Markdown Viewer Premium

Markdown Viewer Premium turns Markdown files you open in Chrome into clean, readable documents — with diagrams, charts, math and highlighted code — instead of plain text. Everything is rendered in your browser and works offline. FORMATTED PREVIEW • GitHub Flavored Markdown: tables, task lists, footnotes, GitHub alerts and Obsidian callouts. • Code highlighting for over 100 programming languages, with a copy button on every block. • Math formulas written in LaTeX. • Five themes: light, dark, system, sepia and solarized. Interface in English, Japanese and Vietnamese. DIAGRAMS AND CHARTS Write them in code blocks inside your Markdown and they are drawn in place: • Mermaid — flowcharts, sequence, class, state and ER diagrams, Gantt charts, mind maps and more, with an interactive view you can zoom and pan. • PlantUML, Graphviz and Vega-Lite charts, rendered without any server. EXPORT • Save the document as PDF, Word or a standalone HTML file, with diagrams and formulas included. • Copy it as Jira or Backlog markup, ready to paste into a ticket. NAVIGATION • An outline of the headings beside the text, which you can resize or hide. • Search inside the document and keyboard shortcuts (press ? to see them). BACKLOG AND JIRA • Files written in Backlog or Jira wiki notation are shown formatted too. • On a Markdown file in Backlog Git, a Preview button appears next to Download and History and shows the file formatted, using your existing Backlog sign-in. HOW TO USE • Open a link to a raw Markdown file — for example a raw file on GitHub or GitLab — and it is shown formatted. Regular web pages are left as they are. • For files on your computer, open chrome://extensions, choose Details for Markdown Viewer Premium and turn on "Allow access to file URLs". Then drag a file into Chrome. PRIVACY The extension collects no data and has no analytics. Documents are rendered in your browser and are never sent anywhere.
