Processed locallyAbout Markdown to HTML
Renders Markdown to HTML and rejects dangerous link protocols such as javascript:.
- 1
Covers the subset documents actually use: h1–h6, bold/italic/strikethrough, inline code and fenced code blocks with a language, links (with `target="_blank"` added), images, unordered and ordered lists, blockquotes, horizontal rules and paragraphs.
- 2
Markdown from anywhere previews safely: raw `<script>` / `<style>` / `<iframe>` blocks are escaped into visible text, and `javascript:` or `data:text/html` link targets are replaced with `#`.
- 3
GFM tables, task lists, footnotes and indented nested lists are not parsed — they come out as plain paragraphs (nested lists even produce malformed list markup), so use a full renderer for rich documents.
- 1
Paste the Markdown
The sample covers headings, lists, inline code and a fenced block; compare the output against it.
- 2
Check the generated tags
Heading levels map to h1–h6, code blocks get class="language-xxx", and links pick up target.
- 3
Copy the HTML
Paste it into a page or an email template — script-like content has been escaped.
There is no GFM table parsing here: splitting cells needs column alignment, and regex-based cell matching goes wrong easily, so it is left out on purpose. Use a full Markdown renderer when you need tables.
No, deliberately: `<script>`, `<style>` and `<iframe>` blocks are escaped to text first, and `javascript:` or `data:text/html` link targets become `#`. That way Markdown pasted from elsewhere cannot execute anything while you preview it.
