Fast, Semantic Markdown Publishing for Web Developers & Content Writers

Frequently asked questions
What flavor of Markdown does this converter support?
Toolhast uses marked, a high-speed compliant parser supporting GitHub Flavored Markdown (GFM), including tables, task lists, code blocks, autolinks, and strikethroughs.
Is the generated HTML sanitized against malicious XSS?
Yes. The HTML output is thoroughly cleaned and sanitized, stripping unsafe JavaScript script tags and insecure attributes so you can safely use the output in CMS platforms like WordPress, Ghost, or Webflow.
Does my text leave my browser during conversion?
No. All parsing and HTML compilation occur 100% inside your browser's JavaScript engine. Your private documentation, blog drafts, and proprietary code never reach external servers.
Can I use this converter offline?
Yes. Once loaded, the page functions completely without an active internet connection.
How do I embed images and hyperlinks in Markdown?
Use standard Markdown syntax: [Link text](https://example.com) for hyperlinks and  for images.
Is there any character or document size limitation?
No. You can convert short snippets or complete multi-chapter technical whitepapers without size throttling or premium paywalls.
