Does it support GitHub-flavored Markdown (tables, task lists)?

Yes, tables, task lists, strikethrough, and the other GFM extensions render correctly in the live preview, not just base Markdown.

Is the rendered output safe if I paste Markdown with embedded HTML?

Yes, the rendered HTML is sanitized before display, so embedded scripts or unsafe markup can't execute.

About

Markdown Editor is a split-pane editor with a live preview that updates as you type, supporting GitHub-flavored Markdown — tables, task lists, strikethrough — plus syntax-highlighted code blocks. It's useful for drafting a README or release notes and seeing exactly how they'll render before you commit them. Rendered HTML is sanitized before display. Everything runs locally; your Markdown source is never uploaded.
