Convert Markdown to HTML

What is Markdown to HTML Converter?

Render Markdown (GitHub-flavoured) as HTML in your browser, with optional HTML sanitisation via DOMPurify so pasted content is safe to drop into a live page. Toggle between rendered preview and raw HTML source. Great for turning a README into a web excerpt, previewing a blog post before publishing, or generating boilerplate HTML that you can further tweak.

How do I use Markdown to HTML Converter?

1. Paste Markdown into the input panel.
2. Switch between Preview and HTML views.
3. Toggle sanitise off (at your own risk) only if you trust the input to include raw HTML.
4. Copy or download the output.

Common use cases for Markdown to HTML Converter

• Pasting formatted content from Notion into a WordPress post.
• Converting a README into a blog draft.
• Generating email-safe HTML from a text-only brief.
• Previewing a PR description before sending.
• Building a static page from notes without a generator.

Common pitfalls and how to avoid them

• Images stripped after paste — Some CMSes block external images by default. Upload the image separately and re-link it with the CMS media picker.
• Task lists render as plain bullets — Not every HTML context supports GitHub task-list markup. Keep the markdown for GitHub, and strip checkboxes for WordPress/Ghost.
• Custom HTML in the source is gone — DOMPurify strips scripts and event handlers. Structural tags survive; scripts do not. This is intentional.

When should I use Markdown to HTML Converter?
