About online Markdown to HTML
Turn Markdown notes, README snippets, or chat formatting into HTML for previews, emails, or CMS paste-in.
Online Markdown to HTML capabilities
Common syntax
Headings, lists, links, emphasis, blockquotes, and fenced code blocks map to semantic HTML elements.
Not a full spec
- Tables, footnotes, and some extensions may differ from GitHub-flavored Markdown.
- Output is not sanitized—do not paste untrusted Markdown into production pages without a sanitizer.
Common use cases
README preview
Check how docs render before pushing to GitHub or an internal wiki.
Email & CMS
Convert a draft to HTML for rich-text editors that accept HTML paste.
Chat export
Turn formatted chat logs with Markdown into static HTML snippets.
Frequently asked questions
- Is Markdown the same as HTML?
- Markdown is a lightweight authoring format; HTML is the browser markup. One Markdown document can map to many HTML structures depending on parser rules.
- Why do tables look different from GitHub?
- GitHub uses GitHub-Flavored Markdown extensions. This tool targets common core syntax—complex tables may need a GFM-specific preview.
- Is the HTML safe to embed?
- Only if you trust the source. Malicious Markdown can include raw HTML or javascript: links—sanitize before publishing.
