Render & edit Markdown: Mermaid diagrams, math, code highlighting, tables, outline, highlights, annotations, PDF/PNG/HTML export. Markdown Pro Max is a capable, polished Markdown viewer and editor for Chrome: open a `.md` file and it renders instantly, with source editing, Mermaid diagrams, math formulas, tables, outline navigation, highlighting & annotation, and multi-format export. **How to Use:** - For local files, first enable "Allow access to file URLs" on the extension's details page (`chrome://extensions`); otherwise `.md` files won't render. - Just drag a `.md` / `.markdown` file into the browser window to open and render it — or open a local / online Markdown file from the browser. ## Feature List - Markdown rendering - Mermaid diagrams - Code syntax highlighting - Math formulas (KaTeX) - Image attribute syntax `{width=... height=...}` - Image click-to-zoom / gallery browse (prev/next through all images) - Table copy (Markdown / Excel / HTML) - Table column sorting - Theme switching (Light, Dark, Eye-comfort) - Mermaid theme - Adjustable page width (60%–100%) - Page border & shadow - Reading progress bar - Reading completion confetti - Word count - Outline sidebar - [TOC] inline table of contents marker (auto-generate TOC from headings) - task lists (`- [ ]` / `- [x]` checkboxes) - Open links in new tab (configurable) - File annotations (pen, line, rectangle, circle, text, highlighter) - Source editing (edit / save to original file / save as / Markdown syntax help) - Export to PDF / PNG / HTML - Auto-refresh (auto-reload on file changes) - Local file support
