Is the preview safe against malicious Markdown?

Yes. The preview renders inside a sandboxed iframe, and by default raw HTML tags are sanitised so pasted content cannot execute scripts.

Can I get a table of contents automatically?

Yes — enable table of contents generation and choose the heading depth, list style and where it is inserted in the output.

Does it support GitHub task lists and tables?

Yes, GitHub-flavoured Markdown extensions including tables, task list checkboxes and strikethrough are supported via the GFM toggle.

Can I convert HTML back into Markdown?

Yes, switch to the HTML → Markdown direction for a basic reverse conversion covering headings, links, lists, emphasis and code.

Can I export a complete standalone HTML page?

Yes — enable 'full document' mode to wrap the output with ` `, ` ` meta tags, a chosen title and a light or dark inline theme.

About markdown to html converter

Markdown to HTML converter renders GitHub-flavoured Markdown into HTML using the `marked` library, with a live sandboxed preview so you can see exactly how it will look before copying the output.

Control heading anchors and an auto-generated table of contents, code block formatting, smart typography, link and image handling (lazy-loading, figure wrapping, nofollow), and whether raw HTML is sanitised out of untrusted input.

Output can be a plain HTML fragment or a full standalone document with meta tags and a light/dark theme, pretty-printed or minified. A basic HTML → Markdown reverse conversion is included too.
