Key concepts
Markdown HTML conversion turns headings (#), bold/italic, links, lists, and inline or block code into tags for blog drafts, email bodies, and CMS paste. Text is escaped first, then only allowed tags are combined, so it is not for script injection. It is a lightweight markdown converter that turns headings, bold, and lists into HTML tags for a blog draft or email and shows a preview as well. When you need HTML source to paste into a CMS, you check lightweight markdown conversion and preview on one screen.
There are no GFM tables, footnotes, or math. The markdown preview tool is for on-screen checking; this tool is for copying HTML source. Conversion runs only in the browser with no server rendering. GFM tables, task lists, and math are omitted, so complex documents need a dedicated renderer. It is not for script injection. Documents with many tables, footnotes, or formulas should use a dedicated renderer; this tool fits headings, emphasis, links, lists, and code.
Example
Enter # Heading, **bold**, *italic*, and [link](https://example.com) and convert: h1, strong, em, and a tags appear in the HTML field, and the preview below shows the same formatting. Two - item lines become ul/li. Table syntax can remain as plain text. Convert **important** and `code` and strong and code tags appear in both the HTML field and the preview. You can check in the preview right away whether quote syntax and inline code become tags.
