About this tool
What does it do?
It renders GitHub-Flavored Markdown — headings, lists, tables, task lists, code blocks — into sanitized HTML you can paste into blogs, docs and CMS editors, without hand-writing tags.
How to use it
- Write or paste Markdown on the left, preview HTML on the right.
- Copy the sanitized HTML for your target platform.
- Use the HTML editor tool for fine-tuning the result.
Examples
- Drafting a README with tables and code samples.
- Converting meeting notes into a formatted email.
- Preparing CMS content without touching the WYSIWYG.
Important limitations
- Output is sanitized: raw HTML/JS in your Markdown is stripped for safety.
- Flavor differences exist (GFM vs CommonMark vs platform quirks) — verify tables and footnotes.
- Styling comes from your site’s CSS, not the converter.
Privacy
Rendering is local. Drafts — often confidential — never leave your browser.
Frequently asked questions
Why did my HTML disappear?
Sanitization removed it. Markdown is for content; use the HTML editor for markup.
Tables look broken — why?
GFM tables need the header separator row (| --- |). One missing pipe breaks the table.
Can I go back from HTML to Markdown?
Approximately, with dedicated converters — formatting fidelity varies.
