Markdown to HTML highlights

  • Side-by-side Markdown, HTML source, and rendered preview for quick QA.
  • GFM-flavored parsing with toolbar shortcuts for headings, lists, and code fences.
  • DOMPurify sanitization plus safe link targets on external anchors.
  • Copy HTML or download a minimal document shell for demos and CMS imports.

How to work faster

  1. Draft in the left editor — use toolbar inserts when you do not remember syntax.
  2. Scan the HTML pane for semantic tags before shipping to production templates.
  3. Review the preview as if you were a reader on mobile; fix heading depth early.
  4. Copy or download once satisfied; re-run after any major structural edits.

Where teams adopt it

README conversions, knowledge-base migrations, and email-to-web reuse all benefit from a fast Markdown loop. After HTML exists, tune discoverability with the meta tag generator so titles and snippets match the new content.

Validate length before publishing

Drop plain-text excerpts into the word counter to double-check editorial limits after Markdown removes formatting noise.
