Pro renders it automatically: clean typography, a floating table of contents, syntax-highlighted code blocks, GitHub-style tables, task lists, and nested blockquotes. No copy-pasting into an online viewer, no uploading your files anywhere. WHAT YOU CAN DO Auto-render Markdown — Open any .md or .markdown file (local files or raw GitHub/GitLab URLs) and see it beautifully rendered. A clean toolbar gives you a table of contents, dark/light themes, copy, print, and settings — right on the page. Scratchpad — Click the toolbar icon and paste Markdown from anywhere (notes, chat, a README) to preview it instantly. Your scratchpad content is remembered between sessions. Split editor — Write Markdown with a live side-by-side preview, a formatting toolbar, view modes, keyboard shortcuts, and a draggable divider. Download your work as a .md file anytime. Syntax highlighting — Code blocks are highlighted for dozens of languages, with a one-click copy button. Print to PDF — Print any rendered document to a clean PDF using your browser's built-in print dialog. Themes — Switch between polished dark and light themes, or follow your system setting. PRO FEATURES ($1.99/month) Copy as rich text (HTML clipboard) — paste formatted Markdown straight into email, docs, and more. Right-click "Preview as Markdown" — render any selected text on a page. HTML export — download a self-contained, styled .html file from the editor. Custom CSS themes — style your rendered documents exactly how you like. Mermaid diagrams — render flowcharts and diagrams from Markdown code blocks. PRIVACY FIRST Markdown Pro is fully offline after install. It does not track you, contains no analytics, and makes no external network calls — the only exception is connecting to extensionpay.com to manage Pro subscriptions if you choose to upgrade. Your documents never leave your computer. Built by Pharmetric.
