Convert standard markdown to HTML: headings, bold/italic/strikethrough, lists, links, images, code blocks, blockquotes, horizontal rules
Raw HTML in the source is escaped (script tags / event handlers become visible text, not active markup) — preview is safe
Side-by-side editor and preview, or HTML-source view
Regex-based converter — handles common markdown but not nested lists or advanced GFM features (tables, footnotes, task lists)
For full CommonMark / GFM compliance, use markdown-it or marked in your code

Pasted HTML is escaped — `<script>alert(1)</script>` shows as visible text, not executable code. This keeps the preview safe from XSS.
For tables, footnotes, definition lists, and other GitHub-Flavored Markdown features, this tool falls short. Use markdown-it for those.
Code blocks add a `language-XXX` class on `<code>`; pair with a highlighting library (Prism / highlight.js) when you render the output.
Bold + italic combined (`***text***`) maps to `<strong><em>text</em></strong>`.
Headings use ATX style (`#` to `######`); setext (underline `=====` / `-----`) is not supported.
