What is a Markdown to HTML converter?
Markdown is a lightweight plain-text syntax for formatting: # for headings, **bold**, - for lists and backticks for code. Browsers can't display it directly, so it has to be turned into HTML first. This converter does that in your browser using the marked parser and shows the result side by side, which makes it handy for README files, documentation, blog posts written in Markdown, and content you need to paste into a CMS that only accepts HTML.
Supported syntax
| Markdown | HTML output |
|---|---|
## Setup | <h2 id="setup">Setup</h2> |
**bold**, _italic_ | <strong>, <em> |
[link](/docs) | <a href="/docs">link</a> |
- [x] Done (GFM) | <li><input type="checkbox" checked disabled> Done</li> |
~~old~~ (GFM) | <del>old</del> |
| ```js fence | <pre><code class="language-js"> |
GitHub-flavored Markdown (GFM) adds pipe tables with column alignment (|:---|:---:|---:|), task lists, strikethrough and automatic linking of bare URLs. Fenced code blocks keep their language as a language-* class, which syntax highlighters such as Prism or highlight.js pick up.
Is the generated HTML safe?
Markdown allows raw HTML, so a document can contain <script> tags, onerror= handlers or javascript: links. The preview is always cleaned with DOMPurify before it is shown, and by default the HTML output is sanitized the same way. If you are converting user-submitted Markdown on your own site, sanitize on the server too — client-side cleaning only protects this page.
Options explained
- Line breaks become <br> — standard Markdown joins lines within a paragraph; GitHub comments instead treat every newline as a line break. Enable this to match comment-style behavior.
- Heading IDs — adds GitHub-style
idattributes (lowercase, hyphenated, de-duplicated with-1,-2) so you can link to#installationor build a table of contents. - Full HTML document — wraps the output in
<!doctype html>,<head>and<body>, using the first heading as the<title>.
Tips
Leave a blank line before lists, tables and fenced code — many “why isn't this rendering?” problems come from a missing blank line. Need to go the other way? Use the HTML to Markdown converter, and tidy the result with the HTML Formatter.

Outils complémentaires : Markdown to HTML
- Markdown to Webflow Rich Text — Paste Markdown, check the preview and copy it as formatted rich text — headings, lists, links and bold text land correctly in Webflow’s Rich Text element.
- HTML Entity Encoder — Escape < > & " so text is safe to show in HTML, convert accents and symbols to named or numeric entities, or decode entity-filled HTML back to plain text.
- Compteur de mots — Collez ou saisissez votre texte pour compter en temps réel le nombre de mots et de caractères, ainsi que la durée de lecture et de prononciation, la densité des mots-clés et la longueur des titres, méta-descriptions et publications sur les réseaux sociaux à des fins de référencement.
- Vérificateur de différences — Collez une version originale et une version modifiée pour comparer côte à côte les lignes ajoutées, supprimées et modifiées — les mots exacts qui ont été modifiés étant mis en évidence dans chaque ligne.
