MDTool is a free, browser-based Markdown converter. Conversion runs client-side: files aren’t uploaded to a server and no account is required.
MDTool converts Markdown to PDF (selectable vector text, four themes, A4 or Letter, rendered Mermaid diagrams), to Word .docx files that use Word’s built-in Heading 1–6 styles (so the Navigation pane and automatic table of contents work), and to HTML. It also converts Word documents and HTML back to Markdown, and includes a visual Markdown table generator.
MDTool uses marked with GitHub Flavored Markdown enabled, highlight.js for code, and Mermaid for diagrams.
