Markdown Viewer

View and browse Markdown documents from local folders with a rich sidebar, history, and table of contents.

The best way to read, organize, view, and export documents in Chrome. Markdown Viewer Pro opens a local document workspace for Markdown and common document formats. Browse folders, create and edit Markdown files, search filenames and file contents, ignore unwanted paths, pin favorites, view recent documents, switch themes, and export supported files. Your documents stay on your device; optional Pro billing uses hosted checkout and license verification. ✨ Key Features: • 📁 Folder Browser — Open a local folder and browse supported documents • ➕ Create Markdown Files — Add a new file to a root folder or any visible subfolder • ✍️ Built-In Editing — New files open automatically in split editor and preview mode • 📄 Multi-Format Viewing — View Markdown, text, HTML, Word, PDF, RTF, OpenDocument, and EPUB • 📝 Markdown Rendering — GitHub-flavored markdown with tables, task lists, and blockquotes • 🎨 Code Highlighting — Automatic language detection for code blocks • 📐 Mermaid & Math Support — Render diagrams and LaTeX equations • 📑 Table of Contents — Navigate long documents easily • 🌙 Themes — Switch between dark and light mode • ⭐ Favorites & History — Quickly reopen important or recent files • 🔍 Filename & Content Search — Use one search field to filter filenames while searching inside Markdown, text, and HTML files • 📃 Search Results — Review matching files, root-qualified paths, and one-line content previews in the main workspace • 🚫 Ignore Rules — Exclude files or folders with gitignore-style patterns, negation rules, or regular expressions • 🗂️ Quick Folder Ignore — Add a root-qualified folder rule directly from the sidebar • 📋 Copy & Export — Copy content or export supported files as HTML or PDF • 🌐 Multiple Languages — Use the interface in supported languages • 🔒 Local Privacy — Files are viewed locally and are not uploaded for rendering 🚀 How It Works: Open the extension workspace to browse folders, create Markdown files, edit with a live split preview, search filenames and file contents, manage ignored paths, and use export tools. You can also open a supported local file directly in Chrome to render it with available viewing tools. ⚙️ Customizable Settings: Adjust file type filters, folder scan depth, recent tabs, zoom, theme, language preference, and ignored file or folder rules. Ignore rules support gitignore-style globs such as *.log, build/, and **/*.tmp, plus regular expressions using regex:/pattern/flags. 📦 Local-First Workflow: Local viewing works offline after installation. No account is required for free viewing features. Network access is only used for optional Pro checkout, login, and license verification.
