Markdown to HTML Preview
Pure client-side, live Markdown preview. Nothing leaves your browser.
This tool converts the Markdown you type into HTML and previews it live, supporting headings, bold/italic, lists, links, code blocks, tables, and other GitHub-flavored Markdown (GFM) syntax out of the box. For safety, the rendered HTML is always sanitized before it's displayed — <script> tags, inline event attributes (like onerror), and similar potentially malicious content are automatically stripped.

FAQ
What Markdown syntax is supported?
Standard Markdown, plus common GitHub-flavored extensions (GFM) like tables, strikethrough, fenced code blocks, and autolinks.
Is my input uploaded anywhere?
No. Parsing and rendering happen entirely in your browser. The page itself is a static export with no backend endpoint that could ever receive your data.
What happens if I type a <script> tag in my Markdown?
The rendered output is sanitized with DOMPurify — <script> tags, inline event attributes (onerror, onclick, etc.), and javascript: links are automatically stripped and never executed.
