    Frequently Asked Questions

    What is GitHub Flavored Markdown (GFM)?

    GitHub Flavored Markdown (GFM) extends standard Markdown with extra features: tables (using | syntax), task lists with checkboxes (- [ ] and - [x]), strikethrough text (~~like this~~), fenced code blocks with syntax highlighting (```language), and autolinks. GFM is the format used on GitHub for README files, issues, and pull requests.

    How do I convert Markdown to HTML?

    Paste your Markdown text into the left editor pane. The HTML output and rendered preview update automatically in real time as you type. Use the tabs on the right to switch between the rendered Preview, raw HTML Source, and auto-generated Table of Contents. Click "Copy HTML" to copy the output to your clipboard, or "Download HTML" to save it as a file.

    Can I convert HTML back to Markdown?

    Yes. Click the "⇄ HTML → MD" button in the toolbar to switch to reverse conversion mode. Paste your HTML into the left pane and the Markdown equivalent will appear in real time on the right. The reverse conversion uses the open-source Turndown library for accurate HTML to Markdown translation, supporting tables, code blocks, lists, and all standard elements.

    How does the Table of Contents feature work?

    Switch to the "TOC" tab on the right pane to see an auto-generated table of contents based on all h1–h6 headings in your Markdown document. Each item is indented according to heading level and links directly to the corresponding section in the preview. All headings in the preview also get clickable anchor links (# symbol on hover) for easy sharing.

    What keyboard shortcuts are available?

    The editor supports: Ctrl+B (bold — wraps selection in **), Ctrl+I (italic — wraps in *), Ctrl+K (link — inserts [text](url) pattern), Ctrl+Shift+C (inline code — wraps in `backticks`), Ctrl+S (download the converted HTML file). On Mac, use Cmd instead of Ctrl. Tab inserts 2 spaces for consistent indentation.

    Is my content private? Is anything uploaded to a server?

    Your content is 100% private. All Markdown to HTML conversion runs entirely in your browser using the marked.js library — nothing is ever sent to any server. There is no account required, no tracking of what you write, and the tool works offline once the page is loaded. Your documents stay on your device.
