About Markdown Preview

A Markdown Preview editor compiles simple markdown tags into fully formatted HTML layouts matching Github Flavored Markdown rules.

How It Works

The tool runs a fast client-side markdown compiler that escapes unsafe tags and renders tables, code spans, lists, and checklists locally.

How to Use Markdown Preview

  1. Type or paste Markdown syntax into the left text editor area.
  2. Observe the live formatted preview render automatically in the right pane.
  3. Click the Copy HTML button to fetch the compiled HTML code.

FAQ

Is HTML inside the Markdown sanitised?

Yes. Raw HTML is parsed, attributes are filtered against an allow-list, and dangerous protocols like `javascript:` are stripped before the preview is rendered.

Under the hood

A tiny incremental Markdown parser based on commonmark-style block + inline passes, with GFM additions (tables, task lists, autolinks, strikethrough). The renderer escapes by default and only un-escapes for the explicit HTML pass-through path.
