Frequently Asked Questions

Is my Markdown sent to a server?

No. All Markdown parsing, HTML rendering, syntax highlighting, and export operations happen entirely in your browser. Your source content is never transmitted to any server.

What flavor of Markdown is supported?

Basic mode supports CommonMark. Advanced mode adds GFM extras: task lists, strikethrough, autolinks, footnotes, YAML front-matter, KaTeX math, Mermaid diagrams, and emoji.

Can I export to PDF or HTML?

Yes — in Advanced Mode. Download standalone HTML, raw Markdown, or use PDF / Print for a print-optimized layout.

Is raw HTML in Markdown safe?

All HTML output is sanitized before DOM injection — script tags, inline event handlers, and javascript: URIs are stripped. The sanitizer always runs last.

What are the keyboard shortcuts?

Cmd / Ctrl + Enter forces a manual re-render. Escape exits reading mode or closes the help drawer.
